Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] see Figures 1 to 4 According to the embodiment of the present invention, the fiber optic tactile sensor (sensing unit) 10 includes a contact layer 100 with a rough surface, a supporting layer 300 and a sensing layer 200 disposed therebetween. The supporting layer 300 is stacked with the sensing layer 200 and faces the first surface of the sensing layer 200 .

[0022] The supporting layer 300 includes a supporting layer substrate 310 and at least one supporting part 320 ; the sensing layer 200 includes a sensing layer substrate 210 , a plurality of fixing components 220 , a first single-mod...

Abstract

An optical fiber tactile sensor, comprising a rough contact layer and a sensing layer laminated with the contact layer, the sensing layer comprising: a sensing layer base and a plurality of fixing parts, each adjacent two A vacant area is formed between them, and the vacant area is divided into a first vacant area and a second vacant area; the first single-mode optical fiber, the single-mode optical fiber line segment located in the first vacant area is in a curved state; the fiber grating is prepared in the first a single-mode optical fiber and placed in the second empty area; and a strain isolation component wrapped around a part of the fiber grating to prevent the part of the fiber grating from being strained. It solves the problem that the traditional tactile sensing device cannot know the properties of the object and the slippery feeling during contact, and the bending loss is large.

Description

technical field [0001] The invention belongs to sensor technology, in particular to an optical fiber tactile sensor and a sensing array. Background technique [0002] In recent years, with the rapid development of artificial intelligence, the development of intelligent robots has also been greatly improved. One of the key technologies involved is the robot's tactile perception sensor technology, which has been supported by many research institutions at home and abroad. A lot of research investment. In intelligent robot technology, the tactile sensing sensor is a key device for the robot to judge the properties, pressure, temperature, roughness, etc. of the unknown objects it touches or grabs. The multifunctional tactile sensor applied to the robot hand can imitate the perception ability of human fingers to the greatest extent, and through machine learning technology, intelligent robots can operate more behaviors of human fingers. The performance of the tactile sensor direc...
