Efficiency inside: This Fujitsu chip for processing images in digital cameras is the first in production based on a new transistor design that offers significant power savings. A new way of designing chips could solve one of the biggest problems facing wearable computers such as Google Glass and the Samsung smart watch—their batteries generally have to be recharged every day. The novel design comes from SuVolta, which has been working since 2006 to dramatically improve the energy efficiency of transistors, the fundamental component of computer chips. The company has received $62 million in venture funding. At at the industry conference Hot Chips in California last month, SuVolta showed results from an experiment in which its technology was used to make a version of an existing chip. SuVolta’s version consumed half the power of the original while running at the same speed
