Recom has created 12V and 48V variants of its 24V 450W RACM600-L ac-dc mains power supply. Like the original, they are open-frame supplies with an aluminium U-channel chassis measuring ~100 x 200x 40mm, this time delivering up to 430W by convection cooling and using convection cooling, and 600W continuously if there is sufficient airflow. Peak power from the original was ...

An intelligent patch for cardiac monitoring is amongst research projects built on flexible and stretchable PCBs from Würth Elektronik. There are two cardiac monitors, a mini version with three electrodes for short-term monitoring, and one with six electrodes for longer periods. “A completely new approach to integration was developed in this work,” according to Wurth. “It was based on a stretchable ...

Kyocera AVX has announced a range of high-capacity supercapcitor banks with low leakage. “SCM Series supercapacitor modules are rated for operating temperatures from -40°C to +65°C and lifetimes that extend to millions of cycles,” according to the company. “They are also lead-free compatible, RoHS compliant, and compliant with the UL 810A standard for electrochemical capacitors.” Initially there are five versions: ...

At Stanford University, researchers have found a way to record the activity of a single neuron without burrowing into the brain – of a rat in this case. Developed by Anqi Zhang and colleagues, the key part is a micro-probe that can be threaded through blood vessels as small as 100μm in diameter. Initially it is housed in a micro-catheter ...

Stackpole is offering 0.01% 2ppm/°C precision surface-mount resistors in sizes from 0402 to 2512 (1 x 0.5mm to 6.3 x 3.1mm). Part of its RNCF range, these highest spec parts don’t come in the wide value range of lesser RNCF resistors. For example: 0402 types are available between 49.9Ω and 4.99kΩ, then 2512 has the widest span of options,  between ...

Graphene-like foam sensors from Stirlingshire-based Integrated Graphene can detect lactate concentrations for medical and fitness applications, according to research at the University of Bath. The company describes its patented substrate as “a three-dimensional carbon-based nano-material consisting of twisted multi-layers of atoms arranged in a  honeycomb structure”. To form a lactate-detecting electrode, boronic acid was absorbed into the foam, and then ...

The growing market for home medical devices presents new design challenges to ensure that people with no medical training, or who are elderly or disabled, can use equipment properly and safely, by Ron Stull of Bel Fuse. The sophistication of medical technologies used in non-clinical settings ranges from those giving basic assistance to complex equipment for delivering advanced treatment. However ...

Michael Clifford, Roman Trogan and Matthew Hayes say synthetic biology is a reality and explain how a bio-tech startup is working with a seasoned silicon provider to make DNA synthesis universally available. What if we could combine physics with biology and rapidly develop new and affordable, individualised medications on the surface of a silicon chip for the treatment of cancer, ...

Researchers at the Gwangju Institute of Science and Technology in Korea have developed injectable bio-electrodes with pre-settable lifetimes. “In recent times, conductible hydrogels have attracted great attention as bioelectrode materials owing to their flexibility, compatibility, and excellent interaction ability,” according to the Institute. “However, the absence of injectability and degradability in conventional conductive hydrogels limits their convenience of use and performance ...

Melexis is encouraging innovation and drawing on the rich pool of local technology graduates at its newly-opened Innovation Lab. Positioned in the Swiss canton of Neuchâtel, the Melexis Innovation Lab is the latest addition to the Belgian company’s site in Bevaix, near Geneva. The lab was opened in December 2022 and is a centre for pre-development of sensor technology products ...
