Carnegie Mellon University’s Maysam Chamanzar and his team have invented an optical platform that will likely become the new standard in optical biointerfaces. He’s labeled this new field of optical technology “Parylene photonics,” demonstrated in a recent paper in Nature Microsystems and Nanoengineering.

There is a growing and unfulfilled demand for optical systems for biomedical applications. Miniaturized and flexible optical tools are needed to enable reliable ambulatory and on-demand imaging and manipulation of biological events in the body. Integrated photonic technology has mainly evolved around developing devices for optical communications...

Scientists have come a step closer to the vision of a broad application of flexible, printable electronics. The team has succeeded in developing powerful vertical organic transistors with two independent control electrodes.

High-definition roll-up televisions or foldable smartphones may soon no longer be unaffordable luxury goods that can be admired at international electronics trade fairs...

Engineers have invented a soft wearable device which simulates the sense of touch and has wide potential for medical, industrial and entertainment applications. What if you could touch a loved one during a video call — particularly in today’s social distancing era of COVID-19 — or pick up and handle a virtual tool in a video game?

Pending user tests and funding to commercialise the new technology, these ideas could become reality in a couple of years after UNSW Sydney engineers developed a new haptic device which recreates the sense of touch.

Haptic technology mimics the experience of touch by stimulating localised areas of the skin in way...

New technology lets Quantum Bits hold Information for 10,000 times Longer than previous record

Conceptual art of the acceptor-based spin-orbit qubit. A boron atom (yellow) implanted in silicon crystal (blue) bounds a hole. Orbital motion of a hole in silicon is coupled to its spin degree of freedom. This coupling is reminiscent of gears where circular motion (blue arrow) and spinning (red arrow) are locked together. Quantum information is encoded to the combined motion and spin of a hole in the spin-orbit qubit. â’¸Takashi Kobayashi, Tohoku University

Quantum bits, or -qubits, can hold quantum information much longer now thanks to efforts by an international research team. The researchers have increased the retention time, or coherence time, to 10 milliseconds – 10,000 times longer than the previous record – by combining the orbital motion and spinning inside an atom...
