Power/Performance Bits: Sept. 29


Implantable transmitter Researchers from Purdue University developed a fully implantable, wirelessly powered 2.4GHz radio-frequency transmitter chip for wireless sensor nodes and biomedical devices. The team says the transmitter chip consumes the lowest amount of energy per digital bit published to date, consuming an active-mode power of 70 μW at 10 Mbps while radiating -33 dBm of power, r... » read more

Power/Performance Bits: Mar. 13


Wireless charging Engineers at the University of Washington developed a method to safely charge a smartphone wirelessly using a laser, potentially as quickly as a standard USB cable. Safety features of the system include a reflector-based mechanism to shut off the laser and heatsinks. The charging beam is generated by a laser emitter that the team configured to produce a focused beam in the... » read more

Power/Performance Bits: July 11


3D chip integrates computing, storage Researchers at Stanford University and MIT developed a prototype 3D chip that integrates computation and data storage, based on carbon nanotubes and resistive RAM (RRAM) cells. The researchers integrated over 1 million RRAM cells and 2 million carbon nanotube FETs, making what the team says is the most complex nanoelectronic system ever made with emergi... » read more
