Abstract

An ultrasonic detection device, including a substrate, sensing elements, a first test element, a first dummy element, at least one first common signal line, sensing signal lines, and at least one test signal line, is provided. The sensing elements, the first test element, and the first dummy element are located on the substrate. The first test element is located between the sensing elements and the first dummy element. Each of the sensing elements, the first test element, and the first dummy element includes an array of capacitive microelectromechanical ultrasonic transducers. The first common signal line is electrically connected to the sensing elements and the first test element. The sensing signal lines are electrically connected to the sensing elements. The test signal line is electrically connected to the first test element.
