Abstract: An electronic device for detecting pressure is provided. The electronic device includes a printed circuit board (PCB) including at least one element or circuit pattern for driving the electronic device, at least one electrode pattern formed to detect a pressure in the wiring layer included in the PCB, an elastic member arranged to be at least partially overlapped with the electrode pattern, and a pressure sensor circuit electrically connected to the electrode pattern included in the PCB. The pressure sensor circuit is configured to apply a voltage to the electrode pattern and measure intensity of the pressure based on a change in the voltage applied to the electrode pattern.
