Flexible Generators Turn Movement Into Energy

An electron microscope image shows a cross-section of a laser-induced graphene and polyimide composite created at Rice University for use as a triboelectric nanogenerator. The devices are able to turn movement into energy that can then be stored for later use.

HOUSTON - Wearable devices that harvest energy from movement are not a new idea, but a material created at Rice University may make them more practical. The Rice lab of chemist James Tour has adapted laser-induced graphene (LIG) into small, metal-free devices that generate electricity. Like rubbing a balloon

Generating Electricity From the Coldness of the Universe

A drawback of solar panels is that they require sunlight to generate electricity. Some have observed that for a device on Earth facing space, the chilling outflow of energy from the device can be harvested using the same kind of optoelectronic physics we have used to harness solar energy. New work, in Applied Physics Letters, looks to provide a potential path to generating electricity like solar cells but that can power electronics at night. This is a schematic of the experimental infrared photodiode that has generated electricity directly from the coldness of space.
