Abstract

The invention relates to a tactile sensor. The tactile sensor comprises a flexible substrate (4), a micro-nano optical fiber embedded in the flexible substrate (4) and a fingerprint-like structure patch attached to the surface of the flexible substrate (4), wherein the refractive index of the flexible substrate (4) is lower than that of the micro-nano optical fiber, and the hardness of the fingerprint-like structure patch is higher than that of the flexible substrate (4). According to the scheme, the shearing force can be rapidly detected.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a touch sensor and a manipulator. Background technique [0002] The sense of touch is an important sense for human beings to perceive external information such as temperature, pressure, sliding, and vibration. High-performance tactile sensors can improve the perception and work capabilities of intelligent robots, and can also promote artificial intelligence-related fields such as intelligent manufacturing, intelligent medical care, and natural human-computer interaction. development of. With the development of flexible conductive materials, flexible wearable tactile sensors based on electricity have gradually become a research focus; perception of the external environment. The basic structure of this type of sensor is to encapsulate a conductive sensing unit inside a flexible material. When the sensor is mechanically deformed, the electrical properties of the conductive sensing...
