In today’s concrete jungle, pavement takes up a lot of space, so we might as well cram some smarts in there. Now NASA is installing a high-tech new path that lights up, emits Wi-Fi signals and generates electricity, due to greet visitors to the Kennedy Space Center.

With their ability to generate electricity from mechanical stress, piezoelectric systems made from synthetic materials are great and all, but you know what might be even better? Piezoelectric systems made from natural materials.

In the future, we might overcome anxiety about a dying phone battery by doing a few star jumps. Researchers are developing an ultra-thin device that can generate electricity from motions as subtle as sitting down, opening up possibilities of clothes that charge phones or light up like an LCD screen.

Energy harvesting devices that generate electricity from light, heat, and mechanical pressure in a single package may soon be possible. Researchers from the University of Oulu have discovered a crystal mineral material that is able to simultaneously generate electricity from all these sources.

One of the biggest hurdles that electric cars face in going mainstream is range anxiety. To help combat this, Goodyear came up with its BHO3 concept tire, which generates electricity by converting heat and motion into current as the tire rolls – and even when it's standing still.

Falls are the leading cause of death by injury amongst seniors. Now, however, a new study indicates that subtly-buzzing insoles may help seniors regain some of the lost sensation in their feet, and thus be less likely to fall down.

Researchers are laying claim to having observed piezoelectricity in an atomically thin material for the first time. The effect was demonstrated in the world's thinnest electric generator made from a two-dimensional MoS2 material.

Canadian researchers have developed a chin strap capable of generating electricity from jaw movements. The team is hopeful that the strap will be able to harvest energy from common actions like eating, chewing and talking to power medical implants and wearable devices.

Four years ago, we first heard about how Korean scientists had proposed using sound to charge mobile phones. At the time, however, they couldn't generate enough of a current to actually charge one. Now, however, scientists have succeeded in doing so.

The Ormia ochracea fly has a unique hearing mechanism that allows it to precisely determine the location of a chirping cricket. Scientists have now duplicated that mechanism, with hopes that it could find use in hearing aids.
