Printable Batteries for Embedded Electronics

Despite gradual advancements in recent years, conventional battery cells are big, heavy and expensive, making them unpractical for the many applications in which weight or price play an essential role. Researchers at the Fraunhofer research facility in Germany have taken a radically different approach towards the building process and have developed an incredibly light, thin and inexpensive battery.The batteries weigh less than 1g each, are less than a millimeter thick, and are also environmentally friendly in that they don't contained any mercury. They are also quite inexpensive at $0.10 each.

Multimedia Body Paint

"Bare" is a new parasitic technology being explored where you apply the special paint to your body via brush, stamp, or spray. The paint acts as a medium to send information from a person to another, transmit data from a person to a computer, or power small LEDs. The circuitry between the ink and the electronic device is completed when the small electrodes are placed directly on to the skin, which in turn transmits the :

Chewing Robot Helps Dentists

UK researchers have developed a Chewing Robot to study the wear and tear on dental elements, such as fillings, crowns and bridges. By reproducing the motion and forces sustained by teeth within a human mouth, the robot has the potential to dramatically improve the process of developing and testing new dental materials.The Chewing Robot concept is on display at the Royal Society Summer Science Exhibition, which runs until the 4th of July at the Royal Society in London.

Tiny Reconnaissance Aircraft

A tiny ‘nano air vehicle’ that hovers by flapping its wings has received a Phase II contract extension worth $2.1 million for its NAV program.The tiny craft, which carries its own power supply, has progressed towards achieving AV's goals of a creating a machine that can hover for extended periods, fly at forward speeds up to 10 meters per second, withstand 2.5 meter per second wind gusts, operate inside buildings, and have up to a kilometer command and

Wheelchair Steered by Brainwaves

Toyota and Japanese research foundation RIKEN have teamed up to create a revolutionary wheelchair steered by mind control. This remarkable development is one of the first practical uses of EEG (Electro-encephalogram) signals.Designed for people with severe disabilities, the Toyota/RIKEN wheelchair is fitted with an EEG detector in the form of a electrode array skull cap, a cheek puff detector and a display that assists with control. To turn left, right and move forward, the driver simply thinks about the movement and the wheelchair instantly and seamlessly responds. To stop the wheelchair, the driver puffs his/her cheek. A detector on the face picks up the signal and immediately stops the wheelchair.
