青岛大学最新研究登上Cell头条：自供电眼动追踪系统，利用眨眼的能量帮助瘫痪者操控轮椅

Core Viewpoint - The research presents a self-powered eye-tracking system, ET-TENG, which utilizes the energy harvested from the friction between the eyelid and eyeball during blinking, aiming to revolutionize assistive technologies for individuals with severe mobility impairments [5][13]. Group 1: Technology Overview - The ET-TENG system is based on the principle of triboelectric nanogenerators (TENG), capturing energy from blinking to power eye movement detection, potentially transforming assistive technology for conditions like ALS [5][9]. - This system overcomes limitations of traditional eye-tracking technologies that rely on external power sources and cannot function in low-light conditions, offering high sensitivity, simple structure, and strong anti-interference capabilities [6][13]. Group 2: Technical Specifications - The ET-TENG can detect a minimum eye deviation angle of 2° with an accuracy of 99%, and maintains a generated electric potential of -0.62 kV after 600 seconds of operation [10][12]. - The materials used in ET-TENG are biocompatible and highly transparent, ensuring comfort and usability similar to regular eyeglasses, while also incorporating filtering circuits to mitigate noise interference [10][12]. Group 3: Applications and Implications - The primary goal of the research is to assist individuals with mobility challenges, but the technology has broader applications, including in space exploration, automotive monitoring of driver fatigue, and enhancing virtual reality devices by reducing weight and energy consumption [12][13].
