The gold standard for diagnosing sleep apnea — a disease which affects roughly 1 in 13 Americans — requires an overnight hospital stay and costs thousands of dollars. A new smartphone app developed at the University of Washington can wirelessly test for sleep apnea events in a person’s own bedroom without needing special sensors attached to the body.
Shyam Gollakota, a University of Washington assistant professor of computer science and engineering, has been named one of this year’s “Innovators Under 35” by global media company MIT Technology Review.
University of Washington engineers have designed a new communication system that uses radio frequency signals as a power source and reuses existing Wi-Fi infrastructure to provide Internet connectivity to battery-free devices.
University of Washington computer scientists have built a low-cost gesture recognition system that runs without batteries and lets users control their electronic devices hidden from sight with simple hand movements. The prototype, called “AllSee,” uses existing TV signals as both a power source and the means for detecting a user’s gesture command.
University of Washington engineers have created a new wireless communication system that allows devices to interact with each other without relying on batteries or wires for power.
University of Washington researchers have shown it’s possible to leverage Wi-Fi signals around us to detect specific movements without needing sensors on the human body or cameras.
