Battery-packed PowerPole boosts GoPro recording time by five times

By - September 16, 2014 7 Pictures
Even with the beefed up battery of GoPro's Hero3+, there's always the possibility of the camera cutting out right as the action heats up. Living out this scenario on the powder-coated ski hills of California led the team at Polar Pro to explore ways of not just extending battery life, but doing so without interruption. The result is the PowerPole, an extendable pole-mount with around five GoPro batteries worth of juice packed inside. Read More

Temporary tattoo lactate sensor converted into sweat-powered biobattery

By - August 14, 2014 1 Picture
Last year, researchers at the University of California, San Diego (UCSD) unveiled a sensor imprinted on a temporary tattoo that, when applied to the skin, is able to continuously monitor lactate levels in a person's sweat as they exercise. Now the research team has leveraged the technology to create a biobattery powered by perspiration that could lead to small electronic devices being powered by sweat. Read More

Sand-based anode triples lithium-ion battery performance

By - July 8, 2014 3 Pictures
Conventional lithium-ion batteries rely on anodes made of graphite, but it is widely believed that the performance of this material has reached its zenith, prompting researchers to look at possible replacements. Much of the focus has been on nanoscale silicon, but it remains difficult to produce in large quantities and usually degrades quickly. Researchers at the University of California, Riverside have overcome these problems by developing a lithium-ion battery anode using sand. Read More

New water-based organic battery is cheap, rechargeable and eco-friendly

By - June 29, 2014 1 Picture
Lithium-ion batteries have made portable, rechargeable electronics commonplace. Unfortunately, they do have some glaring drawbacks, including heat issues, being made with rare, toxic elements, and the fact the technology doesn't scale up very well, which limits applications. A team of scientists at the University of Southern California (USC) is working on an alternative in the form of a water-based organic battery that is not only cheaper and more environmentally friendly, but also holds the potential for scaling up for use in wind and solar power plants as a means to store large amounts of energy.

Researchers create flexible wires that could double as batteries

By - June 4, 2014 1 Picture
We literally live in a wired world, with wires snaking hither and yon transmitting electricity and data. Many are visible, while many more are hidden in the walls of buildings, the panels of cars, and the fuselage of aircraft. Now, imagine; what if we were able to turn each and every one of these into a battery that not only transmitted electricity but stored it too? Well, two researchers from the University of Central Florida (UCF) imagined that too, and came up with a way to use nano-technology to make wires with supercapacitance that may eventually also double as batteries.

MIT finds new way to harvest energy from heat

By - May 23, 2014 2 Pictures
Researchers at MIT and Stanford have found a new way to transform waste heat into electricity, particularly in situations where the temperature gradient is small, below 100º C (180° F). The technology uses widely available materials, and could be used to recycle the large amounts of wasted heat generated in industrial processes and electric power plants. Read More
