Health-related chemicals can be detected on dry skin, according to the National University of Singapore (NUS), which developed a stretchable ‘ionic-electronic bilayer hydrogel’ sensor with the Singapore Agency for Science, Technology and Research (A*Star). The chemicals are known as solid-state epidermal biomarkers. “These biomarkers, which include cholesterol and lactate, are found in the stratum corneum, the outermost layer of the ...

HBK has launches what it describes as a “tactical-grade” embedded inertial navigation system in a 38 x 24 x 8.6mm 8.3g package – 18% thinner and 20% lighter than its earlier 3DMCV5. 3DM-CV7-INS, as it will be known, has 1.5°/hr gyro bias instability – which is where the tactical grade comment comes from, and is calibrated over its operating range ...

At the Small Satellite Conference in Utah, Imec announced a hyperspectral sensor with an on-chip line-based filter covering 450 – 900nm in 96 bands. It had equidistantly divided spectral bands and, compared with its previous generation, double the TDI (time-delayed-integration) capacity – to 10 line per band. Underneath the filter is a ‘2/3inch’ 2,048pixel image sensor from AMS – the ...

ROHM has developed an ultra-compact 1.8V – 5V, rail-to-rail CMOS op amp – the TLR377GYZ, optimised for amplifying signals from sensors such as temperature, pressure, flow rate, used in smartphones, small IoT devices, and similar applications. The size of smartphones and IoT devices continues to decrease – requiring smaller components. To accurately amplify small signals as needed in high precision ...

Panasonic has produced a range of micron-accurate industrial distance measuring sensors. Unlike its earlier similar sensors, digital output devices in the new HL-G2 series include interfaces for both Ethernet and RS-485 in each unit, selected by the cable used to connect them to the host system. They can communicate using EtherNet/IP, SLMP (seem-less message protocol), Modbus TCP or Modbus RTU. ...

The AH3712 is a latching Hall-effect magnetic sensor, protected for automotive electrical conditions, in a choice of SC59, SOT23 or SIP-3 packaging. The single output is switched ‘on’ with a magnetic pole above a certain flux density, and then switched ‘off’ when exposed to the opposite pole of the same flux density magnitude. There are three parts: AH3712: south pole ...

Nature provides the model for integrating sensors for a distributed edge AI system, say Bartosz Boryna and Zuzana Jirankova. The horseshoe crab (limulus polyphemus) is recognised by scientists as an interesting model for vision research because the animal’s body is large enough to study and its retina neurons are quite easily accessible. The crab has several compound eyes distributed over ...

Snap-off development boards are not a new idea, but they are new at Mikroe, where the idea has been combined with the company’s Click format to form Click Snap. “Users can develop their systems in the usual way using peripheral and development boards equipped with the mikroBUS socket,” said the company. “When the concept has been proven and code developed, ...

Senseeker has introduced a 1,280 x 1,024 version of its 10µm digital read-out IC (‘droic’) for short-wave infra-red imaging arrays, including quantum dot-based detector types. RD0131 as it will be known has a capacitive transimpedance amplifier (CTIA) front-end. There are three selectable gains, with well capacity of: 22k electrons (high-gain), 160ke- (medium) or 1.1Me- (low). In high gain, room temperature ...

STMicroelectronics has created a time-of-flight distance sensor for industrial use. VL53L4ED works over -40 to +105°C and in high ambient light, and provides “provides distance measurement to objects up to 1,150mm away over the full temperature range,” according to the company. “Special settings allow accurate distance measurement up to 800mm under strong ambient light [5klux].” On-board the 4.4 x 2.4 ...
