Innovative Flexible Film Enables Blink-Tracking and Noncontact Interaction

Researchers develop a static electricity-based sensor that detects nearby objects without physical touch, with potential applications in communication and safety.

• The new sensor technology uses fluorinated ethylene propylene to create an electrostatic field for object detection.
• It can sense objects made of various materials, including glass and rubber, from 2 to 20 millimeters away.
• The sensor maintains its charge for over 3,000 cycles, enhancing its durability and reliability.
• A demonstration showed the film's ability to track blinks and communicate via Morse code when attached to eyeglasses.
• Future applications could include aiding non-verbal communication and monitoring driver drowsiness.
