Piezoelectric Energy Harvesting for Flapping Wing Micro Air Vehicle and Flapping Wing Sensing Based on Flexible Polyvinylidene Fluoride

The flapping wing micro air vehicle (FWMAV) has been attracting lots of interest since the 1990s and is one research hotspots in microminiaturization design. However, along with miniaturization FWMAV development, flight endurance becomes bottleneck that significantly impedes rapid development for these aircrafts because critical limit energy supply due to limited overall size weight. In this paper, recovery technology was developed new type polyvinylidene fluoride (PVDF) piezoelectric which could generate electric potential caused by deformation characteristics PVDF material. A single crank double rocker mechanism platform designed test collection effect aerodynamic lift. surface divided into 16 grid areas be measured respectively. lift, output voltage power variations different frequency successfully obtained tests. By analyzing data, if found reflect flutter condition without equipping other sensors adding extra weight aircraft. Moreover, when accelerated 12 Hz, root mean square (RMS) increase 21 ?W 6 V respectively, enough electronic devices such as LED lights.
