Specific electrical scalp stimulation appears to reduce depression

A specific type of weak ac current stimulation to the scalp has markedly improved depression symptoms in ~70% of participants in a preliminary clinical study, according to the University of North Carolina. The signals mimic the individual ‘alpha oscillations’ – waveforms which appear at 8-12Hz on an electroencephalogram (EEG). Electronics Weekly has no way of ...

Cathode dots make faster charging Li-ion batteries

Tiny BaTiO3 islands on the surface of LiCoO2 cathodes in Li-ion batteries can dramatically increase charge rate, according to scientists at Tokyo Tech and Okayama University, and they have worked out why “While Li-ion batteries have proven to be very useful, it is not possible to charge them quickly enough with high currents without running ...

APEC: TI’s 100V 1A dc-dc buck

At the Applied Power Electronics Conference (APEC) next week, TI will demonstrate a 6-100V buck converter capable of delivering 1A, with low waste – 10.5µA no-load input quiescent current (25 to 12V at 1mA) and 3µA shut-down quiescent current. Called LM5164, the constant-on-time synchronous step-down regulator has integrated high and low-side n-channel power mosfets (725mΩ buck switch, 340mΩ synchronous rectifier ...

1in square dc-dc delivers 12W for rolling stock, and forklifts

Recom is aiming at rail rolling stock with a 25 x 25mm (actually 1 x 1inch) dc-dc converter that can deliver 12W. Called RP12-AR, the modules operate at up to 90% efficiency and up to +88°C ambient at full load – so no derating, and neither forced cooling nor additional heatsinks are required when operating ...

IoT radar beam is set by bending its flexible PC, and more gems at Embedded World

Fraunhofer IZM has re-spun the idea of mechanically-steered radar, and developed a PCB-based IoT radar that can be bent into shape to customise its beam. Called Flex-Radar, its antennas are built into two polyimide wings (laid flat in the photo). Instead of active beam steering – which would be too expensive for intended applications, the ...
