Abstract
An input device is communicatively coupled to a host, wherein a movement of the input device is measured relative to a reference surface, and wherein the friction between the input device and the said reference surface is dynamically reducible. The input device comprises a housing and an actuator for contacting the reference surface. The actuator comprises a first layer comprising a piezo-electric material to which a voltage is applied and a second layer, comprising a material different than the first layer, bonded to the first layer. The application of voltage to the first layer results in a layer of air being trapped between the actuator and the reference surface. The layer of air reduces the friction from a first amount of friction to a second amount of friction between the input device and the reference surface.
