(PhysOrg.com) -- By taking advantage of the way crickets communicate, researchers are building "cyborg crickets" that could form a mobile communications network for emergency situations, such as detecting chemical attacks on the battlefield, locating disaster victims, monitoring gas leaks, and acting as smoke detectors.
This kind of living, mobile communication network would include groups of not only crickets, but also cicadas and katydids. Like their natural counterparts, the cyborgs would communicate through wing beats. Containing a package of electronics and sensors, the insects would change their call tone in the presence of various chemical and biological agents on the battlefield, or even the scent of humans trapped in rubble after natural disasters.
The technology's designer, Ben Epstein, came up with the idea during a visit to China, where he heard cicadas changing calls in response to each other. Recently, the Pentagon has awarded Epstein's Point Pleasant Beach, New Jersey-based company, OpCoast, a six-month contract to develop a mobile communications network for insects. The biggest challenge will be to fit all the necessary electronics into a tiny body, and then make hundreds or thousands of them in each network.
The network could potentially extend across large distances, as some katydids can be heard up to a kilometer away. As the cyborg insects transmit the call from neighbor to neighbor, the cascade effect eventually transmits the signal to ground-based transceivers, where humans can respond.
