Tiny Generator Runs Off Vibrations
Warbothong writes "Researchers at Southampton University in the UK have developed a tiny generator that uses local vibrations to output microwatts of power. The device is smaller than one cubic centimeter. It shows promise as an alternative to batteries for applications where frequent battery replacement would not be feasible. The devices are currently being used in industry where 'there is the potential for embedding sensors in previously inaccessible locations,' but its creators imagine it could be used in devices such as pacemakers, where the beating of the heart would produce ample movement to power the magnetic mechanism."
A pacemaker doesn't beat a heart. It sends a signal (sets a pace) to cause a heart to beat of it's own accord. It is possible that the vibrations from that much moving flesh/blood could translate into an useful amount of energy back into the battery.
I distinctly remember being told about "psycho-kinetic" watches...
What you actually heard was the phrase "Seiko Kinetic"; their advertisements clearly showed the mechanical parts of the charging mechanism, and made no reference to "psycho" power, whatever that might be. There's more info on it on Seiko's website.
