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.

MilliMobile is a tiny, self-driving robot powered only by light and radio waves

Two fingers are about to pick up a tiny robot

The robot, equipped with a solar panel–like energy harvester and four wheels, is about the size of a penny, weighs as much as a raisin and can move about the length of a bus in an hour on a cloudy day.

Tiny battery-free devices float in the wind like dandelion seeds

Inspired by how dandelions use the wind to distribute their seeds, a University of Washington team has developed a tiny sensor-carrying device that can be blown by the wind as it tumbles toward the ground.

Faculty/staff honors: Grants for STEM equity, HIV prevention; innovation award — and a White House honor for engineering mentoring

Eve Riskin, professor and associate dean in the UW College of Engineering, has been named a recipient of a 2019 Presidential Award for Excellence in Science, Mathematics and Engineering Mentoring.

Recent honors and grants to University of Washington individuals and units have come from the National Science Foundation, National Institutes of Health, the Marconi Society — and the White House.

Researchers create first sensor package that can ride aboard bees

the sensor backpack

Farmers can already use drones to soar over huge fields and monitor temperature, humidity or crop health. But these machines need so much power to fly that they can’t get very far without needing a charge. Now, engineers at the University of Washington have created a sensing system that is small enough to ride aboard a bumblebee.

Engineers at the University of Washington have developed 3D printed devices that can track and store their use — without using batteries or electronics. Instead, this system uses a method called backscatter, through which a device can share information by reflecting signals that have been transmitted to it with an antenna.

In first, 3-D printed objects connect to WiFi without electronics

UW engineers have developed the first 3-D printed plastic objects that can connect to other devices via WiFi without using any electronics, including a laundry bottle that can detect when soap is running low and automatically order more.
