Description

Shoe sole and shoe insole for measuring body weight

The present invention relates to a shoe sole for measuring a mass or a weight, in particular a body weight, which can also be configured as a shoe insole and thus to insert into a shoe for measuring body weight. The invention further relates to a corresponding method for producing a shoe sole or a shoe insole. Furthermore, the invention relates to a shoe sole for measuring a mass or a weight, in particular a body weight, as well as a corresponding shoe insole with at least one arranged relative to a horizontal part of the shoe sole at an angle pressure-sensitive sensor. The invention also relates to a shoe sole for measuring a mass or a weight, in particular a body weight, as well as a corresponding shoe insole having at least one pressure sensor attached to an outer surface of the sole. The invention also relates to at least one method for controlling a plurality of interconnected pressure-sensitive sensors.

An area of application of the fitness industry are electronic expansions of existing sports equipment with additional sensor technology, which picks up data of the exercising person during his training session and makes it accessible to an electronic evaluation. So fitness bands are already known, which measure by means of a GPS sensor, how far a jogger runs during a training session. After training, he can read this training data from his cell phone. Also known are pressure sensors in shoes, z. B. sports shoes to perform a gait analysis. Other application scenarios such electronic add-on modules are z. B. the therapeutic training, which gives the trainee a feedback, whether he exceeds a certain load or just whether he needs to spend more force. It is also possible, by means of a pressure sensor within a shoe, a technical device, eg. B. to control an electronic, virtual gas pedal. DE 42 37 072 C1 shows a flat designed film pressure sensor, in particular for seat occupancy detection in a vehicle seat, the electrical resistance decreases with increasing normal force on the film surface.

WO 2012/152420 A1 shows an application scenario of a sensor which transmits data of a jogger, which is monitored by means of a motion sensor and a pressure sensor, to a mobile phone. Thus, a motion picture analysis or a gait image analysis can be performed.

DE 295 12 711 U1 shows a measuring system for the static and dynamic pressure distribution measurement on the sole of a human foot with the aid of force measuring soles. Furthermore, a telemetry unit is provided, which forwards measured data to a processing unit. Furthermore, a resistive pressure sensor is shown in a force measuring sole.

However, the prior art has several disadvantages. The determination of data is often limited by a limited power supply, or by the size of the computing and storage unit. Another reason for limiting daily measurements is the cost or technical effort for the intended identification of data.

Since the invention of the shoe, it serves the user to protect against excessive stress and strain on the feet, extremities and the body. For example, forces picked up, held or carried by the head, hands, trunk or legs must be dissipated to the floor via the feet. The feet balance the forces acting from top to bottom with their musculature, with the aid of the organs of balance and the available coordinative and motor possibilities and the available power, from bottom to top. The feet transmit the load of the body, plus any weights, from e.g. B. entrained objects on the ground. With the development of the shoes longer and at the same time gentler movements could be carried out. Shoes thus have a variety of tasks and are today, for example, selected by application, price, comfort, personal taste and aesthetics. For example. A sports shoe is subject to special criteria. It differs depending on sports and disciplines. Within a sport, such as athletics or football, the sports shoe has different characteristics. The tuning of the damping is a possible feature. People who carry a higher body weight, need a higher cushioning in the shoe to achieve added value in comfort. A new discipline in science and medicine was discovered with the further development and adaptation of the shoe to different circumstances, handicaps and illnesses. Investigations with the aid of the standing and step analysis on the countersink, spread or flat foot are a standardized means of examination.

Gait analysis / pressure point measurement was added with the development of sensor technology and computing power on special surfaces. Gait images are used to create special shoes in orthopedics. Extremities are adjusted with shoes to compensate for differences in length in time in childhood. With the orthopedic services, for example, faster and one-sided wear of the hips are limited and thus spared. Missing toes are compensated in the shoe, as footprint differences in the foot led to more extensive illnesses. In recent years, the sports shoe has also been given attention in these areas. A gait analysis before buying a sports shoe is usually carried out in larger sports shops. Here the advantages and disadvantages of special shoes can be made visible to the user. Since the buyer of the shoes often knows nothing of his deviating gait to the ideal line, this type of measurement is often used for the first indication of wear of the joints by, for example, length differences of the extremities, postural errors, accidents or excessive ambition in sports.

A distinction as to whether the pain derives from the stress of a healthy workout or a static overload is often irrelevant. The load of the body, for example, the muscles and joints, is dosed to match the performance of the athlete. Pain in the muscles and joints are a sign of overwork. In the case of the reduction of signs of overload, initially only sufficient rest helps. In order to recognize this overload, tools are nowadays used that electronically monitor the movement and movement performance. The applied technology in the shoe, equipped with GPS and motion sensors, saves z. For example, the distance traveled and the time. A control of the user and at the same time an indication of an overload are, however, not derived from this. What is missing is a value that shows the characteristics of a substantial deficiency requirement, such as states of exhaustion, illness or handicap. Substantial, for example, the measurable changes of standing or running patterns that occur due to the effects of mass and / or force distribution, eg. In a stressed, diseased or handicapped person.

The determination of data in everyday life thus becomes advantageous only if the ease of handling and a reasonable technical effort add value, i. if the expected performance exceeds the effort for the respective relative use case.

Although current systems offered on the market, such as microcomputers, have high functionality in terms of computing power and have simple and common interfaces. The size of a microcontroller depends on the power and the connections and is not comparable to the invention described here.

A continuous measurement of mass and mass distribution in the shoe is not known. The existing technology is currently too large for such an application and is not portable in everyday life in a shoe, as a shoe insert, or attached as a clip system outside of the shoe and on the sole of the foot. The solution to this problem is, inter alia, the subject of the present invention.

The analysis of the stance or gait line is shown with special measurements of the pressure distribution, which arises during the rolling process of the foot on a foil-like and equipped with various sensor surface and is, inter alia, the subject of the present invention.

For measurement and evaluation conventionally complex equipment is required, which are very special to use and extremely expensive. An especially continuous assessment of the mass or weight of humans is not possible with today's technology. The existing technology is primarily used for medical applications in the clinical or scientific field, such as diagnostics, in sports therapy, for example, for the analysis of errors in high-performance sports, as well as in rehabilitation. The gait and running analysis is also used, for example, in pain therapy as a diagnostic agent.

The measurements are conventionally performed by specially trained scientists in sports medicine facilities, specialist medical facilities such as orthopedics and sports medicine, podiatrists and manually-operated facilities. Current measurements of mass and mass distribution, or force and force distribution are offered outside of the shoe on treadmills or measuring films.

For capacitive measurements, it must be taken into account that each person or the measured surface has a resistance that is also variable in size, density, humidity. A change happens by touching a third person. Moisture such as body sweat, drinking, rain change the reading. So a calibration for a weight measurement is practically impossible. Piezoelectric measurements can not determine static values. A footfall creates a change in capacitance on the electrically conductive surface. Then the power supply is switched off and the time is measured how long the current flows from the sensor.

Conventional capacitive sensors work like capacitors. The larger and denser the receptive body that is to be measured, the longer it delivers the stored energy. Therefore, a large and dense body takes longer to measure than a small body. A body weighing only a few grams will usually be measured in just a few milliseconds. A human body that weighs, for example, 80 kilograms, releases about 1 second after the power is turned off. Thus, the number of measurements per second is limited.

If you use several capacitive sensors, the problem can be shared. However, the division is only very limited possible for a variety of reasons, such as the limited number of connections to the microcontroller. To measure 100 kilograms with capacitive sensors one hundred times a second, would be a very large without additional layers of sensors Number of sensors necessary. However, the required number is out of all proportion to the possibilities of even the most powerful AD converters and microcontrollers.

Even future, powerful microcontrollers with far more connections will always need a space and resource-saving solution on carriers and semiconductors.

It is thus, inter alia, an object of the present invention to provide a shoe sole or a shoe insole, which can be produced with little technical effort and yet a weight, especially a body weight or a weight distribution measures very accurately, advantageously, the measurement should be continuous , It is a further object of the present invention to provide a corresponding shoe, which is equipped with an advantageously designed sensors. Another object is to provide the simplest possible manufacturing method of such a shoe sole.

It is a further object of the present invention to provide a shoe sole for measuring a mass or a weight, in particular a body weight, as well as a corresponding shoe insole, the shoe sole having at least one pressure-sensitive sensor arranged at an angle relative to a horizontal part of the shoe sole , Another object of the invention is to provide a shoe sole for measuring a mass or a weight, in particular a body weight, as well as a corresponding shoe insole with at least one pressure sensor attached to an outer surface of the sole. Furthermore, it is an object of the invention to provide a method for controlling a plurality of interconnected pressure-sensitive sensors.

These and other objects are achieved by the independent claims. Dependent claims relate to preferred embodiments.

Accordingly, a shoe sole is provided for measuring body weight, having a first layer comprising a first set of cross-connected pressure sensors arranged for measuring weight in a first measuring range. According to a further aspect of the present invention, the shoe sole comprises at least one second layer with a second set of cross-connected pressure sensors arranged for weight measurement in a second measuring range. Thus, the proposed shoe sole can have a plurality of layers, each of which has its own measuring sensor system, ie, in particular a first or a second set of cross-connected pressure sensors. In this case, it is possible to provide such a layer by means of a special printing process, wherein a further layer is printed onto a specific layer and thus a shoe sole is produced in layers. Thus, the shoe sole according to the invention can be provided in a simple manufacturing process, in which z. B. a conventional substrate is printed with the individual layers. The person skilled in the art will be aware of further manufacturing possibilities, such as the provision of such an arrangement of layers.

A problem of Force Sensing Resistor, FSR, sensors and other resistive and also piezoelectric and capacitive sensors is the limited measuring range. For example, FSR sensors measure well only in the range of 1 to 4 kilograms and become inaccurate with every kilogram. At 10 kilograms, a maximum has been reached. In the following, pressures are also indicated by the unit "kg." A person skilled in the art is familiar with a conversion to the corresponding units of the pressure, for example, through the use of the gravitational constant.

In order to calculate the inaccuracies, pressure distribution curves are used. An advantageous solution consists in the superposition of other sensors on the board in several layers. The layers of the invention cost only a fraction of a single FSR sensor. However, a layer on the board can have hundreds of mass-measuring sensors. The layer structure according to the invention can thus measure mass in the milligram range and also tons of masses with a three-dimensional matrix. The inaccuracy ranges caused by the maximum utilization of the resistors from 0 to 1023 in the exemplary use of a 10-bit AD converter can be omitted by further layers according to the invention. Another exemplary use relates to a 12-bit AD converter with a measurement range from 0 to 4095, for example from Nordic Semiconductors.

In an application according to the invention, a simple but functional arithmetic unit is provided, which is specifically aimed at the goal of a low-cost solution. The arithmetic unit will continue to be designed specifically with simple sensors, targeted and low-energy to be able to communicate. A low-energy radio solution can finally send the data to the image output, preferably a mobile terminal, such as a smartphone, with a high transmission rate.

The arithmetic unit can send the measurement results to the evaluation unit individually as well as synchronized, so that thus several measurement results from several measurement locations can be calculated and evaluated. The inventive technology or technology, has sensors, processing unit, memory unit, converter, radio unit, power supply and better handling, preferably also via an induction charge or solar charge. In particular, induction charge and / or solar charge of an optionally provided in the shoe sole energy source of the present invention.

The first layer has a first quantity of pressure sensors, which preferably may coincide in number with the second quantity of pressure sensors of the second layer. This is not essential. Rather, it is possible in one embodiment that both layers are not formed equally large, so that only at certain load areas within a shoe several layers of pressure sensors superimposed and present at other stress zones only one layer. So it may be advantageous that, for example, on a heel area and a ball area several layers of pressure sensors are installed, while under the toes typically low loads occur and therefore z. B. only one layer is present.

The individual layers can be designed such that they measure different weight ranges. Thus, for example, a first layer may be designed to provide only pressure sensors which can measure in a measuring range of 1 to 10 kg. For example, a second set of pressure sensors provided in a second layer may be configured to measure only a pressure of 0 to 5 Kg. Through these different measuring ranges, the weight loads, which hit a certain point within the shoe, add up and thus can calculate a total weight. Thus, it is particularly advantageous according to the invention that the measurement accuracy can also be calibrated by means of multiple layers of pressure sensors such that different sensor layers, each with different pressure sensitivity, can be advantageously selected and stored one above the other such that they are practical Any measurement accuracy can be achieved. Thus, it is possible according to the invention that for certain heavy load sensors and individual, particularly sensitive pressure sensors can be installed so that virtually any measuring ranges can be detected in very high accuracy by adding the individual measured force effects.

Thus, it is avoided according to the invention that a measurement inaccuracy of only one sensor layer leads to a falsification of the measurement result. According to the invention, the expected forces acting can thereby be measured very accurately, so that measures depending on the expected pressure per point a suitable choice or number of load sensors at this point.

According to the invention, the pressure sensors are switched in such a way that a smaller area results, for example compared with a parallel connection. Typically, pressure sensors to be used are designed to be elongated, which, if they are arranged in a surface along side by side, occupy more space than the cross-connected pressure sensors according to the invention. With the special cross-over circuit, it is thus also possible to provide fewer tracks for their control, since in a Ν ^χ Μ matrix arrangement of pressure sensors only N + M outputs must be tapped in order to control each individual pressure point can. An example of this is shown in FIG.

According to another aspect of the present invention, the first and second measurement ranges are at least partially different. This has the advantage that different measuring ranges per pressure point can be set up to also be able to scale the accuracy of the pressure measurement.

According to another aspect of the present invention, the first and second measurement ranges are continuous. The continuous measurement has the advantage that no discrete measurements in the sense of a time-discrete measurement or in the sense of a discrete measurement range falsify the measurement result. Thus, for example, over a certain period of time, the course of a pressure curve, ie an application of weight at a certain measuring point, can be measured continuously. In addition, a decimal number can be continuously measured, which has the particular advantage that no binary measurement is made. Conventional sensors are partial set up only to detect whether there is a pressurization or not. According to the invention, however, a continuous measured value can be determined here.

According to another aspect of the present invention, the pressure sensors of the first layer are disposed substantially over the pressure sensors of the second layer. This has the advantage that merely adding up the individual measured pressure sensor values is sufficient to determine the weight at a certain pressure point. The pressure sensors are only arranged substantially one above the other, as due to the production or according to the force applied to a pressurization, a slight deflection of the individual sensors can take place against each other.

According to a further aspect of the present invention, the electrical resistance per pressure sensor changes after it has been loaded with a weight. This has the advantage that conventional pressure sensors can be used, which are designed to be particularly thin and also can be produced without great technical effort.

According to another aspect of the present invention, the resistance change allows a conclusion about the size of the applied weight. This has the advantage that only by means of these sensors, or by means of the measured change in resistance, can a weight, which presses on a specific measuring point within the shoe, already be measured by a computing unit provided.

According to a further aspect of the present invention, the pressure sensors can each be read out independently of each other. This has the advantage that all pressure sensors can be addressed separately within the shoe sole, and that, for example, only a certain area can be read. Thus, it may be advantageous that only one ball area and / or one heel area is relevant for a measurement and thus further sensors can be switched off at another position.

According to a further aspect of the present invention, the first and the second layer each have a carrier layer with applied pressure sensors. However, it can also be provided in total only one carrier layer. This has the advantage that the individual layers need not be provided before a manufacturing process, but that only a carrier material is provided, to which the individual layers can be applied afterwards. This has the particular advantage that conventional soles can be retrofitted in such a way that they have the layer arrangement according to the invention.

According to another aspect of the present invention, the carrier layer is divided into non-conductive strips in tiles. This has the advantage that by means of the tiles a flow of current is prevented so that the measurement result is not distorted.

According to a further aspect of the present invention, the pressure sensors for reading by means of electrical conductors are coupled to a computing unit. This has the advantage that an arithmetic unit can already be provided with the sole of the shoe, which can either itself evaluate measurements, or merely switches on the measurement data to an external arithmetic unit.

According to another aspect of the present invention, the layers have breathing bridges. This has the advantage that a vapor barrier can be interrupted within the layer model. In this case, it may be particularly advantageous to arrange the breathing bridges over one another in such a way that the sole provides a respiratory bridge as a whole.

According to another aspect of the present invention, the shoe sole is formed as a shoe insole. This has the advantage that the shoe insole alone, i. can be provided without a surrounding shoe and thus conventional shoes can be retrofitted according to the invention.

According to a further aspect of the present invention, the shoe sole has at least one further sensor unit. Such a sensor unit may be a heart rate monitor, an electrocardiogram device, a temperature sensor, an acceleration sensor and / or a position sensor. This has the advantage that a large number of further sensors can be provided within the shoe sole which can cooperate synergistically with the pressure sensors in such a way that a large number of measurement results can provide a comprehensive picture of not only a weighting but also of a training behavior. According to another aspect of the present invention, the pressure sensors of different layers measure different measurement ranges. This has the advantage that a layer-by-layer measurement of individual measuring ranges is possible. The individual layers can be provided with little technical effort, since the same sensors can always be used per layer.

The object is also achieved by a shoe which has a shoe sole as described. In addition, the object is achieved by a method for producing a shoe sole with the steps of providing a first carrier layer and crosswise application of pressure sensors, which are designed for weight measurement in a first measuring range, for producing a first layer. The method may further comprise a step of providing a second carrier layer and applying pressure sensors over it, which are arranged to measure weight in a second measuring range, to produce a second layer, and to assemble the first and the second layer.

According to one exemplary embodiment, the shoe sole according to the present invention has at least one computing and storage unit, at least one transducer, at least one energy unit, at least one evaluation logic, at least one sensor system, at least one radio solution, carrier material for the electronic components, at least one mobile and / or stationary one Image unit and / or at least one device for receiving the components in or on a shoe. The shoe sole according to the present invention is generally less expensive, more flexible and combinable than conventional products.

It is another aspect of the present invention that different sensors can perform and compare similar measurements, add supplements, and combine with other applications. The shoe sole according to the present invention can measure at least one record in real time, store independently communicate with each other and independently evaluate results and trigger actions. The shoe sole according to the present invention operates autonomously and can independently communicate with other sensors. The shoe sole according to the present invention measures the continuous states and state changes of at least a participating sensor, such as preferably mass or force that act from the feet to the ground.

It is another aspect of the present invention that the continuous states and state changes that emanate from the feet, as well as from the outside act on the feet of at least one sensor, such as a temperature sensor, pressure, sound, moisture and / or Light sensor to be measured. It is a further aspect of the present invention that at least one camera and / or a photodiode can be controlled. The sensors fixed and / or mobile, in and / or outside in the shoe, z. B. in a sock, be installed.

The shoe sole according to the present invention may connect on a carrier material the components of computing and storage unit, sensors, transducers, amplifiers and / or radio unit. The size of the shoe sole according to the present invention may be at least the size of the footprint to be measured.

For example, for the shoe sole according to the present invention, a microcontroller or semiconductor is used, to which a special firmware directly allows the communication with the sensor system. The microcontroller can be installed on a transparent carrier unit, also as a chip on board. With individual sensors and / or combinations of different sensors, more complex data measurements can be carried out for complex applications.

It is another aspect of the present invention that two different sensors are used for different applications in the shoe for measurement.

A special app can create statistics from a further measured value in the shoe, for example from the stored temperature data inside and outside the shoe, and also suggest instructions for action for third parties.

The weight measured on the feet changes constantly in everyday life. Factors that contribute to the measured weight are, for example, clothing, whether the person is carrying one or more objects, whether the person is sitting or standing, etc. In other words: what am I wearing, am I sitting, standing on one leg, and much more. In everyday life, this information interesting for private as well as for business and / or commercial applications. The applications of the invention in everyday life are thus diverse.

With the device according to the invention can, for. B. an athlete / can measure his imprinting energy when sprinting or jumping disciplines. A weightlifter no longer needs a journal of his training and competition achievements. The fitness athlete can work out with short and long dumbbells, and his performances, repetition and sentence numbers and the execution of the movement are stored electronically. Also, fatigue states can be detected and recorded with the present invention. Thus, the degree of exhaustion can be determined by a time-dependent and / or dynamic measurement of the detected pressure change of the sensors.

In endurance sports, weight loss due to weight loss due to dehydration can be recognized. In school sports, movement deficits, for example, in the coordinated mobility can be seen. Procedures and hidden sources of error can be visually shown not only to the physical education teacher. Therapy approaches are shown faster with the invention. In the rehabilitation sport, performance enhancements are visible and therefore helpful even in the smallest change for trainer, therapist and for the patient, also as motivational aid. In prevention, set markers in the invention may, for example, also indicate deficiencies of the user. Sports shoes with weight sensors represent a gain for almost all sports and applications.

The shoe sole according to the present invention also determines data from postural defects or poorly fitting prostheses, which, for example, produce protective postures and lead to disharmonious weight shifts.

It is another aspect of the present invention that, for example, when fishing independently by app tasks are met. For example. the catch is weighed using the sensors in the shoe, with the angler holding the catch in his hands and the shoe measuring the extra weight.

With the present invention mass changes of the body during running, as well as weight loss can be measured. Also, the mass changes from the left to the right foot, or vice versa, to be measured. The invention further enables the following measurements or evaluations: the step length change in length and time, a one-sided load during the movement, disharmonies during the movement. The invention enables independent or autonomous reaction as soon as the trend within an application and the defined time changes. The invention can serve as a hinting system for the user and / or issue warning tones when overloaded. Conditions can be determined from the sensors in the shoe as well as the stored data in order to notify third persons about assistance by radio, or real-time data can be sent to third parties and / or information to social networks.

Furthermore, in fitness sports, the training weights can be measured, repetition numbers are determined, set rates are determined, the concentric course of motion is measured in time, the eccentric course of motion is measured in time, the movement speed and the drop during exercise are measured, the degree of exertion (eg light, medium , hard), the mass of total weight measured during a workout, for example on a specific device or as a daily performance on all fitness machines, the duration of a workout with and without pauses are determined, exercise or daily charts / plans and statistics automatically can be created and provided automatically for third parties in social networks as a product and / or as a marketing product, training data in closed and / or open (social networks) information spaces / circle e, the scaling to a single training repetition, even during the training break currently in real time as a view (eg. Maximum performance), are made available to the user and also to third parties, break times are determined and output to the user via sound, faulty or modified training principles are determined, situational visual and audio training notes are output, data is stored for short-term and long-term training, Coordinative and motor information on specific movement sequences are determined and stored, feedback on movement sequences and reaction times are measured and / or the sensitive behavior is determined with a defined motion request.

Furthermore, overloading, for example by shortened hip and thigh flexors and illnesses by evaluation of the past and / or in the comparison of data Determining load levels by a constant or changed concentric and eccentric motion (waveform in time and lift height) in the execution time and lift height, physical daily loads of a person, such. Officials, assembly line workers or masons are measured. Automated solutions with the shoe can control smart electrical systems in everyday life; for example, the shoe can switch the lighting on and off in rooms.

The invention also relates to a shoe sole for measuring a mass or a weight, in particular a body weight, as well as a corresponding shoe insole having at least one pressure-sensitive sensor arranged at an angle relative to a horizontal part of the shoe sole. The horizontal part of the shoe sole is the area of the shoe sole on which the sole of the foot, i. the Planta pedis, mostly rests. For the most part, in this context, the entire part of a normally formed foot sole preferably means without the transverse and longitudinal arch. According to the invention, the angle between the horizontal part of the sole and the at least one pressure sensor is defined by the angle between the horizontal part and the pressure-sensitive surface of the pressure sensor. Thus, according to the invention, the angle between the horizontal part of the shoe sole and the at least one pressure sensor may be 75 to 105 degrees or 1 to 45 degrees, preferably 85 degrees or 10 to 35 degrees. For example, the at least one pressure sensor may be attached to a pad, the pad being located on the horizontal part of the sole. Also, the at least one pressure sensor may be located on a support member to support the transverse or longitudinal arch of the foot. Also, according to the invention one or more layers arranged cross-connected sensors can be arranged at an angle relative to the horizontal part of the sole.

The invention also relates to a shoe sole for measuring a mass or a weight, in particular a body weight, as well as a corresponding shoe insole having at least one pressure sensor attached to an outer surface of the sole. Preferably, this outer surface of the sole of the Fußauflagefläche the sole upward, ie in the direction of body center of the person extends. As with the above-described shoe sole with at least one further arranged at an angle to the horizontal part of the sole pressure sensor, such a shoe sole according to the invention in addition to the vertical forces, ie the forces acting on the horizontal part of the sole, also horizontal forces be measured. This is, among other things, possible in the Dynamic movement also record shear forces that occur, for example, when braking, or even the forces that occur when the hoe is first placed on the run. An example according to the invention of a shoe sole with a plurality of pressure sensors attached to the outer surface of the sole is shown in FIG. Also, according to the invention one or more layers arranged cross-connected sensors can be mounted on the outer surface of the sole.

The measurement of these forces makes it possible to make statements about how e.g. strong deceleration from the high acceleration, for example in tennis, especially on non-yielding ground, e.g. Lawn, sports hall that affects the musculoskeletal system. In addition, foot deformities are detected not only in their vertical but also in their horizontal impact.

According to the present invention, the shoe sole which has one or more pressure sensors on the outer surface, and / or the shoe sole, which has at least one pressure-sensitive sensor arranged at an angle relative to a horizontal part of the shoe sole, can otherwise according to one of the aforementioned embodiments be configured of the present invention.

Thus, according to the present invention, the shoe sole, which has one or more pressure sensors on the outer surface, and / or the shoe sole with at least one pressure-sensitive sensor arranged at an angle relative to a horizontal part of the shoe sole, can comprise further pressure sensors, preferably on the horizontal part the sole, and more preferably according to one of the aforementioned aspects of the present invention. Thus, for example, the sole according to the invention, preferably on the horizontal part, a first layer having a first set of cross-connected pressure sensors, wherein the first set of cross-connected pressure sensors are arranged for weight measurement in a first measuring range. Also, the sole according to the invention, preferably on the horizontal part, at least a second layer having a second set of cross-connected pressure sensors, wherein the second set of cross-connected pressure sensors are arranged for weight measurement in a second measuring range. Preferably, even with such a sole, the first and second measuring ranges may be at least partially different and / or the first and second measuring ranges may be continuous.

Preferably, even with such a sole, the pressure sensors of the first layer can be arranged essentially above the pressure sensors of the second layer.

Preferably, even with such a sole, the pressure sensors can each be read independently of each other.

Preferably, also in the case of such a sole, the first and the second layer can each have a carrier layer with applied pressure sensors. Preferably, the carrier layer is divided by non-conductive strips in tiles.

Preferably, in such a sole, the pressure sensors for reading by means of electrical conductors are coupled to a computing unit.

Preferably, even with such a sole, the layers may have breathing bridges.

Preferably, such a sole may also comprise at least one further sensor unit from a group, the group comprising: an air pressure sensor, a pressure sensor, a heart rate monitor, an electrocardiogram device, a temperature sensor, an acceleration sensor and a position sensor.

The invention also relates to a method for controlling an amount of pressure sensors arranged in one or more layers, the quantity of pressure sensors being divided into several groups, comprising the following steps:

Determining whether a first pressure sensor associated with a group of pressure sensors detects a change in pressure; and

Activating at least a portion of the pressure sensors of the corresponding group if the associated first pressure sensor detects a change in pressure. The first pressure sensor thus assumes the task of a "guard", which determines whether a corresponding group of pressure sensors should / must be activated, for example, if a shoe sole is used, it can be determined whether the electrical resistance measured by a first pressure sensor changes If this is the case, the pressure sensors of a group assigned to the monitor pressure sensor are correspondingly activated / armed, so that movements, for example rolling movements over the sole, can advantageously be detected with a reduced data volume ,

Preferably, the activated pressure sensors are deactivated again after a predefined time T1. Preferably, the time T1 is in a range of 0.1 ms to 100 ms, more preferably in a range of 0.1 ms to 10 ms, and even more preferably in a range of 1 ms to 10 ms.

Preferably, the activated pressure sensors of a group are deactivated again if the first pressure sensor assigned to the group detects a renewed change in the pressure, preferably a change of the pressure below a predetermined limit.

Preferably, all pressure sensors of the corresponding group are activated if the associated first pressure sensor detects a change in the pressure.

Preferably, it is detected for each group of pressure sensors whether one of the respective group of pressure sensors associated first pressure sensor detects a change in pressure and at least a part of the pressure sensors of the respective group activated if the associated first pressure sensor of the respective group detects a change in pressure.

Preferably, the first pressure sensors are arranged in a strip. Preferably, this strip is disposed in close proximity to the set of pressure sensors.

Preferably, the first pressure sensor or the first pressure sensors are arranged separately from the associated group of pressure sensors and / or the quantity of pressure sensors. Preferably, the first pressure sensor or the first pressure sensors are part of the respective associated group of pressure sensors.

Preferably, in the case where the amount of pressure sensors is arranged in multiple layers, the respective groups of pressure sensors comprise a plurality of layers.

Preferably, the pressure sensors of the layers are arranged substantially one above the other.

Hereinafter, preferred aspects of the present invention will be described with reference to the drawings. Show it:

Fig. 6: a shoe sole with several attached to the outer surface

Pressure sensors. FIG. 1 shows a shoe sole S which has a plurality of sensors for measuring a pressure distribution. Here, the individual sensors SO, Sl, Sx are arranged flat in a plane, the present shoe sole assembly is equipped with a two-dimensional sensor layer.

FIG. 2 shows the arrangement according to the invention of a single layer of measuring sensors S00, SOI, SOn in a shoe sole S. It can be seen here that the present 8 × 16 matrix of pressure sensors requires only 8 lines on the right side and 16 lines on the lower side. This is possible due to the cross-connected pressure sensors, which also take up less space due to the cross-over connection. Thus, a higher resolution of the measuring range can be achieved due to a higher number of pressure sensors. In addition, different measuring ranges of individual sensors can be combined in such a way that several measuring ranges can be measured simultaneously at a certain pressure point.

It is possible that a built-in chip can only read out 8 force sensors at a maximum. Thus, groups of 8 sensors can be formed. However, these sensors are read one after the other. Moreover, it is particularly advantageous according to the invention that supply lines, ie, electrical conductor tracks can be saved in such a way that not every single pressure sensor has to be connected to a chip, but that, as shown in FIG. 2, only conductor tracks have to be removed from the respective outer pressure sensors ,

The solution according to the present invention measures the resistance or compensation of a voltage of two spaced-apart and electrically conductive tracks. However, the voltage must flow through an electrically conductive material. The resistance generated by the electrically conductive material is constant and can be defined specifically for the purpose of manufacture.

The upward inaccuracy curve of the measurement accuracy with increasing pressure can be supplemented or replaced by a further layer / semiconductor layer with a changed resistance value and the necessary electrical conductors as a sensor. If the carrier layer is divided into non-conductive strips in tiles, the problem of Creepage currents and short circuits are solved or reduced. Installing temperature sensors in a shoe sole is similar. Pressure differences also measure temperature differences on the sole of the foot.

One aspect of the present invention is the use of a logic of electrical connections in formers of a matrix within individual and also several superimposed layers, as described above.

The matrix allows the measurement or readout of a plurality of sensors, within defined time periods and levels, which are addressed in a circuit row by row and read out one after the other. The solution of a crossover (in series and parallel) saves connections to the microcontroller and cables on the board. Thus, smaller sizes, a lower weight, less energy and thus a lower production price are possible.

Depending on the required accuracy and measuring range, the layers can be activated and adjusted electronically autonomously. Each layer can measure different areas. Grades from different layers can be combined and a more accurate result can be measured even at high weights.

The matrix layer and surface sensor according to the invention is advantageous in terms of size, measuring range, accuracy, simplicity of manufacture, simplicity in the matrix, and software when measuring masses.

Figure 3 shows cross-arranged and connected strain sensors, which can be used as pressure sensors each one layer use. In the present FIG. 3, a cross-connected first strain-strip sensor is shown at the top left, which is produced by means of a crossover connection of strain sensors S00 and S001. Furthermore, a strain sensor of a second layer is shown, which has the two sensors S10 and Si l connected in cross-over. These two sensors can be installed in layers in such a way that the first sensor consisting of sensor unit S00 and sensor unit SOI is arranged in a layer and, above or below, the second sensor is provided consisting of first sensor unit S10 and second sensor unit Sil is. However, the subject matter of the present invention is by no means limited to strain gauge sensors.

4 shows a layer model of the shoe insole according to the invention, comprising the layers L0, LI, Lm. In the present FIG. 4, the individual sensors S00 to Smn are shown in a schematic representation. In a first layer L0, the sensors S00, SOI, ..., SOn are arranged. In the previous example, the pressure sensors of the first quantity are each arranged above or below the pressure sensors of the second quantity or of the further quantities. Thus, it is possible according to the invention to add up the measured values of the individual pressure sensors in such a way that an application of the total weight to a measured pressure point can be calculated. If, for example, in the present FIG. 4, one presses on the side of the shoe insole arranged on the left, then the measurement results of the sensors S00, S10, SmO are added up in such a way that the pressure point on the left side of the shoe sole is read out.

As can be seen in the present figure 4, any number of layers, each with a quantity of pressure sensors can be provided. In this case it is not necessary, but if appropriate advantageous that each layer L0, LI, Lm has the same number of pressure sensors.

The board is as a carrier or semiconductor layer simultaneously receiving unit of the electrical conductors. To apply further layers can be painted and / or coated. Even several layers processed on top of each other have only a height of less than 1 mm. The matrix operates three-dimensionally between the layers of the board according to one aspect. The matrix can also be used diagonally and / or across layers to improve performance.

FIG. 5 shows the layer model described in FIG. 4, ie the layer matrix in a three-dimensional representation, wherein the first index of each sensor indicates the horizontal position point within the layer, numbered from left to right in the present case. The second index indicates the arrangement of the respective pressure sensor in the horizontal depth plane of a layer of the shoe insole, in this case numbered from front to back. The third index indicates the layer numbering within the shoe insole, numbered from top to bottom here. Thus, in the present Figure 5, the foremost Pressure sensor of the uppermost layer left the indexing S000 and the pressure sensor of the lowest layer, right rear, the indexing Sxyz.

This makes it clear that the proposed layer model is a three-dimensional arrangement of sensors, which can also be individually addressed within this three-dimensional model. Thus, each individual pressure sensor within the three-dimensional shoe insole can be individually addressed or read or it can also be read in groups. This means that any subset of the provided pressure sensors can be read out. Thus, it is possible according to existing application scenarios, such as a particular sport to take into account.

On at least one carrier or semiconductor layer, an arbitrarily high number of sensors is directly applied and interconnected by means of cross-over connection (row and parallel) to reduce the connections of individual electronic sensor elements. This solution is particularly advantageous if the carrier or semiconductor layer is divided by non-electrically conductive strips in tiles. The sizes of the tiles are dimensioned so that the size of an electronic sensor element is optimized for the respective application. A crossover circuit (in series / parallel) allows the electronic feed and discharge lines of each individual carrier or semiconductor layer with interconnects to be reduced to approximately 20 percent compared to conventional solutions, without adversely affecting the measurement itself. At least one carrier or semiconductor layer produced with electronic interconnects as electronic sensor elements serves to measure the mass of a person. Each additional layer makes it possible to improve the measured results, such as higher and more accurate measurement results. Each semiconductor layer defines a specific measuring range for measuring ground and can be adapted for further applications. A semiconductor layer can measure the smallest differences in mass, for example in milligrams. Each additional semiconductor layer within a multilayer electronic sensor component preferably has at least the same range of the resistance value. Thus, at least twice the mass can be measured when added with the resistance value of the first layer.

When using different semiconductor layers with different resistance values, very high masses can be adapted and yet extremely accurately measured. If necessary For example, 8 layers of semiconductor and barrier layers, coated or painted, can be stacked. If required, the semiconductor and electrical sensory tracks can be designed as a cascade or avalanche structure.

The tiles and the electrical sensory tracks can be adapted to the desired application in size. Additional layers can be barrier layers that prevent leakage currents and thus contribute to the accuracy of the measurement results. Additional layers may also be cover layers which protect the individual electrical sensor component, or else the carrier or semiconductor layer, against external and internal stresses. Thus, the number of semiconductor and electrical sensory track tiles on the respective size of the board or the multilayer board and the mass to be measured can be differentiated and, if necessary, for example, cascaded produced. The board can be so completely in one operation, including other polymer or resistive layers, barrier or release and / or cover layers are made.

Individual layers can also be painted, powdered or powdered. The electronic unit is cascading capable of reading each required sensor separately or in combination also diagonally through the layers in order to be able to measure differentiated and extremely accurate values even at high weights. By diagonally measuring, for example, in the case of a shoe sole of a sprinter, a larger number of usable results can be determined with fast dynamic movements.

An encircling electrical trace, whether superimposed on one layer or multiple layers, can be used to solve the problem of measuring mass with electrical sensory trace tiles and semiconductor tiles. This circulating electrical conductor on the carrier or semiconductor layer is used, for example, for the transmission of information to the arithmetic unit.

5 shows a shoe sole S with a plurality of pressure sensors mounted on the outer surface according to an embodiment of the present invention. Thus, according to this embodiment, folded-up sections of the carrier material of the shoe sole S form the outer surface. The outer surface according to the invention, however, is not limited thereto and may be formed, for example, in one piece. On the outer surface are towards the horizontal portion 100 of the sole S showing several pressure sensors 101 attached. In the present embodiment, these pressure sensors 101 are designed to be single-layered. However, it is understood that a plurality of layers of pressure sensors 101 can also be arranged on the outer surface, as shown with reference to the exemplary embodiments mentioned above. The measurement of the forces occurring on the attached to the outer surface of sensors 101 makes it possible to make statements about how, for example, strong deceleration from the high acceleration particularly on non-yielding ground on the musculoskeletal system. In addition, foot deformities are detected not only in their vertical but also in their horizontal impact.

The horizontal part 100 of the shoe sole S or the remaining part of the shoe sole S may also have one or more pressure sensors. Thus, the shoe sole S, as explained above with reference to further embodiments, a first layer L0, LI, ..., Lz with a first set of cross-connected pressure sensors S000, ..., Sxyz, set up for weight measurement in a first measuring range have. In addition, for example, the horizontal part 100 of the shoe sole S at least a second layer L0, LI, ..., Lz with a second set of cross-connected pressure sensors S000, ..., Sxyz, set up for weight measurement in a second measuring range have.

According to the invention, a low-cost so-called low-energy microcontroller with storage and radio unit is installed on a carrier material for measurement and control.

According to the invention, the at least one sensor is located directly on the carrier material of the microcontroller and / or spaced apart on at least one further carrier material.

The sensor system measures at least one data record in real time at at least one measuring location and then stores it. The device according to the invention independently communicates with at least one further measuring location and can independently evaluate results and trigger actions, it can work independently in one example and / or it can be given tasks from the outside.

Individual and continuous data can be measured at at least one measuring location, at least one state and / or at least one state change and after determination and determination of the data, actions and reactions can be triggered, or the invention goes into a sleep mode until the next autonomous or externally triggered activation.

A further aspect of the present invention is given by the fact that the individual and continuous data from state and state change, in particular weight and weight change at at least one measurement site measured and stored and for a determination and activation of actions according to the respective special record after storage in a data storage be available for further processing.

A further aspect of the present invention is provided in that load intensities, for example by a constant or changed concentric and eccentric movement (waveform in time and lifting height) in the execution time and lifting height are determined.

In the following, aspects of the data technology implementation of the readout of the sensor values together with their transmission, storage and evaluation will be described. The cloud solution according to the invention is based on a combination of RESTful web services and NoSQL databases, which enables high scalability, system stability and, at the same time, independence from large cloud providers. A cloud can be present here as at least one arithmetic unit, which is addressed by means of a network. For example, a data center is suitable as a so-called cloud. However, this can also be a single local memory.

REST stands for Representational State Transfer and describes a concept for the development of service applications based on the functioning of the Internet. Individual resources are uniquely identified by a URI (Unique Resource Identifier) and provided for client applications. Client applications can create, retrieve, edit, or delete new resources using a limited set of commands borrowed from the HTTP command set (CRUD principle).

A resource itself is transferred from the server to the client prior to transmission and vice versa into a text-based representation. As a representation format, in one aspect of the present invention, JSON is used, which may be up to 30% reduced data volume and in addition can be directly interpreted as a Javascript code and read from any web browser and processed.

This combination of text-based data representation and access to resources via URIs and standardized HTTP commands enables both client applications developed specifically for this purpose, proprietary software, and a web browser that can be used on any Internet-enabled end device, such as a PC, a smartphone, a home computer Smart TV or similar devices, is available to communicate with the cloud, creating a reusable communication interface for all popular devices. In later development steps, an extension of the service landscape by new services is possible, which can interact with the previous services via this interface and thus can supplement additional functionality.

For the implementation of the web services, according to one aspect of the present invention, a stateless, ie stateless, approach is chosen. This type of implementation assumes that the service application is never informed of the state of the requesting client, except by the data that the client transmitted to the cloud along with the current request. This, in turn, makes it possible to view a request as a closed unit and thus allows the use of load balancers, which in turn can distribute the requests to any server system by using given metrics. This provides the cloud with the maximum horizontal scalability needed to handle the requests of potentially hundreds of thousands or even millions of clients, without jeopardizing the stability of the overall system or risking system slowdowns.

In one aspect of the present invention, this architecture is supported by the aforementioned NoSQL databases. Due to the expected amount of data, individual computers would quickly reach the limits of their performance. This also applies to conventional relational database systems, which are very well vertically, that means by an upgrade of the hardware built into the server, but only moderately to poor horizontally, that means by adding new servers, let scale. NoSQL databases are not subject to such limitations to the same extent, so the overhead of managing larger, horizontally scalable clusters is less than traditional relational databases. In addition, it comes to bear that more complex structures, such as resources, also called entities, can be mapped poorly via relational database systems. On the other hand, document-oriented NoSQL databases such as MongoDB are in a position to represent complex structures and objects quasi-natively and simplify the integration of the persistence layer into the business layer implemented in the services.

In data storage, a distinction must be made between clearly personal and only indirectly personal data. Clearly person-related, profiles are for example the data such as first and last name, address data, birthday, etc., indirectly personal data are the data collected by measurements and / or surveys. The acquired data is broken down into measurements, waves and segments according to one aspect of the present invention. Where a measurement contains at least one wave and additional meta information such as tags. A wave is a collection of multiple segments that collect the raw data of the wave and summarize other meta information such as eccentric phase, time, etc. for that portion of the measurement.

The measurements are supplemented by surveys that provide information about the condition of the users and thus give conclusions about the fitness level and finally special features in the measurement data.

Since personal data must be specially protected to meet standards such as HIPAA or HITECH, these are stored separately from the rest of the data in separate databases. There, according to one aspect of the present invention, these are stored in encrypted form and thus protected separately, while the indirect data can not be unambiguously assigned without access to the personal databases and therefore do not allow any conclusions to be drawn to individual users and do not need to be encrypted separately.

Streaming services should be used to transfer the metrics to the cloud services. The data fed in there are, in accordance with one aspect of the present invention, analyzed, preprocessed and filtered in real time by algorithms designed for this purpose. In the analysis of the data streams algorithms could find application on Knowledge of neural network research or originate from the field of pattern recognition and are designed specifically for the processing of streams and maximum scalability.

Thus, according to one aspect of the present invention, abnormalities are to be detected and forwarded via push notification services to third parties (for example, relatives, doctors or trainers and other caregivers).

In addition, the amount of data to be stored can be reduced many times by discarding measurement data which has no abnormalities and extracting from the raw data the meta data relevant for the end user or adding meta data necessary for later analysis ,

This meta-information could be used to target audience-oriented investigations over predefined time periods. The corresponding meta-information, which uniquely identifies these target groups, is appended to the recorded datasets, enabling later separate Big Data analysis or testing of newer and improved algorithms.

Once the analysis and testing has been completed, the raw data can be combined into larger data chunks through meta-information and compressed compression can be used to further reduce the amount of data and then archive the chunks to dedicated data stores.

In addition, the use of graph-oriented databases in the context of sociological aspects could open up new queries and uses. Analyzes could be carried out in relation to friends, acquaintances or job profiles in order to be able to understand to what extent the improvement of the fitness of individuals has an effect on other people in their circles, or whether certain occupational groups have a particular inclination to particular posture errors or favor them.

Another aspect is queries that compare one's own performance with the average performance in the immediate environment. Such aspects could contribute to spatial-specific, geospatial, analyzes and health / fitness maps and improve their accuracy.

The data processing of the values determined according to the invention is an aspect of the present invention, since units are addressed in a new way. Thus, according to the invention, concepts of data processing can be ported to the fitness area.

The present invention is not generally limited to a shoe sole, a shoe insole and a shoe. Also advantageous is an analog configured sock. Thus, all aspects cited for a shoe sole, a shoe insole and a shoe can also be applied to a sock. Further features of this sock can be found analogously to the subclaims.

For example, a sock proposed for measuring body weight, having a first layer comprising a first set of cross-connected pressure sensors arranged for weight measurement in a first measurement range; and at least one second layer comprising a second set of cross-connected pressure sensors arranged for weight measurement in a second measuring range.

Also advantageous is an analog ausgestalteter glove. Thus, all aspects cited for a shoe sole, a shoe insole and a shoe can also be applied to a glove. Other features of this glove are shown in the dependent claims.

For example, a glove is proposed for measuring weight with a first layer comprising a first set of cross-connected pressure sensors arranged for weight measurement in a first measurement range; and at least one second layer comprising a second set of cross-connected pressure sensors arranged for weight measurement in a second measuring range.

According to a further embodiment, at least one further mass sensor is provided which, for example, measures the pulse waves, which result from cardiac activities, on the vessels of the foot, determines the vessel state by means of pulse wave velocity PWG and / or determines the pulse wave transit time PWL. Due to the design and the size of the mass sensor, the sensors can be used in many areas of the body. Prerequisite for their use is that the pulse waves are noticeable or detectable.

At a single measuring point, the pulse or the distance between two heartbeats can be measured. The pulse wave transit time and thus the pulse wave velocity can be measured at two measuring points which run away from one another and from the heart and are connected above the skin and on the vessel. From the pulse wave velocity, the continuous blood pressure can be determined after a calibration.

For the implementation of measuring the weight under the foot only an additional component with respect to further embodiments is required. For implementation, a 16-bit transducer with a polymer can be used to measure the mass. Different polymers than semiconductors and thus different resistances are also suitable as converters.

A tab as a soft board, which is formed by the foot sensor or only a cable which is guided to the sensor or the sensors on the instep, can be used. The system can thus be manufactured in one piece and provides a vital data measurement.

According to a further embodiment, the mass sensor is designed as a pressure sensor and thus measures the pressure at at least one vessel.

A measurement of vital data from one and / or two measurement points works according to a further embodiment with mass sensors.
