Vishay has added five solenoid-based haptic actuators to its IHPT range, which come with operation licenses from Immersion Corporation. There are four sizes, from 29 x 21mm to 44 x 37mm, that can provide forces up to 120N. Not immediately obvious from the photo, each transducer us in two parts: the top left part is a separate laminated metal bar ...

Stretchy gel sensor measures biomarkers on dry skin
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 ...
15W ac-dc PSUs are industrial and medical specified
Recom has created a 15W ac-dc power supply range that meet a wide range of international specifications including those for medical use. RACM15E-K supplies come in 80 x 23.8 x 22mm open-frame form with Molex connectors (photo below), or in a 83 x 26.4 x 29.5mm IP20 enclosure with push-in terminals and a DIN rail clip (right) – they are ...
Efabless marks chip manufacturing milestone
At DAC 2024, Efabless celebrated a milestone of 40 commercial companies designed chips using its chipIgnite and Google-sponsored OpenMPW programme. Of these, some are ready for production volumes, the majority are at the prototype/proof of concept stage, said CEO, Michael Wishart. The platform allows start-ups and smaller companies to prototype designs and innovate without having to buy a license, he ...
Washable stretchable electronics for medical wearables
4mm diameter elastomer fibres are a promising substrate for electronics in clothing, according to Nottingham Trent University, which is investigating washable stretchable medical wearables. To make the electronic fibre, a long thin flexible PCB is helically wound along, and bonded to, the elastomer core, with its components facing inwards. “The basic idea has been around for centuries – it’s the ...
140W ac-dc PSU handles 210W surges for 10s
Recom has announced a series of 140W single-output ac-dc mains power supplies that can handle 210W for ten seconds. The RACM140E-K series offers a choice of 12, 15, 24, 36 (136.8W rated) or 48Vdc depending on model. The input range is 80-264Vac and they measure 147 x 81.5mm – either 38mm tall for the open frame versions or 40mm enclosed ...
MEMS ultrasonic transducers key to detecting deep vein thrombosis
German research incubator Fraunhofer IPMS is working on a portable cuff that can be used to detect deep vein thrombosis (DVT) using ultrasound scanning from CMUTs – capacitive micromachined ultrasonic transducers. “They are considered to be the next generation of medical ultrasound sensors,” according to Fraunhofer. “The low-cost mass production of CMUTs makes them widely available. Their advantages, such as ...
Sensing lactic acid with a graphene-like foam capacitor
University of Bath researchers have created a lactic acid sensor using double-layer capacitance created when a particular sensitive molecule is attached to a graphene-like porous electrode structure and immersed in a buffer solution. Creating an ac-based capacitive sensor, as opposed to dc voltage or current based sensor, sides-steps concentration and chemical consumption issues encountered in battery-like reactions. The carbon material, ...
Nvidia packages inference to deliver generative AI for healthcare
Optimised packages of AI models and workflows with API have been packaged as NIMs (Nvidia Inference Microservices) which developers can use as building blocks to develop generative AI for healthcare, from drug discovery, med-tech and digital health products. Nvidia announced 25 NIMs at its developer conference, GTC 2024, offering advanced imaging, natural language and speech recognition, digital biology generation, prediction ...
Nvidia Blackwell GPU shares Hopper architecture but ramps up performance
As accelerated computing reaches its tipping point, Nvidia’s CEO explained the company’s plan is not to drive down costs but to scale up performance. He was speaking at Nvidia GTC in San Jose, introducing the Blackwell AI superchip. It will democratise trillion parameter AI, promises Huang, to meet the 1.8 trillion parameters computing performance of accelerated computing. In the home ...
