Optics & Photonics News reporter Patricia Daukantas spotlights how a team of researchers from the Singapore-MIT Alliance for Research and Technology (SMART) has uncovered a way to generate long wavelength light using intrinsic defects in semi-conducting materials. “The new method raises the possibility of future CMOS-compatible LEDs that give off the full spectrum of visible light, writes Daukantas, “without the need for phosphors that generate excess heat and shorten the diodes’ lifespan.”

Via Separations, a startup co-founded by Shreya Dave ’16 and Brent Keller ’16 after conducting research with MIT Professor Jeffrey Grossman, has announced a $38 million Series B led by NGP ETP, reports Ron Miller for TechCrunch. “Basically, our vision is if we can decarbonize that supply chain infrastructure, then we don’t have to rely on consumers having to make a decision between the thing that they want and how to do good for the planet” says Dave.  

Mashable reporter Emmett Smith spotlights how MIT researchers have created a new toolkit for designing wearable devices that can be 3D printed. “The researchers used the kit to create sample devices, like a personal muscle monitor that uses augmented reality,” explains Smith, “plus a device for recognizing hand gestures and a bracelet for identifying distracted driving.”

Forbes contributor David Blackmon spotlights Ambri, an MIT startup that is developing liquid-metal batteries. Blackmon writes that Ambri has developing a new battery technology that could “help renewables like wind and solar scale up more rapidly in the coming years and help them occupy a larger share of electricity generation around the world.”

Washington Post columnist David Von Drehle spotlights MIT startup Form Energy, which has created a battery prototype made of iron and oxygen that stores large amounts of power and can release it over days. Von Drehle writes that this new battery could usher in a “sort of tipping point for green energy: reliable power from renewable sources at less than $20 per kilowatt-hour.”

Wall Street Journal reporter Russell Gold spotlights how Form Energy, a startup co-founded by Prof. Yet-Ming Chiang, has developed an inexpensive iron-air battery that can discharge power for days. The batteries could be “capable of solving one of the most elusive problems facing renewable energy: cheaply storing large amounts of electricity to power grids when the sun isn’t shining and wind isn’t blowing,” writes Gold.

MIT researchers are developing an electronic skin that can withstand sweating, reports Karen Kwon for Inside Science. The researchers “punched holes on the e-skin to match the size of sweat pores and the distance between them. Then, inspired by kirigami, the team cut away even more material between two holes in an alternating pattern,” writes Kwon. The resulting pattern “could tolerate bending and stretching more than the conventional e-skin with simple holes.”

Provost Marty Schmidt speaks with TopUniversities.com reporter Chloe Lane about how MIT has maintained its position as the top university in the world on the QS World University Rankings for 10 consecutive years. “I am honored to have been a part of the MIT community for almost 40 years,” says Schmidt. “It’s a truly interdisciplinary, collaborative, thought-provoking place that encourages experimentation and pushes you to expand your mind. I think it’s a wonderful place to call home.”

MIT researchers have developed new programmable fibers that could help transform clothing into wearable computers, reports Kyle Mizokami for Popular Mechanics. “The polymer fibers contain hundreds of tiny silicon microchips that, once electrified, can sustain a digital connection across tens of meters,” Mizokami writes.

Forbes contributor Eric Tegler spotlights how MIT researchers are developing a fiber with digital capabilities. “Individuals wearing garments with digital fibers could be alerted to vital information about their physiology and environmental exposures, and share health/injury and location data with support forces,” Tegler explains.

Researchers from the Singapore-MIT Alliance for Research and Technology (SMART) have found that twisting crystal films can be used to control light emissions from materials, reports Steve Bush for ElectronicsWeekly.com.

Washington Post reporter Dalvin Brown spotlights Nextiles, a company spun out of MIT and the NSF that has crafted machine-washable smart fabrics that capture biometric data. “Just imagine all the biochemicals that come out of you and get released into your clothes,” says Prof. Yoel Fink of the future of e-textiles. “Today, all of that stuff gets erased in the washing machine. But at some point, your fabric could learn, listen to subtle changes, and alert you to go to the doctor for a checkup.”

Profs. Elsa Olivetti and Christopher Knittel speak with J.D. Allen of WSHU about the future of renewable energy in New England. Olivetti notes that the MIT Climate & Sustainability Consortium is aimed at “looking at the role of industry in helping to accelerate the transition to reduce carbon emissions, and the idea is that by convening a set of cross economy, leading companies with the MIT community, we can identify pathways towards decarbonization particularly focused on those industries outside of the energy producing sector.”

CSAIL researchers have developed a new material with embedded sensors that can track a person’s movement, reports Mashable. The clothing could “track things like posture or give feedback on how you’re walking.”

UPI reporter Brooks Hays writes that MIT researchers have developed a new technique for turning plastic into a wearable material. “Engineers at MIT have managed to weave polyethylene into fibers that absorb and evaporate water more quickly than cotton, nylon, polyester and other common textiles,” writes Hays. “The authors of the new paper hope their technology will incentivize plastic recycling.”
