Abstract
A tactile feedback module not subject to a failure in function because of high-voltage arcing includes a circuit board and a piezoelectric unit. The circuit board includes spaced first connecting pad and second connecting pad. The piezoelectric unit includes a piezoelectric layer, a first electrode, and a second electrode. The piezoelectric layer is adjacent to the circuit board, and the first electrode and the second electrode are insulated from each other. A first voltage is applied to the first electrode and a second voltage different from the first voltage is applied to the second electrode, the piezoelectric layer generates a tactile feedback based on a voltage difference between the voltages. The disclosure also provides a method for making the tactile feedback module and a touch device.
