Sensor device and sensor system

A sensor system comprising a receiving device and a plurality of at least one of the following sensor devices, for in particular only external fastening to the human and/or animal body:

• a sensor device comprising a sensor element and a transmission device for the wireless transmission of sensor signals to a receiving device, wherein additionally to the transmission device, the sensor device has a connecting device for cable-bound and/or electrical connection to a neighboring sensor device, particularly of the same type, in the state when attached to the body and/or a sensor device comprising a sensor element, comprising a transmission device for the wireless transmission of sensor signals to a receiving device and comprising a position detection device, wherein the position detection device is configured for detecting the position of the sensor device relative to a neighboring sensor device or relative to a marking, and/or
• a sensor device for in particular external fastening to the human and/or animal body, in particular according to one of the preceding claims, comprising a sensor element and a transmission device for preferably wireless transmission of sensor signals to a receiving device, wherein the sensor device is configured in such a manner that alternatively or additionally to the sensor element, an active device can be connected in particular for producing a stimulus, and/or
• a sensor device for in particular external fastening to the human and/or animal body, in particular according to one of the preceding claims, comprising an electrode as sensor element for potential measurement and comprising a transmission device for preferably wireless transmission of sensor signals to a receiving device, wherein the sensor device is configured in such a manner that the reference potential can optionally be controlled or regulated for potential measurement.
