AI Technical Summary

Technical Problem

Flexible sensors are prone to stretching and deformation when attached to complex curved surfaces, which leads to a decrease in sensitivity and stability.

Method used

A reinforcing layer is formed on the surface of the flexible sensor to make the reinforcing unit correspond to the position of the sensor unit, thereby increasing the rigidity of the sensor unit and preventing it from being stretched and deformed during the attachment process.

Benefits of technology

It ensures the sensitivity and stability of the flexible sensor when attached to complex curved surfaces, and simplifies the usage process. The sensor shape matches the surface contour of the object being adapted, eliminating the need for reshaping.

Abstract

The embodiment of the application discloses a flexible sensor and a preparation method thereof, and belongs to the technical field of sensors. The flexible sensor comprises a flexible substrate layer, a sensor layer and a reinforcing layer. The sensor layer is formed on a first surface of the flexible substrate layer, and the sensor layer is composed of sensor units. The reinforcing layer is composed of reinforcing units, and the reinforcing units correspond to the positions of the sensor units. The reinforcing units are used for increasing the rigidity of the sensor units. The shape of the flexible sensor matches the surface profile of an object to which the flexible sensor is adapted. In the scheme provided by the embodiment of the application, the rigidity of the sensor units is increased by arranging the reinforcing units, so that the sensor units are prevented from being stretched when the flexible sensor is attached to the surface of the object, and the performance of the flexible sensor after attachment is ensured.
