Flapping-wing robotic insects are small

highly maneuverable flying robots inspired by biological insects and useful for a wide range of tasks

including exploration

environmental monitoring

search and rescue

and surveillance.Piezoelectric actuator has advantages of high efficiency and power density in very small geometries

which shows application prospect in microrobotic field.Experiment is realized by boost converter stepping up a3.7 V Li cell to 250 V.By establishing drive requirements of piezoelectric actuators

circuit topologies and different control mode suitable for different driving types of piezoelectric actuators in microrobotic applications

and present G level drive circuits.
