Engineers at the University of California San Diego have developed the first flexible wearable device capable of monitoring both biochemical and electric signals in the human body. The Chem-Phys patch records electrocardiogram (EKG) heart signals and tracks levels of lactate, a biochemical that is a marker of physical effort, in real time. The device can be worn on the chest and communicates wirelessly with a smartphone, smart watch or laptop. It could have a wide range of applications, from athletes monitoring their workouts to physicians monitoring patients with heart disease.

Nanoengineers and electrical engineers at the UC San Diego Center for Wearable Sensors worked together to build the device, which includes a flexible suite of sensors and a small electronic board. The device also can transmit the data from biochemical and electrical signals via Bluetooth.

Nanoengineering professor Joseph Wang and electrical engineering professor Patrick Mercier at the UC San Diego Jacobs School of Engineering led the project, with Wang’s team working on the patch’s sensors and chemistry, while Mercier’s team worked on the electronics and data transmission. They describe the Chem-Phys patch in the May 23 issue of Nature Communications.

Love this; Congrats to Michelle Simmons and her work on QC — Superstar females in STEM.

For her world-leading research in the fabrication of atomic-scale devices for quantum computing, UNSW Australia’s Scientia Professor Michelle Simmons has been awarded a prestigious Foresight Institute Feynman Prize in Nanotechnology.

Two international Feynman prizes, named in honour of the late Nobel Prize winning American physicist Richard Feynman, are awarded each year in the categories of theory and experiment to researchers whose work has most advanced Feynman’s nanotechnology goal of molecular manufacturing.

Professor Simmons, director of the UNSW-based Australian Research Council Centre of Excellence for Quantum Computation and Communication Technology, won the experimental prize for her work in “the new field of atomic-electronics, which she created”.

Establishing the trend. Q-dot technology will be in all displays soon.

“Samsung Electronics will skip commercializing OLED for TVs and ho straight to QLED technology, perhaps as soon as 2009. Its strategy is to continue to develop its quantum-dot TVs, which are its current major products, and prepare to commercialize QLED technologies during this time.”

The physical limitations of existing materials are one of main problems when it comes to flexible electronics, be it wearables, medical or sports tech. If a flexible material breaks, it either stays broken, or if it has some self-healing properties it may continue to work, but not so well. However, a team from Penn State have creating a self-healing, flexible material that could be used inside electronics even after multiple breaks.

The main challenge facing researchers led by Professor Qing Wang, was ensuring that self-healing electronics could restore “a suite of functions”. The example used explains how a component may still retain electrical resistance, but lose the ability to conduct heat, risking overheating in a hypothetical wearable, which is never good. The nano-composite material they came up with was mechanically strong, resistant against electronic surges, thermal conductivity and whilst packing insulating properties. Despite being cut it in half, reconnecting the two parts together and healing at a higher temperature almost completely heals where the cut was made. The thin strip of material could also hold up to 200 grams of weight after recovering.

New method for precisely identifying and treating fractures.

You’ve injured your knee. A doctor straps a listening device to it, and the noises you hear coming out of it are cringe-worthy. “Crackle! Krglkrglkrgl! Snap!”

Your isn’t breaking; it’s only bending, and in the future, those sounds could help doctors determine whether the convalescing joint is healthy yet, or if it needs more therapy.

Yesterday, we saw the news from D-Wave in development & release of a new scalable QC. Now, Dartmouth has been able to develop a method to design faster pulses, offering a new way to accurately control quantum systems.

Dartmouth College researchers have discovered a method to design faster pulses, offering a new way to accurately control quantum systems.

The findings appear in the journal Physical Review A.

Quantum physics defines the rules that govern the realm of the ultra-small — the atomic and sub-atomic world — which explains the behavior of matter and its interactions. Scientists have been trying to exploit the seemingly strange properties of this quantum world to build practical devices, such as ultra-fast computers or ultra-precise quantum sensors. Building a practical device, however, requires accurately controlling your device to make it do what you want. This turns out to be challenging since quantum properties are very fragile.

Light waves might be able to drive future transistors. The electromagnetic waves of light oscillate approximately one million times in a billionth of a second, hence with petahertz frequencies. In principle also future electronics could reach this speed and become 100.000 times faster than current digital electronics. This requires a better understanding of the sub-atomic electron motion induced by the ultrafast electric field of light. Now a team of the Laboratory for Attosecond Physics (LAP) at the Max-Planck Institute of Quantum Optics (MPQ) and the Ludwig-Maximilians-Universität (LMU) and theorists from the University of Tsukuba combined novel experimental and theoretical techniques which provide direct access to this motion for the first time.

Electron movements form the basis of electronics as they facilitate the storage, processing and transfer of information. State-of-the-art electronic circuits have reached their maximum clock rates at some billion switching cycles per second as they are limited by the heat accumulating in the process of switching power on and off.

The electric field of light changes its direction a trillion times per second and is able to move electrons in solids at this speed. This means that light waves can form the basis for future electronic switching if the induced electron motion and its influence on heat accumulation is precisely understood. Physicists from the Laboratory for Attosecond Physics at the MPQ and the LMU already found out that it is possible to manipulate the electronic properties of matter at optical frequencies.

HP has announced that they will be releasing their first generation 3D printers by the end of the year. The Multi Jet Fusion Technology allows 3D printing at half the cost and ten times the speed.

HP has released two new 3D printer models, the Jet Fusion 3200 and Jet Fusion 4200—their first products on the market since the company entered the 3D printing arena in 2014. These high-end printers do not need lasers (like most rivals in their range) and will be available by the end of the year.

Not only will the printers be able to print at half the cost and ten times the speed of other printers on the market, but to top it all off, they can produce sharp, fine, high-definition edges.
