Check out our Nature biomedical engineering paper on detecting otoacoustic emissions using smartphones and earphones and using it for new-born hearing screenin. https://www.nature.com/articles/s41551-022-00947-6
Ex-Ph.D. student, Vikram Iyer, was awarded the SIGMOBILE Doctoral Dissertation Award for “creative and inspiring work that shows how low-power sensing, computing and communication technologies can be used to emulate naturally-occurring biological capabilities.” Congrats Vikram on an inspiring Ph.D. thesis and joining UW CSE as professor Vikram is the third Read More ...
Since its inception, underwater digital acoustic communication has required custom hardware that neither has the economies of scale nor is pervasive. We present the first acoustic system that brings underwater messaging capabilities to existing mobile devices like smartphones and smart watches. Our software-only solution leverages audio sensors, i.e., microphones and Read More ...
Middle ear disorders are one of the most common causes of preventable hearing loss. Unfortunately, while the developing world bears a disproportionate burden of these disorders, it often lacks access to diagnostic tools. Tympanometry is a key test to measure middle ear function, but remains available only on expensive test Read More ...
Plants cover a large fraction of the Earth’s land mass despite most species having limited to no mobility. Many plants have evolved mechanisms to disperse their seeds using the wind. A dandelion seed, for example, can travel as far as a kilometer in dry, windy, and warm conditions. Inspired by Read More ...
Ever taken a phone call in a noisy environment? We built custom earbuds (MobiSys’22) which stream audio from both ears to your phone. We then run a neural net in real-time on the phone, isolating your voice while removing background noise. We also show superior noise suppression than Airpods Pro Read More ...
Frequent prothrombin time (PT) and international normalized ratio (INR) testing is critical for millions of people on lifelong anticoagulation with warfarin. Currently, testing is performed in hospital laboratories or with expensive point-of-care devices limiting the ability to test frequently and affordably. We report a proof-of-concept PT/INR testing system that uses Read More ...
We present DeepBeam, a hybrid model that combines traditional beamformers with a custom lightweight neural network. The former reduces the computational burden of the latter and also improves its generalizability, while the latter is designed to further reduce the memory and computational overhead to enable real-time and low-latency operations. Our Read More ...
