Thermal Imprinted Self-Powered Triboelectric Flexible Sensor for Sign Language Translation

This paper presents a self-powered, flexible, and highly sensitive triboelectric sensor designed for sign language translation. The sensor is fabricated using a simple, cost-effective, and scalable thermal imprinting technique to create micro-structured triboelectric layers. This method, inspired by the dermis-epidermis interlocking in human skin, enhances the sensor's performance, enabling it to efficiently detect finger gestures and interpret sign language in real-time.

• Development of a self-powered, flexible triboelectric sensor for sign language translation.
• A simple and cost-effective thermal imprinting fabrication method.
• High sensitivity and stability for detecting finger bending motions.
• Demonstration of a real-time sign language translation system.

A self-powered triboelectric flex sensor was fabricated using a thermal imprinting technique to create micro-structured layers on the triboelectric materials. The sensor's performance was evaluated based on its sensitivity to finger gestures. A system for real-time sign language translation was developed and tested using the fabricated sensor.

The fabricated sensor demonstrated high sensitivity and stability, effectively detecting finger bending motions. The real-time sign language translation system successfully interpreted hand gestures, showcasing the sensor's potential for applications in human-machine interfaces and assistive technologies for the hearing-impaired.
