Samsung grows good quality graphene

Large area, single crystal wafer-scale graphene can be grown, claim Korean scientists from Samsung Advanced Institute of Technology (SAIT) and Sungkyunkwan University.

Growing good quality graphene without crystal boundaries has proved difficult, and much research is still done using flakes of natural graphene as a consequence. Coupling effects with…

UK’s ‘first green data centre’

AOC Group has submitted a planning application for a 7,000m2 data centre at Queensway Business Park in Glenrothes Fife.

The facility will be the first of its kind in the UK drawing its energy from a renewable source, claims AOC, with power coming from the largest biomass plant in…

Thin sensor measures forces in artificial limbs

A novel sensors could lead to better-fitting artificial limbs for amputees, is the claim of the University of Southampton.

It has a multidisciplinary team developing thin sensors that can be integrated in the sock-like ‘liner’ worn over the stump of an amputated limb inside the artificial limb socket…

PCB-based microfluidics for low-cost medical sensing

A fresh look at PCB fabrication could lead to on-the-spot medical tests for disease.

Key to the development is the identification, by University of Southampton researchers, that a PCB manufacturing plant has everything needed to make micro-fluidic bio-chemical sensors. Disposable cartridges made like PCBs would clip…

More on: Conventional components in flexible skin sensor

Last week US researchers revealed a flexible stretchable epidermal sensor made using off-the-shelf ICs, rather than custom components.

In a nutshell, normal components (ground to 1mm think where needed) are mounted on an 0.3mm elastic substrate and connected together by serpentined-serpentine tracks. The substrate and circuit…

Conventional components in flexible skin sensor

Engineers in the US have demonstrated soft diagnostic skin patches that use of-the-shelf ICs.

The announcement follows a flexible patch with all-flexible components earlier this week.

The patches stick to the skin like a temporary tattoo and incorporate a unique fluid-filled construction with serpentined-serpentine conductive…

Solar plane takes to the skies this spring

Solar Impulse 2 is a solar-electric aircraft designed to circumnavigate the globe.

It has 17,248 thinned (135µm) monocrystalline silicon solar cells (269.5m2 total). Claimed efficiency is 23%. The encapsulated solar cells form the upper skin of the 72m span wing, which is bent over 140 carbon…

Elastic ‘plaster’ has sensors, memory, and drug delivery

In a flexible epidermal adhesive strip, Korean and US scientists have combined muscle movement sensors, memory, and drug delivery.

“The system represents a new direction in personalised health care that will eventually enable diagnostics and therapy on devices that can be worn like a child’s temporary tattoo,” said Dae…

Planar transformers for PoE

Coilcraft has released two series of surface mount planar transformers for power over Ethernet (PoE) and -48V network power.

PL160 is rated for 160Watt 200-700kHz with a nominal 48 V input, and PL300 is rated for 300W.

Dc resistance is as low as 7.2mOhms and leakage inductance can…

ARM’s all-new compiler

ARM is to replace its compiler with a completely new one built on the LLVM open-source framework. “We are not stopping ARM Compiler 5 for at least five years,” added ARM.

The result, which will not be open-source, is to be called ARM Compiler 6, and will be…
