Abstract

The invention provides an intelligent friction electro-optic skin, a manipulator and a robot. The intelligent friction electro-optic skin comprises elastomer, photoluminescent particles dispersed in the elastomer and a grating with a microcrack structure, wherein the grating is embedded in the elastomer and covers the photoluminescent particles. Under the action of the transverse tensile force, the microcrack width of the grating is changed so as to change the photoluminescence intensity of the intelligent friction electro-optic skin. The intelligent friction electro-optic skin, the manipulator and the robot have good sensitivity, reversibility and stability, by coupling the adjustable photoluminescence and a friction nano-generator, optical signals can be used for sensing the transverse tensile strain, and electric signals can further be used for sensing longitudinal pressure, so that multi-dimensional mechanical force sensing is achieved.

Description

technical field [0001] The present disclosure relates to the technical field of photoluminescence and triboelectric power generation, in particular, to a stretchable triboelectric smart skin, a manipulator and a robot. Background technique [0002] As an electronic device that mimics biological skin, smart skin needs to have various properties of biological skin, such as stretchability and touch sensing properties. In addition, for humans, the skin can convert external stimuli into physiological signals, which are then further translated by the brain; at the same time, the skin can be said to be one of the most sensitive and complex sensory networks. Therefore, as a medium between the robot and the external environment, the smart skin needs to have the ability to monitor a variety of external stimuli, and should have an appropriate sensing range and high sensitivity. In recent years, many research groups have developed a series of artificial smart skins based on pressure se...
