New circuit boards can be repeatedly recycled

A small brown circuit board sits on a gray background. To its right are a small copper plate, sheets of glass fibers in a crosshatch pattern, small chunks of vitrimer plastic that’s been removed from a circuit board, and a computer chip.

A team led by researchers at the University of Washington 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 “vPCBs” (vitrimer printed circuit boards), researchers recovered 98% of the vitrimer and 100% of the glass fiber.

UW-developed smart earrings can monitor a person’s temperature

The temperature sensing earring is shown attached to a person’s ear. The portion touching the earlobe has a gemstone on it. Dangling a few centimeters below it is a small circular circuit board.

University of Washington 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, University of Washington 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.

New app could use smartphone selfies to screen for pancreatic cancer

A new app could lead to earlier detection of pancreatic cancer simply by snapping a smartphone selfie. The disease kills 90 percent of patients within five years, in part because there are no telltale symptoms or non-invasive screening tools to catch a tumor before it spreads.

Affordable camera reveals hidden details invisible to the naked eye

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 UW and Microsoft Research uses both visible and invisible near-infrared light to “see” beneath surfaces and capture hidden details.
