Abstract:
1. A pressure sensor element comprising: a non-conducting elastomeric portion; and a plurality of particles having a size in the range of 0.1 to 250 μm comprising a non-conducting elastomeric body having an electrically conducting surface, said particles being arranged as at least one conducting particle layer on said non-conducting elastomeric portion, said non-conducting elastomeric body of the particles governing the mechanical properties of the particles, said electrically conducting surface of the particles governing the electrical properties of the particles, and further, when said pressure sensor element is subjected to pressure, the relative positions of the particles arranged as the at least one conducting particle layer change, thereby changing the impedance of the pressure sensor element, wherein the pressure sensor element further comprises:
