Stretchable batteries could offer, if not affordable (unsure on that one) but at least comfortable battery power.


Clever Battery Completes Stretchable Electronics Package

Northwestern University’s Yonggang Huang and the University of Illinois’ John A. Rogers are the first to demonstrate a stretchable lithium-ion battery — a flexible device capable of powering their innovative stretchable electronics.

No longer needing to be connected by a cord to an electrical outlet, the stretchable electronic devices now could be used anywhere, including inside the human body. The implantable electronics could monitor anything from brain waves to heart activity, succeeding where flat, rigid batteries would fail.

Huang and Rogers have demonstrated a battery that continues to work — powering a commercial light-emitting diode (LED) — even when stretched, folded, twisted and mounted on a human elbow. The battery can work for eight to nine hours before it needs recharging, which can be done wirelessly.

The new battery enables true integration of electronics and power into a small, stretchable package. Details are published by the online journal Nature Communications.

“We start with a lot of battery components side by side in a very small space, and we connect them with tightly packed, long wavy lines,” said Huang, a corresponding author of the paper. “These wires provide the flexibility. When we stretch the battery, the wavy interconnecting lines unfurl, much like yarn unspooling. And we can stretch the device a great deal and still have a working battery.”

Huang led the portion of the research focused on theory, design and modeling. He is the Joseph Cummings Professor of Civil and Environmental Engineering and Mechanical Engineering at Northwestern’s McCormick School of Engineering and Applied Science.

The power and voltage of the stretchable battery are similar to a conventional lithium-ion battery of the same size, but the flexible battery can stretch up to 300 percent of its original size and still function.

A very innovative solution to a major problem in the developing world.


This Soccer Ball Generates Energy While You Play, And You Can Buy It Now

The Soccket is designed to replace kerosene lights in the developing world by converting games to electricity. 

The Soccket, a soccer ball that generates and stores electricity during game play, was born in 2009. The ball was immediately a hit. For every 30 minutes of play, the ball can juice up an LED lamp for three hours, cutting down on toxic kerosene lamp use. Just plug an LED lamp into the light, and voila, free energy.

Uncharted Play has made some changes to the ball since it was first developed. The first iteration could be inflated and deflated, but it didn’t last long. The second ball was really heavy. The third ball wasn’t that heavy, but it was rigid and had a full-size gyroscope inside. The version available on Kickstarter (a standard Soccket and lamp goes for $99) is dense, water-resistant, made with a super light foam, and contains a fist-sized gyroscope.

“This version is significantly lighter and more efficient in terms of power generation. The only thing we couldn’t replicate in terms of a normal ball is the bounce. It was a tradeoff between wanting it to be hard or light with no bounce,” says Matthews.

In addition to the standard ball, Uncharted Play is offering tricked-out upgrades for backers if it reaches certain stretch goals in the Kickstarter campaign. One version has emergency cell phone charging capability, so users can charge their iPhones instead of a lamp. Another features a revision to the circuit board that tells players how much energy they have generated.

Power Cell: A self charging Lithium Ion Battery


Self-Charging Lithium Ion Battery – Thank You Georgia Tech - Gas 2

Georgia Tech has made a self-charging lithium ion battery. This could be a major breakthrough for the electric vehicle (EV) industry, if it can be economized and applied to the auto industry.

Researchers at Georgia Tech started with a simple, coin sized, lithium ion battery and replaced the dividers between the electrodes with a polyvinylidene difluoride film. The films piezoelectric nature makes a charging action inside that gap through just a little pressure with no outside voltage required. Basically, you push on the battery and it charges itself.

The developers tested the battery by placing it in the sole of a shoe; just walking kept the battery charged.

Think about integrating this self-charging lithium ion battery technology into an EV. This takes the idea of regenerative braking to a whole new level. There would be no need to worry about finding a charging stationHybrids and other fossil fuel vehicles would be a thing of the past. You could continually drive without having to stop to fuel up. The fuels costs for shipping would no longer exist. The list goes on.

Satellites: Micro-thrusters for micro-sats.


A penny-sized rocket thruster may soon power the smallest satellites in space.

The device, designed by Paulo Lozano, an associate professor of aeronautics and astronautics at MIT, bears little resemblance to today’s bulky satellite engines, which are laden with valves, pipes and heavy propellant tanks. Instead, Lozano’s design is a flat, compact square — much like a computer chip — covered with 500 microscopic tips that, when stimulated with voltage, emit tiny beams of ions. Together, the array of spiky tips creates a small puff of charged particles that can help propel a shoebox-sized satellite forward.

Wireless powered drones. Impressive.


Wireless power system keeps UAV airborne for 48 hours.

Lockheed Martin have demonstrated a wireless power system that uses lasers to beam energy to an unmanned aerial vehicle. The ground-to-air recharging system was demonstrated for 48 hours before being shut off - but only as all the required tests had been completed, and could likely have stayed airborne for much longer. At the conclusion of the test the battery on the ‘Stalker Unmanned Aerial System’ had more energy stored than it did at the beginning.

The laser power system was developed by LaserMotive, who won NASA’s Power Beaming Challenge in 2009, winning the US$900,000 prize.

While this test was conducted in a controlled indoor environment using a wind tunnel, the next step will be to demonstrate it outdoors to prove it is ready for commercial and military applications.

Though just for the USA, the graphic does show just how small the current contribution of renewable energy is.


Image description: This graphic describes the sources of electricity generation for the United States in 2011. Coal provided 42 percent of electricity, followed by natural gas at 25 percent, nuclear power at 19 percent and renewable sources at 13 percent.

Of renewable sources, hydroelectric power (mostly from dams) lead the way at 63 percent. Learn more about the use of renewable sources of energy in the U.S.
