Power/Performance Bits: May 18


Efficient high-voltage power conversion Researchers from École Polytechnique Fédérale de Lausanne (EPFL) and Enkris Semiconductor are working to design new power transistors with the aim of improving power converter efficiency. "We see examples of electric power losses every day, such as when the charger of your laptop heats up," said Elison Matioli, head of EPFL's POWERlab, noting that ... » read more

Power/Performance Bits: April 27


Energy-harvesting shirt Engineers at the University of California San Diego developed a 'wearable microgrid' that harvests and stores energy from the human body to power small electronics. The microgrid consists of three main parts: sweat-powered biofuel cells, motion-powered triboelectric generators, and energy-storing supercapacitors. All parts are flexible, washable and can be screen pri... » read more
