戴上这副眼镜，渐冻症患者眨眼就能“发电”，还能操控轮椅！

Core Viewpoint - The article discusses the development of the world's first self-powered eye-tracking system by a team led by Professor Long Yunze from Qingdao University, which enables patients with amyotrophic lateral sclerosis (ALS) to control wheelchairs through eye movements and blinks [1]. Group 1: Technology Overview - The self-powered eye-tracking system addresses the energy supply challenges faced by traditional eye-tracking devices, which often require external power sources, creating barriers for users [3]. - The system utilizes a dual-layer collaborative approach with "contact lenses + frame glasses," making it lightweight and similar in comfort to regular glasses, while generating power solely from eye movements [3][5]. Group 2: Mechanism of Operation - The technology functions as a "micro power station" on the eye, using polydimethylsiloxane (PDMS) material that acts as a "micro-friction generator" to produce electric charges through blinking and eye movement [5]. - The glasses are equipped with transparent indium tin oxide electrodes that capture and convert the generated electric charges into recognizable electrical signals, allowing for precise control of external devices [5]. Group 3: Future Development - The research team acknowledges the need to overcome various industrialization challenges to bring the technology from the lab to widespread application and is actively seeking partnerships with relevant companies to advance the commercialization process [5].
