Abstract
A touch device comprises a base, a membrane pressure sensor arranged on the base, a touch sensing layer covering the membrane pressure sensor, and a force feedback structure arranged on the lower surface of the touch sensing layer and electrically connected to the membrane pressure sensor. The membrane pressure sensor is configured to generate a pressing signal related to the force applied to it, and the force feedback structure is configured to receive the pressing signal and generate a feedback force corresponding to it.
