Capacitive switch structure for nondiscrete, tactile and nontactile switches with customizable minimum activation thresholds

Abstract

Disclosed embodiments include a strain sensor having a flexible sensor layer, the flexible sensor layer including a dielectric layer, a first electrode layer, and a second electrode layer, the first and second electrode layers disposed on opposite sides of the dielectric layer, and a first deformable layer located on either the first or second electrode layers and wherein a deformation of the first deformation layer greater than a predetermined amount is sufficient to deform the flexible sensor layer and generate an impulse signal indicating deformation above a predetermined threshold. Embodiments may include incorporating the strain sensor into a capacitive button or switch.
