US Army and Marine Corps PowerWalk into wearable battery trials

Development of piezoelectric and triboelectric generators that harvest the kinetic energy generated by movement has been gaining momentum over the past few years, and now the US Army and Marine Corps are taking the technology into the field. Vancouver-based Bionic Power will soon supply troops with its PowerWalk Kinetic Energy Harvester, a lightweight device worn around the knee that recharges batteries while soldiers walk.

Sin City going green: Las Vegas to use solar and pedestrian power for street lights

Cities consume a considerable amount of energy per year on lighting. And if that city happens to be Las Vegas, you can expect the bill to be a doozy. But a recently announced partnership with a New York City-based start-up is set to bolster Las Vegas' commitment to renewable energy sources. Soon enough, some of "Sin City's" sidewalks will be illuminated by EnGoPLANET's innovative, sun- and people-powered street lights.Read More

Kinetic energy-harvesting shoes a step towards charging mobile devices on the go

Through energy harvesting tiles, backpacks and insoles, there has been much talk about harnessing our kinetic energy to power mobile devices and other electronics. A team of researchers is claiming to have made a big breakthrough in the collective effort to turn human motion into usable energy, developing a new method of producing useful amounts of electricity from our footsteps.Read More

CareJack vest takes soft (and smart) approach to lifting heavy loads

Being a nurse, construction worker, or grocery stocker is a taxing and potentially risky job. Claiming almost 10 percent of lost days of work in Germany are due to lower back problems, Fraunhofer researchers in conjunction with industry partners are developing CareJack, an orthopedic prosthetic embedded with flexible, smart electronics to ensure those lifting heavy loads don't have to go home early.Read More

Graphene could find use in lightweight ballistic body armor

While graphene is already known for being the world's strongest material, most studies have focused on its tensile strength – that's the maximum stress that it can withstand while being pulled or stretched, before failing. According to studies conducted at Houston's Rice University, however, its ability to absorb sudden impacts hadn't previously been thoroughly explored. As it turns out, the material is 10 times better than steel at dissipating kinetic energy. That could make it an excellent choice for lightweight ballistic body armor. Read More

Footballers' pounding feet power community soccer pitch lights

Just over three years ago, a UK company looking to harvest the kinetic energy of pedestrians received its very installation order. Since then we've seen Pavegen's tiles turn to the crowd for school installs and being laid at the Paris Marathon. Now the firm has partnered with Shell for its biggest undertaking so far – to give a run-down community soccer field in a Rio de Janeiro favela an off-grid power supply which benefits the whole community.Read More
