Researchers from the Purdue University have created a Bass-powered medical implant that can utilize sound waves as an energy source. This new pressure sensitive microelectromechanical system has a vibrating cantilever that’s receptive to sound within the 200Hz to 500Hz frequency spectrum. By applying such smart technology into producing medical implants, you can then get some better appliances that can convert the low-frequency vibrations into energy, so as to power themselves automatically.

Researchers at the University of Michigan are currently busying with their cyborg insects that would be used in small spaces or nuclear disaster locations to assist people to collect information or do something else. These insects are all installed with sensors in their bodies, which are powered by the energy generated from their own wing motion. When fully-developed, these insects can help to investigate hazardous environments that are dangerous to humans, thus to find their application value.

Do not think the item in the lady’s hand is an ordinary handbag. In fact, it’s a portable refrigerator.  Dubbed ‘E-Bag’, the bag comes with a cooling system, which would get the refreshment cooler while you’re simply walking. [Read the rest of this entry...]

Whenever asked what road humps are designed for, we will refer to its important functions in reducing traffic accidents by requiring the drivers to slow down. But how do they work in the night? I mean, there’s only dim light on the road and the drivers couldn’t always notice the road humps from far away, and as a result these speed breakers won’t work that effective as we’ve expected.

Fortunately some designers have thought of that question earlier and they’ve teamed up with the ‘Self-powered Safe Hump’ which is equipped with LED bulbs and therefore gives off light in the dark. Moreover, all the energy needed by the system is converted from the mechanical energy generated when the car passes by. [Read the rest of this entry...]

Since the built-in self-power module could generate power by the vibration of itself, this MP3 player does not need any outer power source.

In order to make power generating more interesting, it also comes with a circle which could fit your finger for rotating. [Read the rest of this entry...]

Researchers from Harvard University have developed a new silicon wire which looks much like a typical coaxial cable, but it’s around 100,000 times smaller. Plus, it could change light into juice. Reportedly, a single trand can output up to 200-picowatts.

This LED dice could light up randomly without any extra juice. Actually, it’s based on the Faraday principle. [Read the rest of this entry...]
