Submission + - Engineers Make Power From Human Respiration (gizmocrazed.com)
Mightee writes: "Well as we advance towards shrinking things to the size of nanometers, even the useless are turning into assets. Thus here, Materials Science and Engineering Professor Xudong Wang, postdoctoral Researcher Chengliang Sun and graduate student Jian Shi are busy finding ways to turn our respiration into a potential source of energy, and that too electrical.
This is made possible by the wondrous piezoelectric effect. It is the phenomena by which some crystals such as that of lead zirconate titanate (PZT), acquire a charge when compressed, twisted or distorted. This provides a transducing effect for converting mechanical energy into electrical."
