Abstract

The invention provides a high-sensitivity wearable elastic substance deformation quantity measuring device, which comprises a deformation quantity detection module composed of at least one polar platecapacitor, each polar plate capacitor comprising a triangular positive plate and a triangular negative plate which are arranged on two sides of a flexible insulating layer, one corner of the negativeplate being positioned in the projection range of the positive plate on the flexible insulating layer; a data acquisition module, connected with the deformation quantity detection module; a data processing module, used for receiving the digital signal output by the data acquisition module; and a power supply module. According to the high-sensitivity wearable elastic substance deformation quantitymeasuring device, the positive plate and the negative plate are both triangular, the projection areas of the positive plate and the negative plate on the flexible insulating layer are remarkably changed in the stretching process of the flexible insulating layer, rapid change of capacitance is further caused, and the detection sensitivity is greatly improved.

Description

technical field [0001] The invention relates to the technical field of electronic measurement, in particular to a highly sensitive wearable elastic material deformation measurement device. Background technique [0002] As people pay more attention to their own health, especially women pay more attention to their own weight and children who go out pay more attention to their parents' cardiovascular diseases, in order to make wearable devices more accurately detect human heartbeat, breathing, waist circumference and other physical characteristics, a highly sensitive measurement method for the deformation of wearable devices is urgently needed in the market. [0003] The invention patent of notification number CN105865536 A discloses an elastic sensor capable of stretching and measuring 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 microcompu...
