Amyotrophic lateral sclerosis is a progressive degeneration of motor neurons. Patients with the disease lose their ability to speak and to use their hands as the disease progresses. We have developed a new electronic communication system that enables communication by blinking of the eyes. The system consists of a light emitting diode (LED), two silicone rubber electrodes, an electrooculogram (EOG) recorder, a microcontroller, a sound reproduction board, a pillow speaker and a low power mobile phone. The two silicone rubber electrodes record the EOG induced by blinking the eyes synchronized with LED flashing. The EOG is amplified by the EOG recorder. The microcontroller detects the blinking from the amplified EOG, and then their meanings are confirmed by voice. After that, the patients intention is transmitted to the nurse by a low power mobile phone so the care giver is kept in the loop.
肌萎缩侧索硬化症是运动神经元的进行性退化。随着疾病进展，患有这种疾病的患者会丧失说话和使用双手的能力。我们开发了一种新的电子通信系统，该系统能够通过眨眼来实现通信。该系统由一个发光二极管（LED）、两个硅橡胶电极、一个眼电图（EOG）记录器、一个微控制器、一个声音再现板、一个枕头扬声器和一部低功率手机组成。两个硅橡胶电极记录与LED闪烁同步的眨眼所诱发的眼电图。眼电图由眼电图记录器进行放大。微控制器从放大后的眼电图中检测眨眼，然后通过语音确认其含义。之后，患者的意图通过低功率手机传输给护士，以便护理人员随时了解情况。
