While quadrant photodiodes have been dominating the non-contact position detection market for years, engineers and researchers are now looking to Position Sensing Detectors (PSDs) as an alternative. PSDs stand out from the competition when large area measurements with precise readings are required.

Imec, Ghent University, and their partners in the European FP7 project SMARTFIBER have demonstrated the world’s first miniaturised fiber-optical sensor system than can be fully embedded in a composite material. This leads the way toward smart composites that enable continued and automatic monitoring of the structural health of the composite material in -for example- tidal blades, wind turbines, airplanes (fuselage, wings) or marine structur...

ams has claimed that the TMD3782 is the industry's first integrated ambient light, colour (RGB) and proximity sensor that is optimised for operation behind dark glass to drive intelligent display adaption in mobile devices. The optical module is able to sense light in a similar manner to the human eye, enabling more sophisticated control of the display brightness and colour.

Researchers from Holst Centre and imec have demonstrated what they believe to be the first ever X-ray detector produced on a plastic substrate that is capable of medical-grade performance. The device delivers high-resolution, dynamic images at 25fps and 200ppi with high contrast using medical-level X-ray doses.

Expanding its family of low-power ICs for hand held and mobile sensing applications, ZMDI has launched the ZOPT3100, a leading-edge RGB/ambient light and proximity sensor IC. It integrates an ambient light sensor (ALS), a colour sensor (CS), and a proximity sensor (PS), as well as an integrated IR LED driver on a single chip.

The latest report from IDTechEx, "Functional Materials for Future Electronics: Metals, Inorganic & Organic Compounds, Graphene, CNT", looks at the new electronics and electrics from the point of view of suppliers of fine chemicals and associated high added value processes.

Offering an ultra-wide ±75° angle of half-intensity, Vishay has introduced two matched pairs of high-speed AEC-Q101-qualified 940nm IR emitters and silicon PIN photodiodes. The VSMB10940X01/VEMD10940FX01 feature a profile of 1mm while the VSMB11940X01/VEMD11940FX01 offer a profile of 0.6mm. The company claim that this is the industry's lowest profile for side-looking, AEC-Q101-qualified components.

Silicon Labs has announced what the company claim is the industry’s first single-chip digital ultraviolet (UV) index sensor ICs. The Si1132 and Si114x sensors are designed to track UV sun exposure, heart/pulse rate and blood oximetry and provide proximity/gesture control for smartphone and wearable computing products.

Linear unveil a new fixed frequency, current-mode step-up DC-DC converter, the LT3905. Designed to bias avalanche photodiodes in optical receivers, the LT3905 features high side APD current monitoring with over five decades of dynamic range and better than 2% relative accuracy over the 3µA to 3mA range.

Imec today announced the release of its fully integrated silicon photonics platform (iSiPP25G) for high-performance optical transceivers (25Gb/s and beyond). Imec’s portfolio includes low loss (2.5dB/cm) strip waveguides, highly efficient grating couplers (2.5dB insertion loss), high-speed (50GHz) Germanium waveguide photodiodes, 25Gb/s Mach-Zhender and Micro-ring modulators.
