Abstract
An electronic device includes a substrate, a Wheatstone bridge circuit, a power module, and a controller. The Wheatstone bridge circuit includes a first pressure sensing electrode disposed on the substrate. A resistance of the first pressure sensing electrode varies with pressure applied to the first pressure sensing electrode. The first pressure sensing electrode is coil-shaped. The power module is electrically connected to the Wheatstone bridge circuit. The controller is configured to control the power module to provide direct current (DC) to the Wheatstone bridge circuit within a first period of time, and to control the power module to provide alternating current (AC) to the Wheatstone bridge circuit within a second period of time.
