Abstract: The present disclosure provides a touch device and a manufacturing method thereof. The touch device includes a substrate, a touch electrode layer, a protective layer, and a plurality of wires. The substrate includes a first region and a second region, in which the second region is adjacent to the first region. The touch electrode layer is disposed in the first region and is completely covered by the protective layer. The protective layer has a plurality of openings. The openings expose a portion of the touch electrode layer and extend from the first region to the second region. Each wire is formed in the corresponding openings and extends from the portion of the touch electrode layer to the second region, in which each opening is partially filled with one of the wires, and thereby a recess is defined in each opening.

Abstract: A security method for monitoring an optical module and a three-dimensional sensor using the same apply electromagnetic induction to the three-dimensional sensor to monitor the optical module and a light source module. Two inductive coils corresponding to each other are arranged on the light source module and the optical module. An alternative current is inputted to one of the inductive coils and another of the inductive coils generates an inductive current. The value of the inductive current is continuously detected. When the value of the inductive current varies, the abnormality of the optical module is determined to shut down the light source module, thereby completing the security mechanism of the three-dimensional sensor.
