Micro Aerial Vehicles(MAVs) are the smallest artificial *** of the flapping wings MAVs are powered by electric motors of various *** report in this paper the application of piezoelectric actuators as power system for a flapping wing MAV using a compliant displacement amplification *** actuator used for this application is a pre-stressed cut piece of TH-7R type Thunder actuator.A two-bar compliant mechanism with two flexures has been developed to convert the linear displacement into angular movement and *** specimens were made from carbon fiber links and nylon *** also proposed to use the product of frequency(F) and tip displacement(D), F * D as a criteria for the characterization of an amplifying *** best specimen according to this criterion is obtained for a 5mm length flexure specimen made of three layers of *** F*D value obtained for this specimen was(0.58) *** finite element analysis results for different flexural thickness and lengths were obtained and have been compared to the experimental *** effect of both the thickness and length of the flexure on a particular arrangement has been discussed.
