Abstract

<p>Pneumatic artificial muscles have characteristics that are not found in motors such as lightweight and flexible. However, it is difficult to accurately sensing of state due to large deformation during operation and nonlinearity. To solve the problem, authors focus on a piezoelectric wire sensor which can sense change of shape. In this paper, we investigated the output characteristics of the piezoelectric wire sensor when changing collision speed, load and contact surface shape for sensing of artificial muscle. Results show that while the collision speed and the output are in a proportional trend, the load and the contact surface shape have less influence on the output.</p>
