Wi-Fi Could Help Identify When You're Struggling to Breathe
Working with colleagues at the Office of Science and Engineering Labs (OSEL) in the FDA’s Center for Devices and Radiological Health, researchers advanced a way to use Wi-Fi routers to measure the breathing rate of a person in the room.

Researchers led by U.S. National Institute of Standards and Technology scientists developed the BreatheSmart algorithm to analyze a person's movements and determine whether they have difficulty breathing via Wi-Fi routers and devices.
The researchers tweaked the firmware on a Wi-Fi router to request channel state information (CSI) up to 10 times per second to receive a detailed picture of how such data was changing.
The researchers had a medical training manikin mimic various breathing conditions, its chest movements altering the path traveled by the Wi-Fi signal.
The BreatheSmart algorithm applied deep learning to process this data, and classified respiratory patterns simulated by the manikin with 99.54% accuracy.
