The latest cyborg insects have generally been powered by batteries. But now Aktakka and coauthors Hanseup Kim and Khalil Najafi from the University of Michigan (Kim is currently with the University of Utah), have developed an energy scavenger that generates power from the wing motion of a Green June Beetle during tethered flight. Two generators – one on each of the beetle’s wings – use piezoelectric devices to produce a total of 45 µW of power per insect. The researchers predict that this power could be increased by an order of magnitude through a direct connection between the generator and the insect’s flight muscles. Read on at PhysOrg
