Title
(EN) LOW VOLTAGE ELECTROSTATIC JAMMING DEVICE
(FR) DISPOSITIF DE BROUILLAGE ÉLECTROSTATIQUE À BASSE TENSION
Abstract
(EN)
At least some embodiments of the present disclosure an electrostatic sheet jamming device comprising a first sheet having a first conductive layer, a first dielectric layer disposed adjacent to the first conductive layer, and a second sheet comprising a second conductive layer and disposed proximate to the first dielectric layer. The first dielectric layer is disposed between the first conductive layer and the second conductive layer. The first sheet and the second sheet are non-extensible and flexible, wherein the first sheet and the second sheet are slidable relative to each other in a first state. The first sheet and the second sheet are jammed with each other in a second state when a voltage is applied between the first conductive layer and the second conductive layer. In some embodiments, the applied voltage is less than or equal to a break-down voltage of air at a distance between the first conductive layer and the second conductive layer.

Au moins certains modes de réalisation de la présente invention concernent un dispositif de brouillage de feuille électrostatique comprenant une première feuille ayant une première couche conductrice, une première couche diélectrique disposée adjacente à la première couche conductrice, et une seconde feuille comprenant une seconde couche conductrice et disposée à proximité de la première couche diélectrique. La première couche diélectrique est disposée entre la première couche conductrice et la seconde couche conductrice. La première feuille et la seconde feuille sont non extensibles et flexibles, la première feuille et la seconde feuille pouvant coulisser l'une par rapport à l'autre dans un premier état. La première feuille et la seconde feuille sont bloquées l'une avec l'autre dans un second état lorsqu'une tension est appliquée entre la première couche conductrice et la seconde couche conductrice. Selon certains modes de réalisation, la tension appliquée est inférieure ou égale à une tension de claquage de l'air à une certaine distance entre la première couche conductrice et la seconde couche conductrice.
