Abstract

A housing cladding module for a medical device is provided for collision identification. The module includes resistor elements, which are arranged in and/or on the surface and which are designed such that the resistor elements change their electrical resistance on expansion. The resistor elements are arranged in such a way that the resistor elements are expanded in the event of a collision with an object. The collision is identified easily, and the effective collision force may be ascertained.
