Description

The invention relates to methods for producing a conductor unit with sensors for connection to a data processing system interconnected to an electromagnetic wave transmitter / receiver and an energy source of a sole body for use as an insole for detecting biophysical measurements in a shoe and guide units of an insole for detecting biophysical measurements in shoes having sensors for connection to a data processing system in conjunction with an electromagnetic wave transmitter / receiver and an energy source of a sole body.

Biophysical measures measured in shoes can be used, among other things, to detect harmful pressure loads and to carry out movement analyzes in the fields of orthopedics and sports.

Thus, the document discloses DE 10 2014 008 091 A1 a device for detecting pressure loads and / or temperature differences in a pair of insole for the diabetic foot, which consists of a combination of in a sole pair of soles with incorporated textile, capacitive pressure sensors and soles with incorporated temperature sensors. The soles can be designed as sole composite. The textile pressure sensors consist of two opposing sensor surfaces. The temperature sensors are incorporated in one of the soles. The electrical conductors are realized by means of textile processing methods, which will not be discussed in more detail.

The publication DE 10 2010 049 154 A1 discloses a sole with sensor having sensors and electronics for measuring the mechanical pressure distribution on the human foot. The sensors and the electronics are arranged on a circuit board. In addition, the sensors can also be connected to the board. The sole is limited to measuring the pressure.

The publication US 4,647,918 A describes a device for detecting the pressure load at several points of the foot. For this a shoe insert with several pressure sensors is used. The pressure sensors are placed at different points of the foot. Signaling takes place by means of a device which, on the one hand, is connected to the sensors and, on the other hand, is portable by the patient. The evaluation is carried out on a time-related basis via a microprocessor, which is electrically conductively connected to the transducers via a cable harness, in accordance with predetermined and stored limit values. A light source is used, for example, the signaling. The cable harness must be guided from the shoe insert over the shoe and leg to the device. It can not be ruled out by the cable caused and not certain pressure loads on the foot. Especially in the movement, this can rub in the shoe on the foot and cause injury. This can only be avoided by special measures in the footwear.

Through the publication DE 103 14 211 A1 For example, a pressure-sensitive stocking having a pressure-sensitive material is known. This captures a pressure exerted on the stocking. On the one hand, the pressure-sensitive material contains threads whose electrical resistance is pressure-dependent. On the other hand, the pressure-sensitive material contains electrically conductive threads that touch each other, wherein the electrical contact resistance between each two touching threads is pressure-dependent. For the recording and signaling of the pressure, a selection of the pressure measuring points in the textile is to be made. Due to the multitude of crossing points, this is not easy to realize.

The indicated in the claims 1 and 2 invention has for its object to provide an insole for detecting biophysical measurements so that it offers the user a high level of comfort, easy to manufacture and due to the materials used and realization has a long life.

In a first embodiment, the electrical conductors can be produced by cutting through an electrically conductive textile applied to the carrier. For this purpose, the electrically conductive textile is applied to the carrier as an electrically non-conductive textile. This can be done by gluing, laminating or laminating. Subsequently, this electrically conductive textile is cut through, so that printed conductors are formed. The wearer will not be cut. The electrically conductive material between the tracks may then be removed, also referred to as de-icing

In a second embodiment, the carrier is printed as electrically non-conductive textile with electrical conductors as conductor tracks. This can be done for example with electrically conductive paint or electrically conductive plastic. After drying and / or curing, the electrical conductors are realized.

In a third embodiment, the electrically non-conductive textile can be embroidered with thread-like electrical conductors so that the filamentary electrical conductors are conductor tracks in and on the carrier. The threads can also be ribbons.

Of course, the electrical conductors may also be implemented by a combination of the three embodiments.
