Tiny generators could produce enough electricity from random, ambient vibrations to power a wristwatch, pacemaker or wireless sensor. Tiny generators developed at the University of Michigan could ...

Random vibration testing provides energy simultaneously at all frequencies. Vibration testing can help ensure that your new design will survive its intended environment. The problem is knowing how ...

Using a more complex resonator as a dynamic magnifier, the efficiency of a MEMS-based energy harvester undergoing random impulse stimulation is greatly improved. The limitations of basic piezo-based ...
