Description

Intelligent insole with multiple sensors and health management system applying intelligent insole
Technical Field
The invention relates to the field of intelligent insoles, in particular to an intelligent insole with multiple sensors and a health management system applying the intelligent insole.
Background
In modern society, general people wear shoes every day for a long time, and the shoes can be matched with each other when going out, working, doing sports and the like, and the shoes mainly aim at protecting the safety of feet besides the beautiful purpose. For example, shoes with different functions can be worn for different activities such as walking, running, mountain climbing and the like, so that the feet can be properly assisted and protected during the activities. Meanwhile, the state of the foot, especially the state of the sole of the foot, can often reflect the health state of a person, and the selection of correct shoes is an indispensable part in life.
However, most shoes are in a relatively airtight and non-ventilated state after being worn, and in addition, the action of the feet can cause sweating to raise moisture no matter walking or sports, so that bacteria or mold are easily grown in a continuous warm and humid environment to affect the health of the feet. Moreover, the shape of the sole of each person is different, and the same shoe template cannot be suitable for the foot shape of all persons, so that if the shoes are worn for a long time, the problems of foot deformation or uneven stress and the like can be caused. Therefore, many people replace the original shoe with a new insole, such as a special material or a special design insole, in order to improve the above-mentioned problems.
However, the general insole can only improve part of the problems, and when the shoe is worn for a long time, a general person usually cannot notice whether the distribution state of the pressure on the sole of the foot is normal or not, or cannot notice the rise of the temperature and humidity in the shoe, and when the problem really occurs, the general person often causes health damage and cannot recover. The research aiming at the intelligent insole in China is less, the sole function partition is mainly optimized from sole pressure distribution, for example, Seatting and other people utilize the intelligent insole to perform the research of optimizing shock absorption on the insole (Seattng, Tanghong, Wang Fang. the research of the intelligent pressure shock absorption insole [ J ]. Shanghai textile science and technology, 2019,47(10): 33-35.). Heyali et al used orthopedic insoles to predict the conditions that would be caused in an abnormal situation and adopted appropriate corrective measures (Heyali, Wang east. application of orthopedic insoles in rehabilitation of related conditions research status J. China J. Med. 2017,36(05): 460-. However, studies on the influence of temperature and humidity on the sole of a foot are relatively lacking. Therefore, the inventor of the present invention has designed an intelligent insole to solve the above problems, and has improved the disadvantages of the prior art, thereby realizing industrial implementation and utilization.
Disclosure of Invention
In view of the above problems, the present invention provides a smart insole with multiple sensors, and more particularly, to a smart insole with pressure, temperature and humidity sensors, which can display the pressure, temperature and humidity of the foot, and further provide health care advice, and a health management system using the smart insole with multiple sensors.
The object of the present invention is achieved at least by the following means.
A smart insole with multiple sensors comprises an insole body, a pressure sensor, a temperature sensor, a humidity sensor, a signal collector and a wire. The pressure sensor, the temperature sensor and the humidity sensor are arranged on the surface of the insole body, and the pressure sensor is arranged at the position where the insole body is contacted with the foot, such as the position of the insole corresponding to the toe, forefoot, midfoot and heel areas of the foot, and is used for obtaining a pressure signal of the insole body contacted with the foot; the temperature sensor and the humidity sensor are arranged at the position which is not contacted with the foot on the insole body, such as the position of the insole corresponding to the arch area of the foot, and are used for obtaining a temperature signal and a humidity signal of the insole body; the signal collector is arranged on the surface of the insole body, is electrically connected to the pressure sensor, the temperature sensor and the humidity sensor through wires, and is used for receiving the pressure signal, the temperature signal and the humidity signal and sending the pressure signal, the temperature signal and the humidity signal to the signal receiver in a wireless transmission mode; the conducting wires are arranged on the surface of the insole body and used for connecting the three sensors and the signal collector.
Furthermore, the pressure sensor detects the potential change caused when the foot applies force on the insole body, namely the magnitude of the potential difference, so as to detect the pressure state, and obtain the pressure signal of the insole body contacting with the foot; the temperature sensor and the humidity sensor are provided with resistors with temperature coefficients and humidity coefficients, and the temperature and humidity states of the insole body are detected by using the change of the resistance values so as to obtain temperature signals and humidity signals of the insole body.
Further, the pressure sensor, the temperature sensor, the humidity sensor and the insole body are manufactured in the same 3D printing process, so that manufacturing procedures are reduced, and manufacturing quality such as sensor attaching degree is improved.
Further, the signal collector is a transceiver with one or more wireless communication modules of Bluetooth, Wi-Fi and RFID.
Further, the thickness, the length and the width of the insole body are determined according to the shape information design drawing of different crowds; the insole body is made of one of synthetic vinyl resin (EVA) and Polyurethane (PU).
Furthermore, the pressure sensor, the temperature sensor and the humidity sensor are all in a miniaturized circuit structure; the thicknesses of the pressure sensor, the temperature sensor and the humidity sensor are all between 0.001 mm and 0.003 mm; the areas of the pressure sensor, the temperature sensor and the humidity sensor are all between 2mm and 8mm2To (c) to (d); the distance interval between every two sensors is 5-15 mm, the number of the pressure sensors, the temperature sensors and the humidity sensors is adjusted according to the size of insoles of different users, and the number of the pressure sensors, the temperature sensors and the humidity sensors is 15-25; the pressure sensor, the temperature sensor and the humidity sensor are made of one of metal conductive materials or piezoelectric materials.
Because the thickness of each sensor is obviously less than that of the existing sensor, even if the sensors are formed on the surface of the insole body, the insole is not provided with a convex foreign body feeling when being worn, and the sensors are not required to be arranged on the insole body by designing a groove during manufacturing, so that the insole is superior to the existing insole with a sensing device in comfort and durability.
A health management system comprises a smart insole, a signal receiver and a cloud server; the intelligent insole comprises a pressure sensor, a temperature sensor, a humidity sensor and a signal collector; the signal receiver comprises a display, a wireless communication module and a health management application module; the signal collector receives pressure signals, temperature signals and humidity signals sensed by the pressure sensor, the temperature sensor and the humidity sensor and sends the pressure signals, the temperature signals and the humidity signals to the wireless communication module in a wireless transmission mode, and the health management application module converts the received pressure signals, temperature signals and humidity signals into sensing numerical values of actual pressure, temperature and humidity and presents the sensing numerical values through the display; the health management application module uploads the sensing signal to a cloud server through a wireless network and stores the sensing signal in a database of a cloud; the cloud database provides corresponding diagnosis suggestions according to the uploaded sensing signals, and the corresponding diagnosis suggestions are transmitted back to the health management application module and displayed on the display.
Further, the signal receiver is a handheld mobile device, such as a smart phone, a tablet computer, a notebook computer, etc.
Further, the health management application module sets critical values of various states, such as an upper pressure limit value, an upper temperature limit value or an upper humidity limit value, and when the sensed value exceeds the critical value at a certain moment or exceeds an average value within a predetermined period of time, the display displays a warning message; for example, when the received signal shows that the foot pressure exceeds the average pressure value within the default time, the display displays a warning message to remind the user that the insole supports the foot pressure for a long time and needs to sit down or relax; for example, when the sensed temperature value exceeds the upper temperature limit value, the user is informed that the user needs to take off the shoes for ventilation.
The above settings are all set to avoid the health problems caused by the temperature and humidity rising caused by long-time walking or pressing on the feet or long-time wearing of shoes.
Furthermore, the cloud server sets corresponding diagnosis suggestions for the sensing results, and when the pressure signals, the temperature signals and the humidity signals uploaded by the health management application module are received, the cloud server can compare the built-in mode rules to provide corresponding diagnosis suggestions.
Compared with the prior art, the invention has the following advantages:
(1) according to the intelligent insole, the insole body, the pressure sensor, the temperature sensor and the humidity sensor are formed on the surface of the insole body in a 3D printing mode, so that the manufacturing steps of the insole are reduced, and the quality of a finished product is improved.
(2) The pressure sensor, the temperature sensor and the humidity sensor of the intelligent insole are miniature sensors, the thickness of the intelligent insole is thinner than that of a conventional sensor, foreign body sensation cannot be caused when the intelligent insole is worn, and the comfort is improved. Meanwhile, the arrangement of an excessively protruding sensor is also avoided, and the durability of the insole is reduced after contact friction.
(3) The intelligent insole of the invention can transmit the sensed pressure signal, temperature signal and humidity signal to the signal receiver, and compare the signal with the critical value to determine whether the signal is abnormal or not and select whether to send out a warning message or not. The data can be uploaded to a cloud server and compared with the normal model to obtain a corresponding diagnosis suggestion, so that a proper health care suggestion is obtained in real time, and the practicability of the intelligent insole is effectively improved.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention are described in detail below with reference to the accompanying drawings.
Example (b):
as shown in FIG. 1a, a smart insole with multiple sensors comprises an insole body 11, a pressure sensor 13, a temperature sensor 14, a humidity sensor 15, a signal collector 16 and a lead 17. The pressure sensor 13, the temperature sensor 14 and the humidity sensor 15 are arranged on the surface 12 of the insole body 11, and the pressure sensor 13 is arranged at a position where the insole body 11 contacts with the foot, such as an insole position corresponding to toe, forefoot, midfoot and heel areas of the foot, and is used for obtaining a pressure signal of the insole body 11 contacting with the foot; the temperature sensor 14 and the humidity sensor 15 are disposed at a position on the insole body 11 not contacting with the foot, such as an insole position corresponding to an arch region of the foot, for obtaining a temperature signal and a humidity signal of the insole body 11; the signal collector 16 is arranged on the surface 12 of the insole body 11, is electrically connected to the pressure sensor 13, the temperature sensor 14 and the humidity sensor 15 through a wire 17, and is used for receiving the pressure signal, the temperature signal and the humidity signal and sending the pressure signal, the temperature signal and the humidity signal to the signal receiver 30 in a wireless transmission manner; the conducting wires 17 are arranged on the surface 12 of the insole body 11 and are used for connecting the three sensors and the signal collector 16.
Further, the pressure sensor 13 detects a pressure state by detecting a potential change, i.e., a magnitude of a potential difference, caused when the foot applies a force to the insole body 11, so as to obtain a pressure signal of the insole body 11 contacting the foot; the temperature sensor 14 and the humidity sensor 15 are provided with resistors with temperature coefficient and humidity coefficient, and the temperature and humidity state of the insole body 11 is detected by the change of the resistance value, so as to obtain the temperature signal and the humidity signal of the insole body 11.
Further, the pressure sensor 13, the temperature sensor 14, the humidity sensor 15 and the insole body 11 are manufactured in the same 3D printing process, so as to reduce the manufacturing procedures and improve the manufacturing quality such as the sensor attaching degree.
The conducting wire 17 and the sensor can be formed on the surface 12 of the insole body 11 in the 3D printing process at the same time, and the conducting wire 17 can also be formed on the surface 12 of the insole body 11 without causing discomfort in wearing because the conducting wire 17 and the sensor have similar materials and thicknesses.
Further, the signal collector 16 is a transceiver having one or more wireless communication modules of bluetooth, Wi-Fi, and RFID.
Further, the thickness, length and width of the insole body 11 are determined according to the shape information design drawing of different people; the insole body 11 is made of one of synthetic Ethylene Vinyl Acetate (EVA) and Polyurethane (PU)
Further, the pressure sensor 13, the temperature sensor 14 and the humidity sensor 15 are all of a miniaturized circuit structure; the thicknesses of the pressure sensor 13, the temperature sensor 14 and the humidity sensor 15 are all between 0.001 mm and 0.003 mm; the areas of the pressure sensor 13, the temperature sensor 14 and the humidity sensor 15 are all between 2mm and 8mm2To (c) to (d); in the embodiment, the length, the width and the thickness of each sensor are respectively 1mm, 3mm and 0.02 mm; because the thickness is obviously smaller than the existing sensor, even if the sensor is formed on the surface 12 of the insole body 11, the sensor can not be placed in the groove on the insole body 11 during the manufacturing process, and the sensor is superior to the existing insole with the sensing device in terms of comfort and durability.
As shown in fig. 1a, the distance interval between each sensor is 5-15 mm, and the number of the temperature sensors 14 and the humidity sensors 15 is not limited to 1 in fig. 1 a; as shown in FIG. 1b, the number of the pressure sensors 13, the temperature sensors 14 and the humidity sensors 15 is adjusted according to the size of the insole of different users, and the number is about 15-25.
The pressure sensor 13, the temperature sensor 14 and the humidity sensor 15 are made of one of a metal conductive material and a piezoelectric material.
As shown in fig. 2, a health management system includes a smart insole 10, a signal receiver 30 and a cloud server 40; the intelligent insole comprises a pressure sensor 13, a temperature sensor 14, a humidity sensor 15 and a signal collector 16; the signal receiver 30 comprises a display 31, a wireless communication module 32 and a health management application module 33; the signal collector 16 receives the pressure signal, the temperature signal and the humidity signal sensed by the pressure sensor 13, the temperature sensor 14 and the humidity sensor 15 and sends the signals to the wireless communication module 32 in a wireless transmission manner, and the health management application module 33 converts the received pressure signal, temperature signal and humidity signal into sensing values of actual pressure, temperature and humidity and presents the sensing values through the display 31; the health management application module 33 uploads the sensing signal to the cloud server 40 through the wireless network and stores the sensing signal in the cloud database; the cloud database provides corresponding diagnosis advice 41 according to the uploaded sensing signal and transmits the diagnosis advice back to the health management application module 33 and presents the diagnosis advice on the display 31.
Therefore, the user can know the real-time state of the intelligent insole, namely the real-time state of the foot, by only opening the health management application module 33 at any time.
Further, the signal receiver 30 is a handheld mobile device, such as a smart phone, a tablet computer, a notebook computer, etc.
Further, the health management application module 33 sets a threshold value of each state, such as an upper pressure limit, an upper temperature limit or an upper humidity limit, and the display 31 displays a warning message when the sensed value exceeds the threshold value at a moment or exceeds an average value within a predetermined period of time; for example, when the received signal indicates that the foot pressure exceeds the average pressure value within the default time, the display 31 displays a warning message to remind the user that the insole supports the foot pressure for a long time and needs to sit down or relax; for example, when the sensed temperature value exceeds the upper temperature limit value, the user is informed that the user needs to take off the shoes for ventilation.
The above settings are all set to avoid the health problems caused by the temperature and humidity rising caused by long-time walking or pressing on the feet or long-time wearing of shoes.
Further, as shown in fig. 3, the cloud server 40 sets a corresponding diagnosis suggestion 41 for the sensing result 43, and when receiving the pressure signal, the temperature signal and the humidity signal uploaded by the health management application module 33, the cloud server 40 may compare the built-in mode rule to provide the corresponding diagnosis suggestion 41.
As shown in fig. 3, in the present embodiment, the pressure signal, the temperature signal and the humidity signal detected by the sensor are transmitted to the signal receiver 30 in a wireless transmission manner; the signal receiver 30 is a smart phone, and converts the sensing signal into an actual pressure distribution map and a temperature and humidity value through a health management application module 33 in the smart phone, and the actual pressure distribution map and the temperature and humidity value are displayed on a display 31 of the smart phone for a user to view. If the temperature and humidity value exceeds a threshold value, such as the humidity exceeds 60% or the temperature exceeds 25 ℃, the signal receiver 30 uses a mobile phone ring or vibration to notify the user of the warning message.
The signal receiver 30 uploads the pressure distribution diagram and the temperature and humidity values to the cloud server 40 at regular time, and in addition to storing and recording the sensing result 43 in the cloud, the real-time sensing result 43 can be compared with the pre-stored normal model 42, and the comparison result is transmitted back to the signal receiver 30 according to the corresponding diagnosis suggestion 41, so that the user can obtain the suggestion for the foot health care in real time. For example, the pressure distribution patterns of the left foot and the right foot are not consistent, and the stress on the two feet is possibly uneven; if the pressure in a single area (forefoot or heel) is too high, there may be a dragging or step discrepancy, and it is recommended that the walking posture be adjusted to correct the step.
Since there may be a lot of types of foot problems, the types of pressure profiles are also many, and the processing operations required for comparison are not suitable for being performed on a typical handheld mobile device, so the diagnosis advice 41 is sent to the handheld mobile device for presentation after the cloud server 40 performs the operations.
For example, the collected pressure distribution can indicate the center of pressure (Central of pressure), and determine whether the center of the user is shifted when standing, and if the center is shifted to the medial side or the lateral side, the ankle is prone to be turned inwards or outwards. For example, when a normal person walks, the maximum pressure occurs in the metatarsal region and the heel region, but if the user has a diseased foot or has a poor walking posture, the pressure is likely to be transferred to the inner side or the outer side of the foot (such as the outer arch region), and a higher pressure region (for example, red color is displayed) is formed, and the judgment of the abnormal distribution of the pressure can prompt the user to shift the balance of the walking posture to the right or left, resulting in pressure concentration.
If a plantar pressure profile such as that shown in fig. 3 is collected, the health management system will suggest several recommendations as follows:
1. the poor use degree of the toe heads of the left foot and the right foot, especially the ring toe and the little toe, can cause the reason that the rear two toe heads float up and can not contact the ground and the walking balance degree is also poor because the feet of the user tend to be in the inner side when the user walks;
2. the pressure of the left big toe is slightly higher, which is likely to cause pressure of a single point, resulting in foot lesions such as corns. Therefore, the user is reminded to adjust and improve the correct walking posture, and the continuous aggravation of the injury is avoided.
The invention has certain difference with the prior art, and is embodied in that the invention customizes corresponding solutions according to the requirements of different audiences. I.e. the user can select the desired function on the handheld mobile device according to different needs, the diagnostic advice 41 given by the health management system is personalized to the opinion.
The invention considers two functions of preventing and improving foot diseases and correcting walking posture. For example, if the user is a diabetic foot, as shown in fig. 4b, the patient is emphatically reminded to take sedentary rest, ventilate the feet, clean the feet and provide cleaning skills; if the user is a teenager in the development stage, as shown in fig. 4a, the stress condition of the foot is mainly analyzed, the wrong walking posture is corrected, and the series posture problems of humpback, forward-leaning pelvis, false crotch width and the like are avoided.
The basis for dividing the function categories is as follows: if the user's needs are not met, it is not harmed significantly. For example, corn patients are painful due to abnormal rubbing and compression of the feet; if the diabetic foot patient does not take timely measures, ulcer can be caused, and amputation can be caused seriously; for general people, the good walking posture can help to correct the problem of poor posture, and the walking chair can have better posture and quality. Therefore, all the requirements related to foot diseases and influencing normal life can be classified into the first category of functions; the second function is the function of correcting walking posture, and the function has no great influence on normal life.
Firstly, the user selects the function according to the requirements of improving, preventing foot diseases or correcting postures, then the intelligent insole 10 is put into the shoe, and in the walking process, the signal receiver 30 receives the transmitted signal and makes different responses according to the user behaviors. As shown in fig. 4a, if the user needs to correct posture, and humpback occurs during walking, the health management application module 33 determines that the foot pressure distribution is inconsistent with the standard pressure distribution within a period of time, and sends out an alarm signal to remind the user that he should raise his head and lift his chest; as shown in fig. 4b, if the user is a diabetic foot patient, and stands or walks for a long time, the health management application module 33 determines that the foot pressure exceeds the preset pressure peak value within a certain period of time, and sends out an alarm signal to remind the user to sit down for rest.
