Abstract

The invention provides a sensing apparatus. The sensing apparatus comprises a first signal sending / receiving layer, a second signal sending / receiving layer and a flexible circuit board. One end of the flexible circuit board is fixed to the lower part of the first signal sending / receiving layer and the second signal sending / receiving layer. The first signal sending / receiving layer comprises a first electrode and a second electrode which are arranged oppositely, and a first spacing layer located between the first electrode and the second electrode. The first spacing layer comprises a first surface and a second surface which are arranged oppositely; and the first electrode has an extending part extending to the second surface from the first surface of the first spacing layer. The second signal sending / receiving layer comprises a third electrode, a fourth electrode and a second spacing layer sandwiched between the third electrode and the fourth electrode. The sensing apparatus realizes signal transmission with an external system through the flexible circuit board. The sensing apparatus performs signal transmission through the flexible circuit board without an external wire, so that the overall structural strength of the apparatus is improved.

Description

technical field [0001] The invention relates to a sensing device. Background technique [0002] Sensing devices have been widely used in different fields such as industry, national defense, fire protection, and electronics. According to different sensing principles, there are many types of sensing devices, such as optical sensing devices, capacitive sensing devices, matter wave sensing devices, and the like. A typical material wave sensing device is an ultrasonic sensor, which generates an ultrasonic signal through a sensing element and receives the ultrasonic signal reflected back by the object to be tested, and generates a sensing signal based on the received ultrasonic signal to sense the detected object. Analyte. Ultrasonic sensing devices use sound waves to cover the entire surface used for sensing, and the object to be measured will block these standing wave patterns, and the corresponding attenuation can be detected at this time, so that the sensing operation can be...
