Could cyborg insects act as first responders?

The next time you feel like swatting a bug, consider whether it might be packing military sensors that are gathering data about its surroundings. And maybe you, too.
Researchers at the University of Michigan are working on ways to generate power from insects’ kinetic motion and body heat while bugging the bugs as well.
In a paper in the Journal of Micromechanics and Microengineering, Khalil Najafi and collaborators created piezoelectric generators that harvest small amounts of electricity from the movements of the green June beetle.
The power could be used to charge a bug-board battery for sensors that would relay information about its environment.
“Through energy scavenging, we could potentially power cameras, microphones and other sensors and communications equipment that an insect could carry aboard a tiny backpack,” the university quoted Najafi as saying. “We could then send these ‘bugged’ bugs into dangerous or enclosed environments where we would not want humans to go.”
