A new type of passive element with variable mechanical impedance is proposed in this paper. Since the proposed elements are lighter, smaller and softer than the previous passive elements, these elements have possibility of develop wearable mechanical systems. In this paper, the principles of the variable mechanical impedance of the proposed elements are explained and the basic experimental results demonstrate the performance of the proposed elements. Moreover, a wearable mechanical system for virtual reality is developed by using the proposed elements and it is shown that the developed system can be utilized as a force display in virtual world.
