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 [...]

Scientists at the Vienna University of Technology (TU Vienna) can now produce a new and considerably more efficient class of thermoelectric material. The new molecular structure of the material has a very special layout in connection an astonishing new physical effect with tiny cages within the crystal structure enclosing cerium atoms. The Austrian team reports [...]

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 [...]

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 [...]

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 [...]
