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 […]

University of Michigan electrical engineers have built a piezoelectric generator that can harness energy from vibrations and convert it to electricity with five to 10 times greater efficiency and power than other devices in its class. It’s smaller than a penny. The UM team has built a complete system that integrates a high-quality energy-harvesting piezoelectric […]
