AMS has introduced what it describes as the industry’s thinnest dedicated sensor for blood oxygen saturation (SpO2) measurement, the AS7038RB.   The sensor specialist and analogue chip supplier says it has the capability to remotely monitor this vital sign in small consumer products, such as earbuds, smart watches and wristbands. This is in addition to medical devices such as patches ...

Cambridgeshire-based Paragraf has had its graphene-based Hall magnetic field sensor tested for radiation toughness by the National Physical Laboratory (NPL). “Tests conducted by NPL have shown that following exposure to a neutron dose of 241mSv/hr, which is about 30,000 times the expected typical neutron dose rate in the International Space Station, Paragraf’s sensors are not affected by this level of radiation,” ...

University of Houston have created an elastic semiconductor with 8.57cm2/Vs charge carrier mobility, and then made transistors, logic and a sensor array from it. Carrier mobility is largely retained when stretched by 50%. The semiconductor concerned is poly(3-hexylthiophene) – ‘P3HT’. This is not the first time the team has made stretchy transistors from this material, but it is the first time that ...

Maxim has announced a pair of temperature sensors, one accurate with an I2C bus, and the other with a multi-drop 1-Wire interface. MAX31889 is accurate: ±0.25°C accuracy from -20°C to +105°C ±0.65°C accuracy from -40°C to +125°C 16bit resolution 32 word temperature data FIFO high and low threshold temperature alarms 1.7V to 3.6V operation 68µA in operation 0.55µA stand-by 2 ...

TorqSense is torque sensor from Sensor Technology, based in Oxfordshire. It is wireless, needing no physical contact with the shaft being monitored. If you manufacture in the UK, please read to the bottom Instead, two two surface acoustic wave (SAW) devices are attached to the shaft and are interrogated through an RF link to stationary electronics inside the body of the ...

STMicroelectronics has introduced a two-axis digital inclinometer for use in industrial automation and structural-health monitoring. It includes a programmable machine-learning core and 16 independent programmable finite state machines intended to save power for battery operation and reduce data transfers from edge sensors to the cloud. Called IIS2ICLX, the device has selectable full-scale of ±0.5, ±1, ±2 or ±3g (g=gravity here, not ...

Chelmsford-based Teledyne e2v is highlighting the role of its CCD image sensors in successfully capturing the first light image of the JPCam camera element of the JST/T250 telescope. The system recorded the Andromeda Galaxy (M31), located 2.5 million light years away. The company has congratulated the Centro de Estudios de Física del Cosmos de Aragón (CEFCA) and the Javalambre Astrophysical ...

Sony has announced two short-wavelength infra-red (SWIR) image sensors with 5μm pixels for industrial equipment, that also image in visible light too – with digital outputs to make them compatible with equipment set-up for visible light CMOS cameras. They are based on the company’s SenSWIR technology, with photodiodes formed in an indium gallium arsenide (InGaAs) layer, Cu-Cu connected to a ...

Toshiba has introduced a pair of linear CCD image sensors for automated optical inspection and  barcode scanning. Both are monochrome and have a 5.25μm (pitch) x 50μm pixels stacked edge-on to form an array ~7.9mm long. TCD1105GFG has 125V/lux-s sensitivity and 90 dynamic range, plus built-in electronic shutter. TCD1106GFG has 600V/lux-s sensitivity and 400 dynamic range. Dynamic ranges are defined as (saturation output ...

More details have emerged about UK involvement in two ESA Copernicus missions: Teledyne will supply infrared detectors and NIR CMOS and CCD sensors to the Earth Observation missions. The two missions – CHIME and CO2M – incorporate image sensors at the heart of the planned instruments and they will use Teledyne Imaging’s technology. CHIME Specifically, Teledyne will participate in the ...
