A Generator for Your Shoes
October 1, 2014 | Leave a Comment
Scientists at the Center for Research in Advanced Materials (CIMAV) have developed a device that fits inside a pair of shoes that harvests the energy made available when someone walks. This energy is then stored in AAA or watch batteries. The team designed a pill-shaped cylinder adapted to a shoe in order to store the […]

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 […]

Mechanical Energy to a Battery in One Step
August 22, 2012 | 1 Comment
Zhong Lin Wang, a Regents professor in the School of Materials Science and Engineering at the Georgia Institute of Technology leads a team that has developed a self-charging power cell that directly converts mechanical energy to chemical energy, storing the power until it is released as electrical current. The technology eliminates the need to convert […]

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 […]
