Apparatus for detecting a force effect and a method for detecting a force effect
First Claim
1. An apparatus for detecting a force effect, comprising:
- two electrical conductors that run substantially in parallel to one another and spaced longitudinally at a distance from one another;
a deformable spacer arranged between the two electrical conductors;
a first measuring device electrically connected to one end of each of the two electrical conductors;
a second measuring device electrically connected to a respective other end of the two electrical conductors such that the first and second measuring devices are electrically connected to one another by the two electrical conductors,wherein the first measuring device is configured to detect a change in a first variable caused by a change in the distance between the two electrical conductors that occurs in response to a force effect applied to the apparatus; and
wherein the second measuring device is configured to detect a change in a second variable caused by the change in the distance between the two electrical conductors that occurs in response to the force effect applied to the apparatus.

Abstract
An apparatus for detecting a force effect comprises two electrical conductors which run at a distance from one another, a deformable spacer which is arranged between the two electrical conductors, a first measuring device which is electrically connected to one end of the two electrical conductors in each case and an electrical component which is electrically connected to the respective other end of the two electrical conductors. The first measuring device is designed to detect a change in a variable which can be measured by the measuring device, which change is caused by a change in the distance between the two electrical conductors which is caused by a force effect at at least one place along the two electrical conductors, in order to detect the force effect.
