Abstract
A sensing device is provided for acquiring a surface image of an object. The sensing device includes a protective layer, a conductive material layer under the protective layer, a first conductive film layer under the conductive material layer, a sensing layer under the first conductive film layer and a substrate under the sensing layer. When a surface of the object is pressed on the protective layer, a sensing signal is transmitted from the sensing layer to the surface of the object and a reflecting signal reflected from the surface of the object is received by the sensing layer. Then, a current signal corresponding to the reflecting signal is transmitted from the substrate to a central processing unit through the first conductive film layer. Consequently, the current signal is converted into the surface image of the object by the central processing unit.
