Title
(EN) FORCE SENSOR AND METHOD OF MANUFACTURE
(FR) CAPTEUR DE FORCE ET PROCÉDÉ DE FABRICATION
Abstract
(EN)
A force sensor including a force sensing element is illustrated and described. The force sensing element includes one or more first electrically conductive elements arranged to be in electrical communication with a first region of the force sensing element, one or more second electrically conductive elements arranged to be in electrical communication with a second region of the force sensing element, and one or more third electrically conductive elements arranged to be in electrical communication with a third region of the force sensing element. At least a part of the force sensing element is configured or configurable to have anisotropic electrical conductivity.
