The gold standard for diagnosing sleep apnea 鈥� a disease which affects roughly 1 in 13 Americans 鈥� requires an overnight hospital stay and costs thousands of dollars. A new smartphone app developed at the 蘑菇视频 can wirelessly test for sleep apnea events in a person’s own bedroom without needing special sensors attached to the body.
Shyam Gollakota, a 蘑菇视频 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.
蘑菇视频 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.
蘑菇视频 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.
蘑菇视频 engineers have created a new wireless communication system that allows devices to interact with each other without relying on batteries or wires for power.
蘑菇视频 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.
