    • The invention addresses the problem of providing an electrically powered artificial hand that can be constructed with a simple configuration, the operation of which is easy to master and the control of which is highly reproducible. The electrically powered artificial hand (1) is provided with: a shape-detecting sensor (2) for detecting the shape of the forearm of an upper limb amputee; a hand section (6) having a pair of arms (7a, 7b) that are capable of opening and closing movements; and a main control unit body (8) having a sensor signal-receiving circuit for receiving the sensor signal output from the shape-detecting sensor (2) according to the shape of the forearm, and a control signal-generating and -sending circuit for generating a control signal on the basis of the sensor signal and sending the control signal to the hand section (6) to control the opening and closing movements of the arms (7a, 7b). The control signal comprises a control direction for controlling the direction of the movement of arms (7a, 7b), the direction being determined on the basis of the direction of the change in shape from a previously prescribed initial shape of the forearm, and a control magnitude for controlling the distance of movement of the arms (7a, 7b), the magnitude being determined on the basis of the magnitude of the change in shape from the initial shape.
    • 本发明解决了提供一种电动人造手的问题,其可以以简单的构造构造,其操作容易掌握并且其控制是高度可重现的。 电动人造手(1)设有:用于检测上肢截肢者前臂形状的形状检测传感器(2); 具有能够打开和关闭运动的一对臂(7a,7b)的手部(6); 以及具有传感器信号接收电路的主控制单元主体(8),用于根据前臂的形状接收从形状检测传感器(2)输出的传感器信号,以及控制信号生成和发送电路 根据传感器信号生成控制信号,并将控制信号发送到手部(6),以控制臂(7a,7b)的打开和关闭运动。 控制信号包括用于控制臂(7a,7b)的移动方向的控制方向,该方向基于从前臂预先规定的初始形状的形状变化的方向确定,以及控制 用于控制臂(7a,7b)的移动距离的大小,该幅度基于形状随着初始形状变化的大小而确定。
