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.
La présente invention concerne une particule élastomère (1, 1, 1') qui comprend un corps élastomère non conducteur (2) ayant une surface électriquement conductrice (4a, 4b, 6). L'invention concerne également des éléments capteurs de pression (20, 20', 20' ; 30, 30', 30', 30'') comprenant de telles particules élastomères, ainsi que des grappes de capteurs (50', 50'', 50IV, 50V, 50VI, 50VII, 70) comprenant de tels éléments capteurs. L'invention concerne également un élément capteur de pression (40, 40', 40', 40'', 40IV, 40V, 40VI, 40VII), comprenant un élément résistif (44, 44', 44') offrant un trajet de conduction, une première électrode (42a, 42a-1, 42a-2, 42a-3, 42a-4, 42a-5, 42a-6), raccordée à l'élément résistif, une seconde électrode (42b, 42b'), qui, dans un état passif, est espacée de ladite première électrode. Lorsque l'élément capteur de pression est soumis à une pression, la seconde électrode est disposée pour entrer en contact avec ladite première électrode ou ledit élément résistif. L'invention concerne des systèmes comprenant de tels éléments capteurs et des grappes de capteurs, ainsi que des procédés pour leur fabrication.
