A group of researchers at the Korea Advanced Institute of Science and Technology (KAIST) has synthesized a nanogenerator – a flexible piezoelectric energy harvesting device based on biological templates. The biotemplated nanogenerator is low cost and it can be self-powered by simple finger movements that could be used to power small commercial LCD screens and… »

Researchers at Georgia Insittute of Technology (Georgia Tech) developed arrays piezotronic transistors capable to convert mechanical motion into electronic signals. Named “taxels”, these touch-sensitive transistors could provide significant improvements in resolution, sensitivity and functionality for tactile sensing. The arrays could aid in robotics as tactile sensors, provide better security in handwritten signatures and offer new… »

There are many power sources today as wind power, hydro-power, tidal, geothermal, solar power as well as the power used in wristwatches, where oscillations that occur while we move our hand power the watch. Researchers from the University of Michigan are developing a similar, more sensitive, technology. Their small generators could produce enough electricity from… »
