A Modified Piezoelectric Effect Generates More Power
March 20, 2014 | Leave a Comment
Georgia Tech scientists working on a miniature generator based on an electrical energy generating phenomenon called the piezoelectric effect produced more power than expected – with a new idea called the triboelectric effect. That makes imagining powering your cell phone by simply walking around your office or rubbing it with the palm of your hand […]

An Engineered Virus Makes Electricity
May 15, 2012 | 2 Comments
Scientists from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have developed harmless viruses that convert mechanical energy into electricity using the piezoelectric effect, creating a new way to generate electric power. The milestone could lead to tiny devices that harvest electrical energy from the vibrations of everyday tasks, something that could […]

Piezoelectric Power Grows Ten Times
September 27, 2011 | Leave a Comment
The Oak Ridge National Laboratory (ORNL) has discovered a new material that has 10 times the piezoelectric effect of crystals and ceramics making it suitable for perhaps hundreds of everyday uses. A 10-fold increase is going to have impact. ORNL’s Volker Urban and colleagues at Technical University Aachen in Germany noticed the reverse piezoelectric effect […]
