Could bugs with tiny backpacks be the future of search and rescue?

You've heard of canaries in coal mines. Or search and rescue dogs. But how about sending a team of beetles into a disaster zone? Marketplace's Tech Report Blog wrote about the idea today:

Researchers at the University of Michigan have figured out how to use the vibrations of beetles to harness energy that powers “tiny backpacks” that said beetles would carry to help with disaster area search and rescue. The idea would be to release the insects, equipped with microphones and other sensors, into disaster zones. Kinda creepy, but I’ll take a beetle crawling over my face any day, if it means I can get a collapsed roof off me. 

From a U of M press release on the research:

"Through energy scavenging, we could potentially power cameras, microphones and other sensors and communications equipment that an insect could carry aboard a tiny backpack," Najafi said. 

Researchers at the university hope to patent the idea, and they're looking for business partners to bring the technology to market.

An academic paper on the work is published in the Journal of Micromechanics and Microengineering.
