Abstract

The invention provides a high-sensitivity wearable elastic material deformation measurement device, including: a deformation detection module, which is composed of at least one polar plate capacitor, and each of the polar plate capacitors includes a A triangular positive plate and a triangular negative plate, one corner of the negative plate is located within the projection range of the positive plate on the flexible insulating layer; a data acquisition module is connected to the deformation variable detection module; a data processing module , for receiving the digital signal output by the data acquisition module; and a power supply module. In the present invention, a high-sensitivity wearable elastic material deformation measurement device, the positive plate and the negative plate are both triangular, and the positive plate and the negative plate are on the flexible insulating layer during the stretching process of the flexible insulating layer. The projected area changes significantly, which in turn causes a rapid change in capacitance, which greatly improves the detection sensitivity.

Description

technical field [0001] The invention relates to the technical field of electronic measurement, in particular to a high-sensitivity wearable elastic material deformation amount measurement device. Background technique [0002] As people pay more attention to their own health, especially women's attention to their own weight and children away from home to their parents' cardiovascular disease, in order to make wearable devices more accurate detection of human heartbeat, breathing, waist circumference and other physical There is an urgent need in the market for a method for measuring the deformation amount of a wearable device with high sensitivity. [0003] The invention patent with the publication number CN105865536 A discloses an elastic sensor that can be stretched to measure deformation and stress, including a data acquisition module and an elastic sensitive element. The data acquisition module includes a multi-channel data acquisition line, a single-chip microcomputer, a ...
