Osram has revealed a prototype laser emitter module for projection within augmented reality glasses. The lasers are 640nm red, 520nm green and 450nm blue, in a 7 x 4.6 x 1.2mm (39mm3) surface-mount package. Branded Vegalas, the “prototype design for the module demonstrates that a light engine for smart glasses can be compact enough to fit ...

The Japanese National Institute for Materials Science (NIMS) and SoftBank have developed a 500Wh/kg lithium-air battery. “Despite their very high theoretical energy densities, only a small number of lithium-air batteries with high energy densities have actually been fabricated and evaluated,” according to NIMS. “This limited success is attributed to the fact that a large proportion by ...

MikroElektronika has introduced a sensor and interface board for measuring turbidity – the cloudiness of a liquid. Turbidity Click Bundle incudes a populated PCB conforming to the company’s Click interface standard, and Amphenol TSD-10 turbidity sensor, and a 150mm wire with the appropriate connectors on the end. TO get an ide of size, the slotted ...

Italian and Iranian scientists have replaced spin-coating with a simple piece of paper in a process to make perovskite solar cells. Spin coating is much like children’s spin painting, except that close control of process parameters results in the deposition of a continuous thin even film on the substrate. If aiming to deposit a poly-crystalline ...

University of Hong Kong researchers have used artificial intelligence to perform a brain scan with a conventional rare-earth magnet rather than a large superconducting magnet, and without a screened room. The ‘ultra-low field magnet’ – according to MRI nomenclature – was designed using almost 90kg of samarium cobalt as its field source – used because ...

Infineon has introduced a dual-channel smart gate driver for high-side load switches, design to control heavy loads in a 48 V board net through an SPI interface. Called 2ED4820-EM and ruggedised against vehicle transients, it can tolerate negative voltages at Vbat down to -90V and voltages up to +105V. Bus current sensing is included, with ...

STMicroelectronics is aiming at USB Power Delivery up to 60W (20V 3A) with a digitally programmable synchronous buck converter. Called STPD01, it will accept between 6 and 26.4V, and, controlled over I2C, deliver 3 to 20V in 20mV steps to meet PD specifications – with slew rate controllable up to 30mV/μs. Current can be set from ...

Texas instruments has revealed a buffer amplifier developed especially for oscilloscope inputs from dc to GHz. BUF802 signal paths “Oscilloscope manufacturers have got a choice: develop a discrete JFET input stage and risk limited performance, or develop their own asic,” TI general manager of linear amplifiers John Caldwell told Electronics Weekly. Developing a custom asic ...
