A flexible wearable hand gesture recognition system, method and sensor

Abstract

The invention relates to a flexible wearable hand gesture recognition system, method and sensor, belonging to the field of sensing technology and robot control technology. The hand motion gesture recognition system includes a host computer for motion gesture recognition, gloves worn on the monitored object, an RFID read-write module, and a wireless chipless sensing component arranged on the glove; the wireless chipless sensing component includes a layout The flexible strain sensor in the knuckle cover part, and the RFID tag module connected in parallel with the lead wire and the flexible strain sensor; the knuckle cover part is at least used to be placed outside the knuckle between two knuckles on the finger; on the same glove , the resistance difference between any two flexible strain sensors is greater than a preset value. The structure of the sensor on the glove is effectively simplified by improving the structure of the flexible sensing component, so that wireless chipless sensing detection can be realized, transmission wiring can be reduced, and it can be widely used in technical fields such as robot control and wireless chipless detection.

Problems solved by technology

[0003] A patent document with the publication number CN109793295A discloses a smart glove. By arranging flexible conductive sheets on the surface of the glove body, any two flexible conductive sheets are not connected and form an open circuit interface with each other in the conductive circuit. When any two flexible conductive sheets are in contact, a path is formed in the conductive circuit of the two flexible conductive sheets, so as to realize the recognition of the bending posture of the finger, which not only has a complex structure, but also has more signal transmission wiring

[0004] In order to solve the above problems, RFID sensors are usually used to build detection sensors, but there are still coil modules that need to lay out multiple detection chips and wireless power transmission, resulting in a more complex structure and difficult practical applications; in addition, it is mainly used for Solutions for detection in hard surface environments
