Power/Performance Bits: Dec. 11


Internet of Ears for smart buildings Scientists at Case Western Reserve University proposed a new way for smart homes to determine building occupancy: sensors that 'listen' to vibration, sound, and changes in the existing ambient electrical field. "We are trying to make a building that is able to 'listen' to the humans inside," said Ming-Chun Huang, an assistant professor in electrical engi... » read more

Creating magnets with electricity Researchers at the SLAC National Accelerator Laboratory, Korea Advanced Institute of Science and Technology (KAIST), Korea Institute of Materials Science, Pohang University of Science and Technology, Max Planck Institute, and the University of New South Wales drew magnetic squares in a nonmagnetic material with an electrified pen and then "read" this magneti... » read more

Power/Performance Bits: Dec. 29


Wearing your batteries In spite of the progress in wearable devices, one challenge remaining is providing less obtrusive and cumbersome power sources. To tackle the problem, researchers at Case Western Reserve University developed flexible wire-shaped microsupercapacitors that can be woven into a jacket, shirt or dress. "The area of clothing is fixed, so to generate the power density need... » read more
