First self-powered device can transmit data wirelessly over long distances

Leave the batteries behind. How scientists created the first self-powered device.

Recent advancements in sensor technology and electronics have allowed electronics to generate enough energy from movements. According to a new study, scientists have developed the first self-powered nano-device that can transmit data wirelessly.

The device has a nanogenerator that generates electricity from mechanical vibrations. There's also a capacitor that can store the extra energy and a Bluetooth-like communication system that transmits data wirelessly over distances of more than 30 feet.

It's not far-fetched to think that surveillance cameras could travel in the air and be powered by the wind, wearable personal electronics could be powered by the person's strides and implantable medical sensors could be powered by the patient's blood flow. It's feasible that in the future, sources like airflow, solar or chemical energy could power devices so batteries don't have to.
