A Highly Sensitive Self-Powered Flex Sensor for Prosthetic Arm and Interpreting Gesticulation

This paper presents a highly sensitive, self-powered triboelectric flex sensor designed for advanced applications such as prosthetic arm control and interpreting gesticulation. The sensor can efficiently detect finger bending motions and monitor hand gestures without needing an external power supply, paving the way for more intuitive human-machine interfaces.

• Development of a highly sensitive, self-powered triboelectric flex sensor.
• Demonstrated application in prosthetic arm control.
• Capability to interpret gesticulation for applications like sign language translation.
• Facile fabrication process with potential for cost-effective and scalable production.

The self-powered flex sensor was fabricated based on the triboelectric effect. Its performance was evaluated by its ability to detect finger bending motions and its application in controlling a prosthetic arm and interpreting hand gestures was demonstrated.

The sensor exhibited high sensitivity in detecting finger movements. It was successfully used to control a prosthetic arm and interpret gesticulations, showing its potential for creating more advanced and intuitive human-machine interfaces and assistive devices.
