Abstract

The invention discloses a graphene detection element for detecting the fine deformation of an equipment housing, and the element comprises a circuit board which is provided with a hollow-out part. The two faces of the hollow-out part on the circuit board are provided with graphene conductive films in a pasting manner. The graphene conductive films are attached to an insulating elastic base layer, and the upper and lower graphene conductive films are arranged oppositely. A gluing electrode is disposed between the graphene conductive films and the circuit board. The element is pasted at a to-be-detected part of the equipment. When the housing bears a force and then deforms, the effective contact area of the upper and lower graphene conductive films changes, thereby enabling the conduction impedance of the upper and lower graphene conductive films to change. Through detecting the change of the impedance, the element calculates the size of an external force, and further solves the deformation quantity of the equipment housing.

Description

technical field [0001] The invention relates to a graphene detection element, in particular to a graphene detection element used in the detection of fine deformation of equipment shells. Background technique [0002] The subtle deformation detection of the shell is mainly used in the detection of the aircraft body, the shell detection of weapons and equipment, and the shell detection of precision instruments. The loss of the aircraft structure, such as cracks in the interface of the aircraft, deformation and damage, etc. These damages reduce the strength and stiffness of the aircraft structure and affect the aerodynamic performance of the aircraft. [0003] At present, there are mainly two methods for shell deformation detection, one is manual detection with a microscope, and the other is using special detection instruments, such as ultrasonic detection and X-ray detection. The manual detection method is relatively simple but inaccurate, and the workload is heavy. The dete...
