"Transforming ANC Earbuds: Google's Innovative Heart Rate Monitor Solution"

Google's research team has developed a technology called APG that can convert existing off-the-shelf ANC earbuds into heart rate monitors through a software upgrade. The technology uses audioplethysmography (APG) to measure heart rate by bouncing a low-density ultrasound signal off the inside of the ear canal. It works even while music is playing and does not impact the earbuds' battery life. Google conducted a field study with 153 participants and found that the APG approach maintains a high level of accuracy. Future research will focus on testing the technology in more rigorous physical activities.

"Google's Innovative Tech Transforms ANC Earbuds into Heart Rate Monitors"

Google has developed a new technology called APG that can turn any existing active noise-canceling (ANC) earbuds into cardiac monitors. By utilizing an acoustic sensing system, APG sends ultrasound probing signals through the earbuds' speakers and analyzes the echoes received via the onboard microphones to measure heart rate and heart rate variability. Google conducted an eight-month field study with 153 participants, demonstrating high accuracy in reporting heart rate readings and minimal impact on battery life. The research team plans to further test APG with rigorous motion activities to improve its performance and explore its potential for other health research.

"Google's ANC Earbuds Transformed into Heart Rate Sensors"

Google has revealed its research into using audioplethysmography (APG) to add heart rate sensing capabilities to active noise canceling (ANC) headphones and earbuds through a simple software upgrade. By sending a low intensity ultrasound probing signal through the speakers, the ear canal's deep artery can be used to measure heart rate and heart rate variability. Google's studies found that APG achieves consistently accurate heart rate and heart rate variability measurements, regardless of skin tones or ear canal size. This approach eliminates the need for additional hardware and offers new possibilities for low-cost health sensing. However, it is uncertain if this technology will be implemented in Pixel Buds.
