Abstract

The invention discloses a surface strain sensor, comprising: a light reflecting film (11) for deforming according to a pressure change of a surface to be tested; a transparent connecting layer (12) disposed on the light reflecting film (11);a first fiber array (13) and the second fiber array (14), each including a plurality of fibers (131, 141), wherein the first ends of the plurality of optical fibers (131, 141) are connected to a transparent connecting layer (12), and the plurality of connecting positions of the plurality of optical fibers (131, 141) and the transparent connecting layer (12)are in a matrix distribution on the transparent connecting layer (12); a light emitter array (15) including a plurality of light emitters (151) which are connected in one-to-one correspondence with the second ends of the plurality of fibers (131) in the first fiber array (13); an optical receiver array (16) including a plurality of optical receivers (161), which are connected in one-to-one correspondence with the second ends of the plurality of optical fibers (141) in the second optical fiber array (141). The surface strain sensor can improve the accuracy of surface strain detection and avoidexternal interference.

Description

technical field [0001] The invention relates to the technical field of surface sensing, in particular to a surface strain detection and device and a surface strain sensor thereof. Background technique [0002] The surface strain sensor is a sensor used to detect static or dynamic data such as deformation pressure of the surface to be measured, and it is widely used in medical and industrial robots. For example, the use of surface strain sensors to detect the pulse of the human body. [0003] Taking pulse detection as an example, pulse diagnosis is one of the four diagnostic methods of traditional Chinese medicine, and occupies a very important position in the four diagnostic methods of traditional Chinese medicine. The usual method of pulse diagnosis in traditional Chinese medicine is that the doctor of traditional Chinese medicine touches and presses the radial artery of the patient's mouth with his finger, and feels the change of the patient's pulse wave by applying diffe...
