Abstract

The invention discloses a bionic flexible pressure sensor, a pressure measuring device and a pressure measuring system. The pressure sensor comprises a bionic patch module, a sensor module and a wireless transmission module, wherein the bionic patch module comprises a patch substrate and a bionic structure group, the sensor module comprises a first polar plate, a second polar plate, a third polarplate and a dielectric layer, the second polar plate and the third polar plate are arranged in parallel in the same plane, the plane is parallel to the first polar plate, the dielectric layer is arranged between the plane and the first polar plate, the bionic structure group is arranged on a surface of the patch substrate, and data measured by the sensor is sent to external equipment through the wireless transmission module. The bionic flexible pressure sensor is advantaged in that technical problems that in the prior art, the pressure sensor and a to-be-measured object are difficult to make good contact and fix, so that measured data have large deviation, and the measured data cannot be sent to the external equipment in a wireless transmission mode are solved, and the bionic flexible pressure sensor can achieve wireless data transmission and is high in measurement precision.

Description

technical field [0001] The invention relates to the technical field of pressure sensors, in particular to a bionic flexible pressure sensor, a pressure device and a monitoring system. Background technique [0002] PEN: polyethylene naphthalate; [0003] PDMS: Polydimethylsiloxane; [0004] Ecoflex: Organic platinum silicone rubber produced by American Smooth-On Company. [0005] With the continuous development of science and technology, monitoring and detection technologies in various fields have also been widely used. As an important monitoring and detection device, pressure sensors play a vital role in the field of medical equipment. The accuracy of pressure sensor measurement and the stability during use determine the results of monitoring or detection. [0006] However, due to the structural factors of the pressure sensor, it cannot achieve good contact and fixation with the object to be measured during use, which leads to large deviations in the measured data, and ho...
