Stretchy heart monitor tattoo measures electrical and mechanical body signals

Electrocardiograph and seismocardiograph readings can be taken simultaneously by an e-tattoo, according to the University of Texas at Austin – seismocardiography (SCG) is a measure of chest vibrations associated with heartbeats. “We can get much greater insight into heart health by the synchronous collection of data from both sources,” said Austin engineer Nanshu Lu. The active ...

Compound semi transistor stores data with less energy than DRAM or flash

Researchers at the University of Lancaster have created a non-volatile memory that might eventually store data for 1% of the energy required by DRAM and 0.1% that of flash – both modelled at 20nm. “Our device has an intrinsic data storage time that is predicted to exceed the age of the Universe, yet it can ...

SMD toroidal common-mode chokes work up to 10A

Coilcraft’s surface-mount common-mode chokes include 16 sizes for power line circuits up to 10A, suppressing noise up to 100MHz with >40dB attenuation in some cases. Consumer electronics and industrial applications are foreseen. “All EMI chokes feature a low-profile, toroidal construction in a surface-mount, magnetically-shielded package with footprints as small as 13 x 13 mm,” said ...

Nokia Bell Labs and AMBER extend battery life.

Researchers at Nokia Bell Labs and AMBER, the Centre for Advanced Materials and BioEngineering Research at Trinity College Dublin, have created a  formula for battery composition that claims to make batteries last 2.5 times longer than anything currently on the market. Increasing the energy storage capability of lithium-ion batteries necessitates maximization of their areal capacity. This requires thick ...
