Kado raises $1.2m to launch wall chargers

Israeli start up Kado has raised $1.2million to help it complete development of what it claims could be the thinnest wall charger.

Kado has unveiled two chargers – one for smartphones and tablets, and one for laptops – both come with the company’s power conversion technology which is said to provide high levels of power density. “Kado’s vision is to release the global market from the vicious cycle of the inverse relationship in which smartphones and tablets need ...

Arduino-based liquid level sensing hardware

SST Sensing has partnered with Sparkfun to develop a simple to implement solution for single point liquid detection using infrared technology. The solution comprises an Optomax Digital liquid level switch which is connected to an Arduino board via the TTL output and powered by a 5V source.

Metallic hydrogen for room temperature semiconductors

Nearly a century after it was theorised, Harvard scientists have succeeded in creating atomic metallic hydrogen. In addition to helping scientists answer fundamental questions about the nature of matter, the material could have a range of applications, including as a room temperature superconductor.

Electronic properties found in boron chains

A Rice University team that simulated one-dimensional forms of boron is said to have found they possess unique properties. If the metallic ribbons of boron are stretched, they morph into antiferromagnetic semiconducting chains, and when released they fold back into ribbons.

Dark lattice modes used to create laser light

A plasmonic nanolaser that operates at visible light frequencies and uses dark lattice modes has been made by researchers at Aalto University, Finland. The results are said to open new prospects for on chip coherent light sources.

Scientists create self-healing material

A transparent, self-healing, stretchable, conductive material has been developed by scientists at the University of California, Riverside and the University of Colorado, Boulder. The material can be activated electrically to power artificial muscles and could be used to improve batteries, electronic devices and robots.

‘Safe & Sound’ wearables design challenge

Sponsored by Texas Instruments (TI), element14 invites electronic engineers, designers and makers to participate in the ‘Safe & Sound’ design challenge. To win the challenge, makers need to design a safety-oriented wearable device or solution that protects a person from personal and environmental risks, monitors personal health or protects personal property from theft.

Optical fibre sensor enables real time detection

Optical fibre sensing shows promise for monitoring the condition of structures. By embedding long optical fibres into a structure, strain and temperature distributions along the fibres can be detected. Until now, however, time of distributed measurement took from several tens of seconds to several minutes.

Fluorescent dye could fuel liquid-based batteries

Scientists at the University at Buffalo have identified a fluorescent dye called BODIPY as a suitable material for stocking energy in rechargeable, liquid-based batteries that could one day power small and large scale devices, including cars and homes.
