Power/Performance Bits: Jan. 14


Optical memory Researchers at the University of Oxford, University of Exeter, and University of Münster propose an all-optical memory cell that can store more optical data, 5 bits, in a smaller space than was previously possible on-chip. The optical memory cell uses light to encode information in the phase change material Ge2Sb2Te5. A laser causes the material to change between ordered and... » read more

Power/Performance Bits: June 14


Origami battery A new disposable battery that folds like an origami ninja star could power biosensors and other small devices for use in challenging field conditions. The researchers, from Binghamton University, previously developed a paper-based origami battery. The first design, shaped like a matchbook, stacked four modules together. The ninja star version, which measures about 2.5 inches ... » read more
