Abstract
Embodiments of the present disclosure are generally directed to apparatuses, systems, and methods that utilize electroactive devices in connection with haptic devices (e.g., haptic touch sensors or haptic feedback elements). In some examples, a haptic feedback system may include an array of electroactive devices, each electroactive device including 1) a first electrode, 2) a second electrode, and 3) an electroactive polymer element disposed between the first electrode and the second electrode. The electroactive polymer element may include a nanovoided polymer material that is mechanically deformable in response to an electric field generated by a potential difference between the first electrode and the second electrode. The system may also include control circuitry electronically coupled to the array and configured to apply a voltage to at least one of the first electrode or the second electrode. Various other apparatuses, systems, and methods are also disclosed.
