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.
