Research company Roke Manor Research in Romsey have developed a coin-sized transmitter that requires no batteries and can send a signal as far as 12 miles.

The device known as Agitate has a plethora of uses, lending themselves to things like life jacket and livestock tracking, but also, since the device is activated via a nudge – an early warning system for damaged structures.

Agitate is constructed of two plates which when jolted generate enough electrical energy to produce a nanosecond burst of signal across great distances. This signal, although short, is actually more powerful than a mobile phone’s.
