Scientists unveil self-powered wireless nano device
In the words of William Gibson, the future is already here. It may be barely Google-able in an obscure scientific publication, but it has profound implications for the future of implantable medical (and other) sensors.
That future is a nanoscale device that manages to transmit data wirelessly up to 30 feet and operate without a battery, instead harvesting energy from the environment via such sources as the pulse of a blood vessel or the gust of a breeze.
"It is entirely possible to drive these devices by scavenging energy from sources in the environment such as gentle airflow, vibration, … Read more
