Abstract
The invention relates to a tactile pick-up for making contact with an object and emitting signals which are representative of the deformation caused by the object. The pick-up comprises a supple layer of variable electrical conductivity as a function of its state of compression, a matrix of measuring electrodes each connected to an output lead, and a large number of conducting elements connected to an electric source fixing their potential at a determined excitation value.
