Sensing device

Abstract

A sensing device is provided, which comprises: a substrate; a circuit layer disposed on the substrate, the circuit layer comprising a switch element; a reflector disposed on the circuit layer, the reflector comprising a first reflection part and a second reflection part separated from each other, wherein the first reflection part is electrically connected to the switch element, and the second reflection part receives a voltage; and a sensing element disposed on the reflector, the sensing element separated from the reflector by a gap, wherein the sensing element comprises a first absorbing part, a second absorbing part and a sensing part disposed on the first absorbing part and the second absorbing part; wherein in a normal direction of the sensing device, the first absorbing part and the second reflection part are not overlapped, and the second absorbing part and the first reflection part are not overlapped.
