XP Power has launched a host of GaN-based plug-in ac-dc power supplies rated between 65W and 140W. The basic types are: PGW65 wall-mount 65W (0.37W/cm3 – 6.06W/in3) PGW100 wall-mount 100W (0.53W/cm3 – 8.72W/in3) PGD100 corded 100W (0.48W/cm3 – 7.93W/in3) PGD140 corded 140W (0.55W/cm3 – 9.0W/in3) They “are designed to conform to the Power Delivery protocol and are ideal for industrial ...

Sufficient vision for reading has been restored to volunteers with ‘dry age-related macular degeneration’ in a trial of an electronic eye implant. The implant, which works with custom AR glasses and needs no direct electrical connection, is from Californian company Science. It measures 2 x 2mm and 30μm thick, contains 378 closely-packed hexagonal pixels each 100μm across, and is inserted ...

Drones are to be evaluated in the UK for delivering defibrillators to people experiencing out-of-hospital cardiac arrest (OHCA). The University of Surrey is running the study, with Air Ambulance Charity Kent Surrey Sussex (‘KSS’), and South East Coast Ambulance Service NHS Foundation Trust. “With survival rates for OHCA in the UK currently below 10%, a key challenge is the delay ...

Seeking to improve sweat sensors, researchers at Waseda University in Japan have taken inspiration from rose petals. Sweat sensors exist and are used to monitor electrolyte levels during exercise as a way to improve hydration. The challenge at Waseda was to make a sweat sensor that could be put on and taken off when required – so no adhesive involved ...

Rutronik is stocking precision thin-film surface-mount resistors from Vishay, for industrial, medical and automotive use – all are AEC-Q200 qualified, sulphur tested and RoHS compliant. TNPW e3 resistors are an “economical alternative in the thin-film range”, said the component distributor, “ideally suited for industrial and automotive use”. Size options are 0201, 0402, 0603, 0805, 1206 and 1210, tolerance can be ...

For those looking to connect a lot of high-voltage circuits, Molex has introduced a connector with 62 2.2kVdc contacts, along with 68 500Vdc ‘low-voltage’ contacts. All pins are rated to carry 1A and contact resistance is under 8mΩ. To reach full operating potential, the terminations of the cable-mount plug and PCB-mount receptacle must be potted with epoxy. The ~40mm diameter ...

Researchers from the University of Texas at Austin have created a stick-on, thin, flexible, stretchy electrode array that can pick up EEG signals from the brain, which are around 10-times smaller than ECG signals from the heart. On to this is mounted an electronics package that extracts and wirelessly transmits the acquired signals. “Unlike EEG caps that are bulky with ...

Redwire is expanding its in-space drug development programme as it launches a new version of its PIL-BOX technology for a cancer-detection experiment. To complement the existing PIL-BOX platform, the Florida-based space infrastructure company is launching a high-volume Industrial Crystallizer. It says it will be capable of processing samples of 200 times the volume of current levels. It says the crystallizer ...

University of Bath electrical engineer Despina Moschou has been elected as a fellow of EAMBES, the European Alliance of Medical and Biological Engineering and Science. Lab-on-chip specialist Moschou developed ‘LoCKAmp’, a high-speed covid-19 test at Bath. “As well as the LoCKAmp, which within 3 minutes completes gold-standard genetic-based testing techniques previously only possible in a lab, Dr Moschou has filed ...

Cinon has created a range of 550W ac-dc single output power supplies measuring ~130 x 84 x 25.4mm. The power supplies do not have an internal fan, and 550W is only achievable with both baseplate and blown air cooling above 21.9cfm, with derating starting at 50°C ambient, and the maximum allowable load dropping to 350W at 80°C. With un-blown ambient ...
