The hand uses similar signal-processing algorithms to other prosthetics on the market.
该假手的信号处理算法与市场上其他义肢相似。
The big advance is that it does not require invasive surgery or electronic implants into the residual limb to communicate with the user's brain.
它最大的进步在于无需实施侵入性手术或在残肢上植入电子设备便能与使用者的大脑通信。
Sensors on the skin record electrical activity from the remaining arm muscles.
皮肤上的传感器会记录残肢上肌肉的电活动。
In an intact arm, this activity would tell those muscles how to operate the hand.
在一支健全的手臂上，这些电活动会告诉手臂肌肉要如何操纵手部。
Instead, they are interpreted by pattern-recognition software that sends appropriate commands to the pump to move the artificial hand in the same way.
而在假手上，模式识别软件会解读这些电活动，并向气泵发送适当的命令来以同样的方式移动假手。
Meanwhile, other signals travel in the opposite direction from sensors in the hand's fingertips to nerves in the arm, whence they are relayed to the brain and provide a sensation of touch.
与此同时，其他信号则以相反的方向从手部指尖的传感器传递到手臂的神经，再从那里传递到大脑并产生触觉。
