Structural Sensing and Actuation Utilizing Macro Fiber Composite

Macro fiber composite (MFC) is a new type of piezoelectric material with softness and big displacement, developed by NASA recently. It can be used for actuating, sensing and power generating. The purpose of our work is to develop new and intelligent mechatronic devices utilizing MFC. In this paper, the basic characteristic of MFC for sensing and actuating is investigated. Sensing ability of MFC is investigated. In addition, as application of MFC, active damping of the cantilever beam with MFC and the cushion made of the leaf spring with MFC are experimented. The application possibility of MFC as the structural sensor and actuator is confirmed.
