Elastomeric particle having an electrically conducting surface, a pressure sensor comprising said particles, a method for producing said sensor and a sensor system comprising said sensors

Abstract

An elastomeric particle () comprises a non-conducting elastomeric body () having an electrically conducting surface (). Pressure sensor elements ('″) comprising such elastomeric particles are disclosed, as well as sensor clusters () comprising such sensor elements. There is also disclosed a pressure sensor element (), comprising a resistive element () providing a conduction path, a first electrode (------), connected to the resistive element, a second electrode (′), which in a quiescent state is spaced from said first electrode, wherein the second electrode, when the pressure sensor element is subjected to a pressure, is arranged to contact said first electrode or said resistive element. Systems comprising such sensor elements and sensor clusters are disclosed, as well as methods of their fabrication.
