The possibilities include electronic devices produced so cheaply they could almost be one-time “throw away” products, better large-area electronics such as flat panel screens, or flexible electronics that could be folded up for ease of transport.
(December 29, 2004) Gaithersburg, Md.—A low-power, magnetic sensor about the size of a grain of rice that can detect magnetic field changes as small as 50 picoteslas — a million times weaker than the Earth’s magnetic field — has been demonstrated by researchers at the National Institute of Standards and Technology (NIST).
