戴上这副眼镜 渐冻症患者眨眼就能“发电”还能操控轮椅

Core Insights - 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 aims to assist patients with amyotrophic lateral sclerosis (ALS) in controlling wheelchairs through eye movements [1][2]. Group 1: Technology Overview - The new eye-tracking system addresses the energy supply challenges faced by traditional devices, which often require external power sources, making them cumbersome for users [2]. - The system utilizes a dual-layer collaborative approach with a "contact lens + frame glasses" design, allowing it to be lightweight and comfortable, while generating power solely from eye movements [2]. Group 2: Mechanism of Operation - The system functions as a "micro power station" on the eye, using polydimethylsiloxane (PDMS) material that generates electrical charges through friction when the user blinks or moves their eyes [5]. - The glasses are equipped with transparent indium tin oxide electrodes that capture and convert the generated electrical charges into recognizable signals, enabling 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 this process [5].
