Wearable device to assist with the movement of limbs

Abstract

The invention relates to a wearable device, system and method to assist with the movement of limbs connected at a joint. The wearable device comprises: a linear motion generating unit to generate linear motion, the unit having distal end portions operatively connected to the limbs, whereby the linear motion generated by the unit causes the limbs to move and pivot about the joint; a force measuringunit to measure a change of force applied to the limbs or linear motion generating unit; and a displacement measuring unit to measure the displacement of the linear motion generating unit when linearmotion is generated; wherein a predetermined distance of linear motion having a predetermined velocity is generated by the linear motion generating unit to assist with the movement of the limbs basedon the change of force measured by the force measuring unit or the displacement measured by the displacement measuring unit. The wearable device has features of simple structure, easy manufacture andvery safety. 本发明涉及一种用于辅助与关节相连的附肢的动作的佩戴装置、系统以及方法。所述佩戴装置包括：用于产生直线运动的直线运动产生单元，所述直线运动产生单元具有与附肢可操作连接的远端部，在此所述直线运动产生单元产 生的直线运动使得附肢移动并围绕关节旋转；力测量单元，用于测量施加到附肢或直线运动产生单元上的力的变化；以及位移测量单元，用于测量当产生直线运动时所述直线运动产生单元的位移；其中，直线运动产生单元基于力测量单元测得的力的变化或位移测量单元测得的位移来生成具有预定速度的直线 运动的预定距离以辅助附肢的动作。本发明的佩戴装置，结构简单，易于制造且非常安全。
