Spin current from heat: new material increases efficiency
Spin current from heat: new material increases efficiency

Physicists at Bielefeld University have found a way to use the heat from electronic devices to create energy, applying the heat to generate magnetic signals known as ‘spin currents’. According to researchers it could be possible in the future to use these signals to replace some of the electrical current currently used in electronic components. In a new study, physicists from the University of Greifswald, Gießen University, and the Leibniz Institute for Solid State and...

Breakthrough in organic electronics
Breakthrough in organic electronics

Work by researchers from Princeton University, the Georgia Institute of Technology and Humboldt University in Berlin is pointing the way to possibly more widespread use of organic electronics. Their research, which was recently published in Nature Materials, focuses on organic semiconductors, a class of materials for seen as being used in emerging technologies such as flexible electronics, solar energy conversion, and high-quality colour displays. In the short term, the advance could he...

Researchers develop smart, ultra-thin microfibre sensor
Researchers develop smart, ultra-thin microfibre sensor

A research team at the National University of Singapore (NUS) has developed a soft, flexible and stretchable microfibre sensor for real-time healthcare monitoring and diagnosis. Highly sensitive and ultra-thin with a diameter of a strand of human hair, the sensor has been designed to be both simple and cost-effective to mass produce. While wearable and flexible technology has gained significant interest in recent years, current devices have various limitations – for instance, they...

Nanoscale magnetic circuit moves data in 3D
Nanoscale magnetic circuit moves data in 3D

Researchers at the University of Cambridge, working with a team from TU Eindhoven, have used 3D nanoprinting to create a nanoscale magnetic circuit which is said to be capable of moving information in three dimensions. The team claims this could lead to an ‘important increase’ in storage and processing capacities. “We have demonstrated a new way to fabricate and use a magnetic device which, in a nanometric scale, can controllably move information along the three dimension...

Imec and Panasonic develop innovative nanocomposite electrolyte

Imec and Panasonic have announced that they have developed a solid nanocomposite electrolyte for next-generation batteries with a lithium ion conductivity several times greater than its liquid equivalent. The ion conductivity already reaches several mS/cm at room temperature and imec and Panasonic have set a goal to develop innovative solid nanocomposite electrolyte materials towards 100mS/cm in the next few years, which would make them suitable for fast-charging high-energy cells for use ...
