An insect’s internal chemicals can be converted to electricity, potentially providing power for sensors, recording devices or to control the bug, a group of researchers at Case Western Reserve University report.

The finding is yet another in a growing list from universities that could bring the creation of insect cyborgs - touted as possible first responders to super spies - out of science fiction and into reality. In this case, the power supply, while small, doesn’t rely on movement, light or batteries, just normal feeding.
