Description

The present invention relates to functional clothing with a tactile stimulus module and EMG electrode.

From the prior art devices for measuring electrical muscle activity are well known. With the help of needle or fine wire electrodes, such measurements can be made with very high precision. The use of surface electrodes also allows the determination of muscle activity. The measurement technique as such is called electromyography (EMG). Depending on the type of electrode used, a distinction is made between surface EMG and intramuscular EMG.

Furthermore, methods are known from the prior art, which allow the stimulation of body parts, especially skin and / or muscles.

In the DE 10 2014 110 476.5 For example, the applicant has disclosed a navigation method and a navigation system for transmitting tactile instructions to a human body, wherein the tactile instructions are determined by tactile stimulus modules. It is also called a sensor that is supposed to determine states of the user.

In particular, the electrical stimulation of muscles (EMS) is already used:
In the DE 20 2011 109 226 U1 discloses a mobile training system for electrical muscle stimulation (EMS), wherein this has a garment with at least one contact electrode for contact with the skin in the region of the muscle parts to be stimulated.

In the DE 10 2007 046 886 B4 discloses an EMS electrode for applying electrical current to the human body for purposes of EMS training, wherein the electrode is formed as a sheet pad having a highly conductive, flexible conductive layer.

In the DE 10 2010 052 710 A1 An EMS device for electrical muscle stimulation is described. This comprises an electrical control and an electrical pulse generator, to which at least two pairs of electrodes are connected via two cables in each case, wherein the electrodes are arranged at a distance from one another on the skin of a human being.

The combination of electromyography (EMG) with electrical stimulation of muscles (EMS) is also disclosed in the prior art.

The US 4,811,742 discloses a device that sends EMS signals to a muscle, with an EMG measurement being made in close proximity. It is disclosed that the EMS signal should be proportional to the signal strength of the EMG measurement. The invention is intended to increase the control of the muscles if it is impaired due to illness.

In the US 2003/0208246 A1 It is also about restoring the natural movement of muscles. An EMG pulse of a muscle is measured, compared with a limit value and possibly transmit an electrical pulse that is stronger than the received pulse. The same electrode pair can be used for measurement and transmission.

The US 5,549,656 A discloses a system comprising an electromuscular stimulator which transmits pulses into the skin and a two-channel electromyograph which detects signals generated in the muscle.

The US 2005/0113883 A1 relates to a method in which a user's attempt to activate a muscle is detected by means of an EMG sensor and an electrical signal is sent to the muscle when a limit value is exceeded.

The US 11 / 968,255 discloses a system for muscle rehabilitation, which includes EMG sensors placed in the vicinity of a muscle, wherein a processor receives the measured EMG signal and an electrical stimulation signal is delivered when certain EMG signal parameters are met.

The WO 2015 003 203 A1 discloses an electrical device having a voltage source for generating electrical stimulation signals and an EMG processor capable of receiving EMG signals. Here, a mode of the device is provided, in which EMG measurements and stimulation occur simultaneously.

A disadvantage of the prior art results from the fact that it is usually stationary systems, which are perceived as disturbing in the use.

The object of the present invention is to provide a tactile sensor device which can be used by the user without specialist or expert assistance.

Further, it is an object of the present invention to provide systems which make it allow to collect information about the wearer of the systems and to send information to the wearer of the protection systems, in particular this concerns protection system for dangerous situations.

This also has the advantage that the contact unit can not accidentally come off. If the contact unit is detachably connected to the first textile, this is more difficult, but the solubility has the advantage that an exchange of contact units, in particular for maintenance, cleaning and / or repair is particularly easy. Also, the cleaning of the functional clothing is simplified to a considerable extent. In particular, under the conditions of a washing process at elevated temperature, it may be advisable to remove any existing contact units of the clothing.

According to the invention, embodiments are particularly preferred when the functional clothing is autonomous. Autonomous in the sense of the present invention means that the functional clothing, in particular the functional clothing contact unit, does not require a permanent, wired connection to external energy storage or data processing devices for their functionality, in particular with regard to stimulus transmission and EMG measurement. However, this does not exclude that the functional clothing can be temporarily connected to a cable, for example, to recharge the energy storage.

The above embodiment allows feedback between the user and the virtual world or the avatar (eg, a virtual trainer) of the virtual world. If, for example, you are hit by a munitions bullet in a computer game, a haptic feedback can occur, for. As a vibration signal or an electrical pulse.

In a further embodiment, it is preferred if the contact surface forms or comprises an electrode or is part of the same. Preferably, this is the EMG electrode and / or the EMS electrode, particularly preferably both EMG electrode and EMS electrode. Furthermore, it is preferred if the contact surface comprises, is or is part of the tactile stimulus module, in particular if it is a tactile stimulus module in the form of an EMS electrode. It is also preferred that even if the tactile stimulus module is not part of the contact surface, there is at least one direct connection to the stimulus module. Immediately means preferably that the stimulus module is in direct contact with the contact surface.

It is particularly preferred if the display is an LED display, in particular an OLED display, which is controlled by the second internal data processing device, wherein the second internal data processing device is designed and is set up to control the tactile stimulus modules.

Further, a pain suppressing system comprising a functional garment as described above is the subject of the invention. In this case, in a pain, which is detected for example by the first sensor, the stimulus module is activated. In one embodiment, this transmits electrical stimuli which relieve the pain. Electrical stimuli are thought to be sent to the spinal cord by stimulation of tissue nerves, which attenuate the signal transmission of pain and / or cause the release of chemical substances in the brain that reduce pain perception. Even a stimulus module, which exerts pressure or gives off the heat, can reduce the pain. The pain relief probably underlying effect was first in " Pain Mechanisms: A New Theory, Ronald Melzack and Patrick D. Wall, Science, 1965, 150 (3699), 971-979. "Described. In the end, the stimulus triggered by the stimulus module (not or less painful) superimposes the stimulus that is perceived as painful, which is to be counteracted. Stimulus pathways of the central nervous system for transmitting the pain stimulus from the periphery to the brain are thereby influenced so that the pain transmission to the brain is reduced or prevented. The stimulation by current pulses for pain relief, for example, in the US 3817254 A described, where an automatic detection of the pain is not possible. The suitability of current pulses for the suppression of musculoskeletal pain was described in " M. Johnson, M.Martinson, Efficacy of mechanical nerve stimulation for chronic musculoskeletal pain: A meta-analysis of randomized controlled trials, Pain, 2007, 130 (1-2): 157-165. "Proved. The system is suitable for both acute and chronic pain. In the present case, however, in particular in connection with musculoskeletal pain, for example back pain, a system is provided which is suitable, in particular by means of the first sensor, to recognize in which areas and / or at what time active pain suppression is required. Especially for patients who can not comment and / or who are not subject to constant care, this can be advantageous.

By the present invention, a functional clothing is provided which can transmit stimuli to body parts. In one embodiment, electrical impulses are transmitted to muscle parts, causing the muscle or muscles to contract. In this case, an individual adaptation of the electrical impulses or the vibrations to the locally present muscular load is possible. In another embodiment, vibrations are transmitted to the skin surface, so that it experiences a stimulus and is preferably also heated. Numerous fields of application are conceivable here. For example, the functional clothing can make it possible for the user to be given instructions for a movement sequence. This allows athletes to intuitively learn specific difficult movements based on immediately perceived stimulus stimulation. A trainer can use the clothing available to transmit instructions while keeping track of whether or not they are being followed. It is also conceivable that instructions can be transmitted in dangerous situations. In some embodiments, by transmitting electrical pulses, it can be ensured that the muscles can be controlled according to the instruction instructions (regardless of the conscious control of body movement by the user). This can be particularly advantageous in hazardous situations, which require a particularly fast response. A particular concern of the present invention is also to be able to transmit stimuli in virtual environments depending on the muscle activity of the user. In this case, it is possible, for example, for a virtual avatar in a virtual environment to simulate analogous muscle contractions as actually performed by the user. Also stimuli of the virtual world can be simulated by stimulus transmission by means of the tactile stimulus modules. For example, if a player hits a virtual edge of a table with his or her arm, a muscular contraction or vibration can be caused on his or her arm.
