  • Publication number: 20150320356
    Abstract: A compression treatment device includes a pressure sensor system. The pressure sensor system includes at least one sensor cluster positioned relative to a body part, wherein each sensor cluster includes a plurality of pressure sensor elements. Further, each sensor cluster includes at least one pressure sensor element or group of pressure sensor elements connected in parallel with another pressure sensor element or group of pressure sensor elements, and at least one pressure sensor element or group of pressure sensor elements connected in series with another pressure sensor element or group of pressure sensor elements.

  • Patent number: 9027408
    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.
