Energy scavengers developed at the University of Michigan can produce electricity from random vibrations. “The energy-harvesting devices are efficient at providing electrical power from arbitrary, non ...
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 ...
Last month’s column discussed the basics of simulating resonant or natural vibration frequencies as an introduction to performing advanced vibration analysis. Here, we delve deeper into random ...
Editor's Note: This story was originally printed in the January 2008 issue of Scientific American. We're reposting it because of new research out today by author Zhong Lin Wang. The watchmaker in the ...
Vibration testing helps to predict how well a product will withstand its intended service or transportation environment. Some new vibration controllers have the capability to replicate data recorded ...
The watchmaker in the 1920s who devised the self-winding wristwatch was on to a great idea: mechanically harvesting energy from the wearer’s moving arm and putting it to work rewinding the watch ...
