Apple and Q-Dots.

While we know that Apple’s next display shift will be to OLED for their 2017 Anniversary edition iPhone, Apple is always looking to the next wave technology just on the horizon. So what’s beyond OLED? At the moment, many think the next trend points to Quantum Dot LED or QDLED. While the structure of a QLED is very similar to OLED technology, the difference is that the light emitting centers are cadmium selenide nanocrystals, or quantum dots. Theoretically, the advantages to this type of display is that it could reportedly deliver brighter ‘pure color’ and consumes less power, in fact close to 50% less power. The technology is also ideal for consumer devices that demand a flexible display. When Apple first introduced their vision of an Apple Watch in 2013, they presented it with a ‘continuous’ display that completely wraps around a users wrist as noted in the patent figure below. A QDLED type of display would allow such a form factor to come to market.

While Quantum Dot based displays are no doubt many years out, Apple is already on record having explored the technology in a string of four patent filings that we covered back in 2014 in a report titled “Quantum Dots Could Take the Retina Display to the Next Level.” Today, another Quantum Dot invention came to light.

Computers use switches to perform calculations. A complex film with “quantum wells”—regions that allow electron motion in only two dimensions—can be used to make efficient switches for high-speed computers. For the first time, this oxide film exhibited a phenomenon, called resonant tunneling, in which electrons move between quantum wells at a specific voltage. This behavior allowed an extremely large ratio (about 100,000:1) between two states, which can be used in an electronic device as an ON/OFF switch to perform mathematical calculations (Nature Communications, “Resonant tunneling in a quantum oxide superlattice”).

Quantum wells

Efficient control of electron motion can be used to reduce the power requirements of computers. “Quantum wells” (QW) are regions that allow electron motion in only two dimensions. The lines (bottom) in the schematic show the probability of finding electrons in the structure. The structure is a complex oxide (top) with columns (stacked blue dots corresponding to an added element) where the electrons are free to move in only two dimensions. This is a special type of quantum well called a two-dimensional electron gas (2DEG). (Image: Ho Nyung Lee, Oak Ridge National Laboratory)

To meet our exponentially growing need for computing power without a corresponding jump in energy use, scientists need more efficient electronic versions of switches to perform calculations. Efficient switches need materials that switch between well-defined ON/OFF states. The results of this study could lead to a new class of energy-efficient electronics because these materials can ensure the electronic switches are ON or OFF. These electronic switches could lower power consumption in electronics enabling, for example, the development of high-speed supercomputers and cell phones with longer battery life.

We spend our lives surrounded by high-tech materials and chemicals that make our batteries, solar cells and mobile phones work. But developing new technologies requires time-consuming, expensive and even dangerous experiments.

Luckily we now have a secret weapon that allows us to save time, money and risk by avoiding some of these experiments: computers.

Thanks to Moore’s law and a number of developments in physics, chemistry, computer science and mathematics over the past 50 years (leading to Nobel Prizes in chemistry in 1998 and 2013) we can now carry out many experiments entirely on computers using modeling.

Storage tech doesn’t get much better than this. Scientists at TU Delft have developed a technique that uses chlorine atom positions as data bits, letting the team fit 1KB of information into an area just 100 nanometers wide. That may not sound like much, but it amounts to a whopping 62.5TB per square inch — about 500 times denser than the best hard drives. The scientists coded their data by using a scanning tunneling microscope to shuffle the chlorine atoms around a surface of copper atoms, creating data blocks where QR code -style markers indicate both their location and whether or not they’re in good condition.

Not surprisingly, the technology isn’t quite ready for prime time. At the moment, this storage only works in extremely clean conditions, and then only in extreme cold (77 kelvin, or −321F). However, the approach can easily scale to large data sizes, even if the copper is flawed. Researchers suspect that it’s just a matter of time before their storage works in normal conditions. If and when it does, you could see gigantic capacities even in the smallest devices you own — your phone could hold dozens of terabytes in a single chip.

Lumee™ tissue-O2 monitoring system slated to be available this year in Europe

SOUTH SAN FRANCISCO, Calif., May 16, 2016 — Profusa, Inc. announced today that it was selected by Pioneers, the global business relationship builder, to showcase the company’s “wear-and-forget” Lumee™ biosensor technology at the Pioneers Festival held at the prestigious Hofburg Imperial Palace in Vienna, Austria, May 24th-25th.

Making health and disease monitoring as easy as turning on your smart phone, the company’s tissue-integrated sensors for long-term, continuous tracking of body chemistry will be highlighted by Ben Hwang, Profusa’s chairman and chief executive officer, in a talk entitled, “Beyond Fitness Trackers: Let Your Body Speak.”

BTW — In 1999, I told a guy from Diamond Intl. that the thread in our clothing would be able to do this in the next 15 to 20 years. He laughed at me; never say never.

For the first time, researchers led by Tufts University engineers have integrated nano-scale sensors, electronics and microfluidics into threads — ranging from simple cotton to sophisticated synthetics — that can be sutured through multiple layers of tissue to gather diagnostic data wirelessly in real time, according to a paper published online July 18 in Microsystems & Nanoengineering. The research suggests that the thread-based diagnostic platform could be an effective substrate for a new generation of implantable diagnostic devices and smart wearable systems.

The researchers used a variety of conductive threads that were dipped in physical and chemical sensing compounds and connected to wireless electronic circuitry to create a flexible platform that they sutured into tissue in rats as well as in vitro. The threads collected data on tissue health (e.g. pressure, stress, strain and temperature), pH and glucose levels that can be used to determine such things as how a wound is healing, whether infection is emerging, or whether the body’s chemistry is out of balance. The results were transmitted wirelessly to a cell phone and computer.

Smartphones and tablets are being used more frequently in the battlefield, and that means that battery power is more important than ever. Soldiers often carry spare battery chargers in the 90-pound combat packs they carry into war zones, but the batteries are often lost or broken. BAE Systems wants to help lighten the load with its new system that lets soldiers plug electronics directly into their clothing.

The BAE Systems Broadsword Spine is a harness that can be sewn into a soldiers vest, jacket, or belt that carries a battery pack and hides charging wires. The harness places the battery pack on the small of a soldier’s back and includes eight conductive fabric conduits that can be used to connect to a USB port.
