System and method for infrasonic cardiac monitoring

This invention describes a non-invasive system to continuously measure how much blood your heart pumps with each beat (stroke volume) and overall cardiac output. It uses a small sensor placed on the chest to detect subtle vibrations, specifically those between 5 and 25 Hz, caused by the heart's action. The system then applies a specific mathematical technique called wavelet packet functions, which have been pre-calibrated using data from many individuals, to interpret these chest movements and calculate the heart's performance.

Why it matters: Advances in machine learning and miniaturized MEMS sensors over the last decade simplify the complex signal processing and population-based calibration required for this system's 'learning tool' aspect.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedMEMS transducer, complex signal processing, population data
