How to harvest energy from bugs
Researchers at the University of Michigan are examining a way is to generate power from the kinetic motion (that’s movement to me and you) and body heat of insects. A research paper in the Journal of Micromechanics and Microengineering explains how piezoelectric generators can harvest tiny amounts of electricity from Green June Beetles as they move. The research suggests the energy should be used to charge a small battery attached to the beetle, in turn used to relay information from sensors on the beetles about their environment.
The researchers suggested the insects could carry tiny backpacks, possibly containing cameras and microphones or chemo-sensors along with communications equipment to transmit the information gathered about dangerous, enclosed, or unknown environments humans would not or could not enter. The study was funded by DARPA’s Hybrid Insect Micro Electromechanical Systems programme which wants to create cyborg beetles for military use. In trials, a generator was attached to each wing of a beetle and produced more than 45 micro-watts of power. Now researchers are trying to connect the generators directly to the muscles involved in flights to increase the output per bug.
