- the controller 4 may comprise, for example, a power unit for generating a stimulation pulse and a plurality of switches, such as e.g. Relays that distribute the stimulation pulses to the individual electrodes. Since the pacing pulses are relatively short for each individual electrode, the time between two pulses from the same electrode can be used to provide several other electrodes with their pacing pulses.
- a sensor 3 is assigned to each electrode 8.
- the sensor 3 is connected in each case via a control conductor 19 for signal transmission to the controller 4.
- the sensors 3 can in a preferred Embodiment be resistance sensors that recognize, for example via the conductivity, whether there is a good contact between the associated electrode 8 and the skin. In the case where there is no good contact, the stimulation pulse can be amplified.
- the associated electrode 8 itself take over the function of the sensor. In this case, as already mentioned above, the electrode 8 may be divided into two and used in different operating modes. In the operation of electrostimulation, the stimulation pulse is applied across the electrode ⁇ ). In the alternative mode, the electrode is used as a sensor. For example, the electrical contact with the skin is measured.
- a switch assembly 40 is associated with each electrode 8.
- a corresponding switch assembly may have a plurality of associated electrodes.
- the switch assemblies 40 are formed as units separate from the controller 4 and remotely located.
- the switch assemblies preferably do not include user interfaces of the input or output.
- the switch groups may be provided with a light to signal to the user when the respective switch assembly is active.
- no input and / or output means are provided.
- the switch assemblies 40 may be constructed differently in alternative embodiments.
- the switch assemblies 40 include an electrical (electronic) switch that can be opened and closed. In the open position, the stimulation pulses generated by the controller 4 are conducted via the power transmission conductors 9 to the associated electrode 8.
- the switch assemblies 40 receive via the conductors of the signal transmission 19 the command to open or close the switch.
- An advantage of this local and preferably in the vicinity (immediate vicinity) of the electrodes arranged switching modules consists in a significantly reduced overhead of the wiring. Thus, no separate conductor to the controller 4 is needed for each switch assembly. In contrast to the embodiment shown in FIG. 8, a conductor 9 of the power transmission that originates from the controller or a power supply is sufficient.
- the switching assemblies 40 may be connected to one or more sensors 3 and the switching of the switching pulses to the electrodes 8 is done in response to the measurements provided by the sensors 3.
- they include some "switching intelligence" and / or are arranged to independently generate a stimulation pulse In this case, no immediate stimulation pulse is transmitted via the signal or control conductors 19 from the controller 4. Instead, a Depending on the measurement results of the sensors 3 and parameters of the activation, which it receives from the controller 4, the switch assemblies 40 themselves generate the power signal of the electro-stimulation.For this, the switching assemblies 40 require a power supply via the power transmission line 9.
- a common power transmission line can be provided for a plurality of switching modules.
- FIG. 9 shows a variant in which a very large number of electrodes are connected in a matrix-like manner.
- the number of conductors 9 of the power transmission which emanates from the controller 4, significantly less than the number of electrodes 8.
- the controller 4 generates on each of the conductors shown an electro-stimulation for one or more of the connected electrodes.
- a signal is transmitted via the control conductor 19, which determines which of the power switches of the switching assemblies 40 are to be switched on so as to conduct the electro-stimulation from the conductor 9 to the desired electrode 8.
- the control conductor 19, may be embodied as a bus which, for example, transmits serial data.
- the switch assemblies can be set up to generate the signal or the electrostimulation themselves.
- the switching modules can be designed differently. In one variant, they are optimized so that they have the absolute smallest size. In this case, they consist practically only of the switching device, which may be a transistor or other electronic switch. Thus, the volume of the switch assembly may be less than 0.5 cm 3. In the case of a flat design, they can be integrated into the clothing without the user perceiving too unpleasantly large "knots.” In this variant, each electrode (or each pair of electrodes) is preferably associated with a switch assembly.
- the switching intelligence can be provided for a plurality of electrodes. So may be included in the clothing several switching components. In this case, the volume can get bigger than 1 cm 3 and less than 20 cm 3, preferably smaller than 10cm. 3
- This variant of the switch assembly is thus so large that it is clearly noticeable to the user. It is integrated in the clothing in places that are perceived by the user as not disturbing. This can be, for example, in the neck, on the chest, in the area of the belt, on the wrists or ankles or, for example, on the calves. In this case, for example, at least three switch assemblies can be integrated on a piece of clothing.
- the switch assemblies preferably do not include any haptic input devices, such as switches or buttons for switching on or off or controlling, in both aforementioned variants.

- the method works on the principle of afferent collateral inhibition.
- the principle of afferent collateral inhibition is described below: muscle work (muscle contraction) is only possible if, upon activation of the agonist, a simultaneous inactivation of the antagonist and vice versa he follows.
- afferents and efferents in the spinal cord via inhibitory interneurons.
- Fig.10 the reception of the sensor data is shown, which receives the activity signals of the musculature, and to a controller, such as a mobile terminal (Smartphone, Tablet PC) sends.

- a virtual trainer 603 who prays an exercise and gives instructions.
- the practicing person repeats this exercise.
- the trainer gives a training instruction that the user should simulate. If he does not complete the exercise correctly, it will be detected by a sensor and the software processes the signal and sends a haptic signal to the user (electrotactile, vibrotactile or mechanotactile).
- This signal can be an EMS signal, which is set up directly to a musical signal. kelept réelle effect. Alternatively, a signal may be provided at a frequency that is not suitable for muscle activation. This signal is sensitively detected by the body and the user can then consciously perform a corrected movement.

- Vital signs can also be recorded as described above.
- 603 EMS signals can be transmitted by the virtual trainer. There are several technical possibilities for measuring movement (eg acceleration sensor, sports biomechanics).
- piezoelectric acceleration sensors made of silicon are used, which convert the pressure fluctuations caused by an acceleration into electrical signals.
- Small, robust sensors have only a few grams of mass and high sensitivity with good signal resolution.
- Recent piezoresistive and piezocapacitive sensors provide a signal that shows not only the acceleration, but also the inclination of the sensor (position relative to gravity). In a horizontal or vertical position, the DC (DC) components of the signal differ, and therefore the position of the body in space can also be determined.
