The invention relates to the field of deformation induction sensors, in particular to a micro deformation induction device. The micro deformation induction device comprises a surface cover plate, a micro layer, a sensor layer, an elastic protection layer and a detection circuit, wherein a base layer, the sensor layer and the elastic protection layer are laminated in sequence; the sensor layer is made of an elastic conducting material; the detection circuit is connected with the sensor layer and is used for detecting the parameter change of the sensor layer. The micro deformation induction device is adhered to the back side of a detected object to perceive the deformation quantity from one side, so that the bending deformation of the detected object can be detected. According to the micro deformation induction device, a complicated mechanical structure of relative extrusion or twist deformation does not need to be formed between the detected object and a structural member, and complicated relative stress environment is not required. The micro deformation induction device is simple in structure and easy to mount.
Description
technical field [0001] The invention relates to the field of deformation sensing sensors, in particular to a micro deformation sensing device. Background technique [0002] A distance sensor is a sensor that uses the time-of-flight method to detect the distance of an object. The "time-of-flight method" is to calculate the distance to the object by measuring the time interval by emitting a particularly short light pulse and measuring the time from the emission to the reflection of the object. [0003] It can only measure the distance and cannot detect the displacement of the object. Therefore, people have invented the displacement sensor. [0004] Displacement sensor, also known as linear sensor, is a linear device that belongs to metal induction. The function of the sensor is to convert various measured physical quantities into electricity. In the production process, the measurement of displacement is generally divided into two types: measuring physical size and mechanical...
