Among them, sensors have become an indispensable part, such as temperature, humidity, vibration, force and torque sensors.

[0003] For the industrial Internet, sensors play an important role in end-point sensing. However, there are many types of sensors. For mechanical sensors, installing the sensor on the object to be measured is a very important technology. The sensor sensitive unit is usually connected by tightening or fitting. The connection method must efficiently transmit mechanical energy. How the mechanical energy on the object to be measured is effectively transmitted to the sensor sensitive unit depends on the material integrity and integrity of its connection interface, and is also closely related to the rigidity and elasticity of its connection interface.

[0004] There are four common ways to connect sensor sensitive units, namely screw fastening, rivet fixing, welding and adhesive bonding. Different connection methods will cause changes in sensor detection values, such as accuracy, sensitivity, hysteresis, linearity and repeatability. Welding is the method with the least loss in mechanical energy transmission, but it is quite inconvenient in actual product use. It requires surface treatment and coating on the object to be tested. Adhesive bonding requires cleaning the surface of the object to be tested, applying a uniform thickness of adhesive, and then curing, which is quite time-consuming and labor-intensive.
