摘要：
In this paper the results of the experimental characterization of a low threshold nonlinear bistable device in case of a low frequency input rotational motion are presented. The device has been investigated in case of a bi-directional uniform circular motion in the range of angular positions (45 degrees-135 degrees). The experimental results demonstrate the capability of the investigated device to generate powers up to 38 mu W with the optimal resistive load of 750 Omega in case of an input root mean square acceleration of 4.95 m/s(2) with a power conversion efficiency of about 4.3 %.
