如何方便有效地采集提取表面肌電信號（SEMG）已成為SEMG 應(yīng)用的關(guān)鍵技術(shù)之
一。介紹了一種無線肌電信號采集裝置，采用電池供電，帶存儲功能，具有精度高、易操作、便攜等優(yōu)點，較好地解決了現(xiàn)有SEMG 采集裝置中存在的問題。硬件上引入了FLASH 和CP2102，實現(xiàn)了存儲功能且方便與PC 通訊。軟件上系統(tǒng)運行于低功耗模式，提供了多種操作方式。應(yīng)用結(jié)果顯示所述方法有效可行，具有較高的實用價值。
關(guān)鍵詞：肌電信號；肌電信號采集；可存儲；低功耗
Abstract: How to acquire and extract surface electromyography (SEMG) expediently and
effectively had been one of the key factors to apply the SEMG. A wireless SEMG acquisition
instrument which was battery powered, storable, high accuracy, easy to operate and convenient to carry was designed, it solved several problems exist in traditional SEMG acquisition instrument well. The usage of FLASH and CP2102 make the instrument storable and convenient to communicate with PC. The system software was designed running in low power mode, and provides several operate ways. The result of application showed the feasibility of the method described in the paper.
Key Words: SEMG; SEMG acquisition; Storable; Low power
