A team led by researchers at the Ä¢¹½ÊÓÆµ developed a new PCB that performs on par with traditional materials and can be recycled repeatedly with negligible material loss. Researchers used a solvent that transforms a type of vitrimer — a cutting-edge class of polymer — into a jelly-like substance without damage, allowing solid components to be plucked out for reuse or recycling. With these “vPCBsâ€� (vitrimer printed circuit boards), researchers recovered 98% of the vitrimer and 100% of the glass fiber.

Ä¢¹½ÊÓÆµ researchers introduced the Thermal Earring, a wireless wearable that continuously monitors a user’s earlobe temperature. Potential applications include tracking signs of ovulation, stress, eating and exercise. The smart earring prototype is about the size and weight of a small paperclip and has a 28-day battery life.

In a proof-of-principle study, Ä¢¹½ÊÓÆµ and University of California San Diego researchers have shown that smartphones are capable of detecting blood oxygen saturation levels down to 70%. This is the lowest value that pulse oximeters should be able to measure, as recommended by the U.S. Food and Drug Administration.

A Ä¢¹½ÊÓÆµ-led team has developed a method that uses the camera on a person’s smartphone or computer to take their pulse and breathing rate from a real-time video of their face.

The Ä¢¹½ÊÓÆµ and Tsinghua University have agreed to launch an integrated dual degree program through the Global Innovation Exchange (GIX) that combines project-based learning in design thinking, technology development and entrepreneurship.

Peering into a grocery store bin, it’s hard to tell if a peach or tomato or avocado is starting to go bad underneath its skin. A new affordable hyperspectral camera technology developed by Ä¢¹½ÊÓÆµ and Microsoft Research uses both visible and invisible near-infrared light to “see” beneath surfaces and capture hidden details.
