MUSCLE MICRO-MOTION DETECTION ELEMENT, SWITCH DEVICE, HUMAN-COMPUTER INTERACTION SYSTEM, AND FRONT-END DEVICE

WIPO Patent Application WO/2018/227896

A1

A muscle micro-motion detection element, a switch device, a human-computer interaction system, and a front-end device, relating to the field of human-computer interaction. The muscle micro-motion detection element comprises a friction nanometer generator which is attached to a to-be-detected position and is used for converting mechanical energy of muscle micro-motion into electric signals. The friction nanometer generator comprises electricity generating components (101, 206, 301) and second electricity generating components (102, 202, 302) which are oppositely provided, one of which is configured to be attached to a living body that controls muscle micro-motion. The first electricity generating components (101, 206, 301) and the second electricity generating components (102, 202, 302) can be shifted relative to each other under the action of muscle micro-action to generate the electric signals. Friction layers (101, 206, 301, 102, 202, 302) with opposite electrical properties during friction are provided, and the micro displacement of the muscle micro-motion is used as a detection signal source, so that the sensitivity of the muscle micro-motion detection is improved.
