Scientists have developed the first long distance wireless nano-device that is able to function entirely on power generated by itself.
Researchers at the American Chemical Society, funded by DARPA and the US Department of Energy, have succeeded in producing the first devices that will allow, for example, implantable medical sensors or wearable personal electronic.
Or indeed a future generation of airborne and stationary spy cameras could soon be used without running out of juice when something interesting happens.
The newly devised transmitters are able to send a signal over the impressive distance of 30 feet, operating on energy created from the surrounding environment of the device.
In this sense the development of the devices offers a fascinating glimpse of a battery-less world, where your smartphone giving up on you before the day is out would be assigned to the dustbin of history..
One of the researchers Zhong Lin Wang states that the devices are able to run on the piezoelectric energy of just a “gentle airflow, vibration, sonic wave, chemical, and/or thermal energy”.
The device works by a nano generator producing energy from a mechanical triggering, which is then stored in a capacitor, alongside a sensor and transmitter that are similar to a Bluetooth headset.
According to the team the signal wwould then even be possible to pick up from a commercial radio.
