Charge multiple devices at classic charger speed

Charge multiple devices at classic charger speed
energysquare is a new generation of wireless chargers that will allow you to charge multiple devices at the same speed as classic chargers, just by putting it on a wide and ultra-thin pad. No induction or electromagnetic waves, the charge is made with energysquare's patented conduction charging technology.

Electrical properties of superconductor altered by stretching

Electrical properties of superconductor altered by stretching
In the early 1970s, the Cornell team of professors David Lee and Robert Richardson first observed superfluid helium-3. For that breakthrough, the catalyst for further research into low-temperature physics, the trio was awarded the 1996 Nobel Prize in physics. Twenty years later, another Cornell-led team has made an important discovery regarding the superconductor strontium ruthenate (Sr2RuO4,or SRO), often described as a crystalline analog of superfluid helium-3.

Li-ion battery stretches over skin to power wearables

Li-ion battery stretches over skin to power wearables
Researchers at Northwestern University and the University of Illinois at Urbana-Champaign have developed stretchable batteries that can be used to power a new generation of flexible electronics. The batteries will allow stretchable electronic devices to be used anywhere, including inside the human body where they could monitor anything from brain waves to heart activity, succeeding where flat, rigid batteries would fail.

Inverting DC/DC controller offers efficiencies up to 96%

Inverting DC/DC controller offers efficiencies up to 96%
Driving an all N-channel synchronous power MOSFET stage, the LTC3896 high voltage inverting switching regulator controller has been unveiled by Linear Technology. Most low to medium power inverting DC/DC converters utilise a coupled inductor or transformer. However, the LTC3896 uses only a single inductor and converts a 4V to 150V positive input voltage to a regulated negative output voltage from -60 to -0.8V at output currents up to 15A.

Design for flow battery could offer low cost and simplicity

Design for flow battery could offer low cost and simplicity
An approach to the design of a liquid battery, using a passive, gravity-fed arrangement similar to an old-fashioned hourglass, could offer great advantages due to the system's low cost and the simplicity of its design and operation, says a team of MIT researchers who have made a demonstration version of the new battery. Liquid flow batteries are not a new concept, and some members of this research team unveiled an earlier concept three years ago.

Eaton announces Intelligent Power Manager software version 1.52

Eaton announced the global launch of Intelligent Power Manager software version 1.52, which can be integrated with the VMware vRealize Operations platform. Now, datacentre and operations managers can use Eaton’s Intelligent Power Manager software and Infrastructure Management Pack to manage the health, risk and efficiency of their power devices and equipment similarly to how they use VMware vRealize Operations to manage their information technology devices in a software-defined datacentre.

Arduino shield speeds stepper motor system prototyping

Arduino shield speeds stepper motor system prototyping
Supporting the evaluation of motor driver devices as well as enabling, facilitating and accelerating customers' development, ROHM Semiconductor announces an Arduino-based evaluation kit. Designed as a ‘shield’ to plug directly into the Arduino main board, the EVK integrates ROHM's HTSSOP-B28 packaged stepper motor drive IC and complements the company’s support ecosystem, allowing engineers to rapidly prototype their stepper motor systems.
