System for providing sensor and actuation functionality for touch input device

Abstract:

A touch input system comprising a touch input device and an actuation and sensing system is presented. The actuation and sensing system has a transfer structure adjacent to a first surface of the touch input device, the transfer structure having a first portion and a beam extending from an edge of the first portion. The actuation and sensing system further has a transducer patch disposed on the beam. The transfer structure is configured to transfer forces between the touch input device and the transducer patch, such that movement of the touch input device by an external force causes deformation of the beam and of the transducer patch, and such that actuation output by the transducer patch causes movement of the touch input device. The transducer patch has a layer of transducer material that is configured to act as a sensor, and is configured to act as an actuator.
