Carbon Nanotubes Make Big Push in Plasmonic Circuits
IEEE Spectrum - October 2017

"The field of plasmonics—which exploits the waves of electrons generated when photons strike a metal structure in order to carry out optoelectronic processes—has been building momentum in the research community over the past half decade. This interest is well placed. Plasmonics has made all sorts of interesting things possible, such as confining wavelengths of light to design smaller photonic devices. During that time, a range of two-dimensional materials, including black phosphorus and graphene, has enabled this growing interest. But the granddaddy of nanomaterials—the single-walled carbon nanotube—may still have a role to play in this exploding field."

'Near-Zero-Power' Temperature Sensor Could Make Wearables, Smart Home Devices Less Power-Hungry
UC San Diego - June 2017

"Electrical engineers at the University of California San Diego have developed a temperature sensor that runs on only 113 picowatts of power — 628 times lower power than the state of the art and about 10 billion times smaller than a watt. This "near-zero-power" temperature sensor could extend the battery life of wearable or implantable devices that monitor body temperature, smart home monitoring systems, Internet of Things devices and environmental monitoring systems.

The technology could also enable a new class of devices that can be powered by harvesting energy from low-power sources, such as the body or the surrounding environment, researchers said. The work was published in Scientific Reports on June 30."

IEEE Spectrum - June 2017

"Scientists in Thomas Jung’s research groups at the Paul Scherrer Institute (PSI) and at the University of Basel in Switzerland have fabricated the first two-dimensional ferrimagnetic material that consists of only two layers of material.

Two-dimensional magnetic structures have been hotly pursued in the research community because the magnetic properties of single molecules in these structures can be indivdually addressed and modified. This is especially important in spintronics, where the aim is to use the spins of electrons to encode information."

This Self-Poofing Fabric Transforms From T-Shirt to Parka
IEEE Spectrum - March 2017

"A small team at Otherlab, which does all kinds of weird things, has been using ARPA-E funding to develop what they're calling "thermally adaptive materials." We'll call it self-poofing fabric, for its ability to dynamically change its insulation in response to temperature. The idea is that the fabric will provide a small amount of insulation when it's warm out, and then increase how insulating it is (by trapping more air) in response to colder temperatures. When you see the prototype fabric in action, it looks like magic."

Heat-Sensitive Skin Could Let Prosthetics Feel Warmth
IEEE Spectrum - February 2017

"Many research groups around the world are developing flexible electronic skin for prosthetic limbs that can help replicate the sensory capabilities of real skin. When it comes to temperature, existing flexible sensors recognize changes of less than one-tenth of a degree C, but only within temperature ranges of less than 5 degrees C. Other flexible devices can work in wider temperature ranges, but are many times less sensitive.

Now scientists have developed an electronic skin that is sensitive to changes as little as one-hundredth of a degree C over a 45-degree range, from 5 °C to 50 °C. This sensitivity is comparable to that of pit vipers such as rattlesnakes, the researchers say. In comparison, human skin is only sensitive to changes of about two-hundredths of a degree C, the scientists add."
