SENSOR MODULE USING PIEZO FILM

摘要

PURPOSE: A sensor module using a piezo film is provided to simplify the manufacturing process and to enable application to all types of press force measuring devices. CONSTITUTION: A sensor module comprises a touch unit(110) and a sensor unit(120). An external press force is applied to the touch unit. The sensor unit is formed on one side of the touch unit, and includes a piezo film and one or more electrode parts(122) formed on the piezo firm. Therefore, the sensor module can measure the press force from electric signals from the electrode parts.
