Abstract
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.
