An electronic device which includes a resilient piece, base plate and electronic source. The upper conductor is located on the resilient piece; the base plate is connected to the resilient piece, with a space between the two. The lower conductor is located on the base plate, and there is a crevice between the lower conductor and the upper conductor. The electronic source electrically connected to the upper conductor and the lower conductor. The sensor device is located on the base plate. Utilizing this structure, the electronic device can, based on the user's needs, perform testing of the subject's physiological status or test a specific site that is pressed, be used as assist for medical equipment, exercise equipment or communications facilities.
