Harvesting energy from the human knee

Imagine powering your devices by walking. With technology recently developed by a group of researchers at the Chinese University of Hong Kong, that possibility might not be far out of reach.

Artificial 'power plants' harness energy from wind and rain

Fake plants are moving into the 21st century. Researchers developed literal "power plants"—tiny, leaf-shaped generators that create electricity from a blowing breeze or falling raindrops—and described them in ACS Sustainable ...

Development of a self-resonant smart energy harvester

The Internet of Things (IoT) is a network based on wireless sensor nodes that provide resources and information. For the long-lasting use of IoT devices, their batteries must be replaced, or a number of power line connections ...

Harvesting vibrational energy from 'colored noise'

The energy demands of today's ubiquitous small electronic devices—including sensors, data transmitters, medical implants and 'wearable' consumer products such as Fitbits—can no longer be met by chemical batteries alone. ...

Photosynthesis copycat may improve solar cells

A relatively new kind of semiconductor, layered atop a mirror-like structure, can mimic the way that leaves move energy from the sun over relatively long distances before using it to fuel chemical reactions. The approach ...
