Tough Hall sensors aim to replace reed and micro switches

Allegro MicroSystems has announced the release of a family of micro-power Hall-effect switching ICs in battery-powered automotive and industrial applications, as well as in less demanding environments. Called APS11700 and APS11760, the three pin (power, ground, output) devices have a simple (but protected) open-drain output and can consume as little as 6µA average from an ...

UnitedSiC introduces Kelvin contact silicon carbide mosfets

UnitedSiC has expanded its UF3C FAST series of silicon carbide mosfets to include parts with Kelvin contacts. Available in 650V and 1.2kV versions, they come in a TO-247-4L package. “The Kelvin package avoids gate ringing and false triggering which would otherwise require slowing of switching speeds to manage the large common source inductance of three-leaded ...

Battery-powered AI sound recognition with multi-year life

Battery-powered consumer electronics can have artificial intelligence hearing, according to a partnership between low-power MCU firm Ambiq Micro, mems microphone maker Vesper and sound recognition specialist Audio Analytic. They are not offering wide vocabulary speech recognition, but recognition of individual sounds. “Meeting steep power consumption demands remains the largest barrier to truly enabling AI on battery-powered edge ...

Stretchy electronic tattoo technique suits prototyping

Seeking a fast route to stretchable circuits with integrated electronics for on-skin use, a team from Portrugal and the US have developed a technique that avoids clean rooms and photo lithography. Instead, the required conductive pattern is printed onto temporary tattoo paper with an ordinary desktop laser printer. Next, a silver pasted is rubbed onto ...

Better copies of paintings using AI and 3D printing

Reproduction of paintings that look good in any light can be created by combed artificial intelligence and 3D printing, according to MIT. “If you just reproduce the colour of a painting as it looks in the gallery, it might look different in your home. Our system works under any lighting condition, which shows a far ...
