The development of waterproof welfare equipment

研制了一种防水型主动肌电电极，用于福利设备。在空气或水中的测量信号的质量进行了比较。结果是，最小力水平在每种条件下都没有变化。为了今后的发展，我们制作了无线系统的原型，并开发了降低电力消耗的通信协议。为了降低控制器的价格或简化控制器，采用了一种可编程逻辑控制器。位置和阻抗由肌电活动控制。

Waterproof active EMG electrode was developed for welfare equipment. The qualities of measured signals in the air or water were compared. The result was that the minimum force level did not changed in each condition. For the future development, a prototype of wireless system was made and the communication protocol for reducing electric power consumption was also developed.The prosthetic arm was made as trial models. In order to reduce the price or simplicity of controller, a servomotor was adopted. The position and impedance was controlled by EMG activities.
