“Carry out all my demands or the entire country’s electricity will be cut off.” Is this another line from a suspense film, or is it a palpable threat made possible with a computer keyboard? “Today, there is a growing trend amongst hackers around the world to threaten national infrastructures for ransom,” says Dr. [...]
Researchers show off tiny piezoelectric energy capture sensor
Working within the Holst Centre program on Micropower Generation and Storage, researchers have developed a small piezoelectric device capable of harvesting 85 microwatts of electricity from vibrations. Fabricated using MEMS technology, the fully autonomous temperature sensor generates enough power to wirelessly measure and transmit environmental data to a base station every 15 seconds.
The piezoelectric effect [...]
Harvesting Energy From Nature’s Motions
By taking advantage of the vagaries of the natural world, Duke University engineers have developed a novel approach that they believe can more efficiently harvest electricity from the motions of everyday life.
Energy harvesting is the process of converting one form of energy, such as motion, into another form of energy, in this case electricity. Strategies [...]
