Power/Performance Bits: May 3

Nanowire batteries University of California, Irvine researchers invented a nanowire-based battery material that can be recharged hundreds of thousands of times. Nanowires have long been sought as a battery material. However, these filaments are extremely fragile and don't hold up well to repeated discharging and recharging, or cycling. In a typical lithium-ion battery, they expand and gro... » read more

Reducing transistor switching power One of the great challenges in electronics has been to reduce power consumption during transistor switching operation. However, engineers at University of California, Santa Barbara, and Rice University demonstrated a new transistor that switches at only 0.1 volts and reduces power dissipation by over 90% compared to state-of-the-art MOSFETs. "The steepn... » read more
