Google published a research paper that details a new experimental technology that can turn any existing ANC earbuds into cardiac monitors through a software update without the need for any hardware.
In the research study titled “APG: Audioplethysmography for Cardiac Monitoring in Hearables,” the tech giant describes the technology as “a novel cardiac monitoring modality” that can be used with off-the-shelf hearables. This new approach relies on audioplethysmography — or APG, for short — which uses ultrasound techniques to measure heart rate.
