An elastomeric particle (1, 1, 1″) comprises a non-conducting elastomeric body (2) having an electrically conducting surface (4a, 4b, 6). Pressure sensor elements (20, 20′, 20″; 30, 30′, 30″, 30′″) comprising such elastomeric particles are disclosed, as well as sensor clusters (50″, 50′″, 50IV, 50V, 50VI, 50VII, 70) comprising such sensor elements. There is also disclosed a pressure sensor element (40, 40′, 40″, 40′″, 40IV, 40V, 40VI, 40VII), comprising a resistive element (44, 44′, 44″) providing a conduction path, a first electrode (42a, 42a-1, 42a-2, 42a-3, 42a-4, 42a-5, 42a-6), connected to the resistive element, a second electrode (42b, 42b′), 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. |

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:
a first electrode electrically connected to a first portion of the at least one conducting particle layer, anda second electrode electrically connected to a second portion of the at least one conducting particle layer. |
