Abstract

A touch plate having pressing force detection, especially a touch plate that can confirm the press operation by detecting different levels of finger press force is provided. It at least consists of a touch plate, a piezoelectric ceramic plate and a voltage detection circuit. The touch plate is used to detect and obtain finger touch and move signals. The magnitude of press strength can force the piezoelectric ceramic plate to generate delta voltage variation. After judging by a processor in the voltage detection circuit, the press operation of an operator is confirmed, so as to meet the purposes of controlling cursor movement and being the input controller of function buttons.
