Heart Beat Detection Project using Emfit Matress sensor

snoring-project-image

Overview

Developing reliable methods to detect heartbeats using non-invasive EMFiT mattress sensors.

Background

Conventional heart monitoring can be intrusive, motivating alternative solutions embedded in everyday sleeping environments, mostly for screening purposes of heart disease, and sleep measurement (sleep architecture, quality, and stress / recovery analysis).

Aim

To accurately identify heartbeats from mattress sensor signals, ensuring comfort and minimal disruption.

Methods

Applying spectral analysis and NMF-based source separation techniques to isolate and demodulate heart pulse signals.

Results

Preliminary tests show promising accuracy in heartbeat detection, independent of patient position or movement.
