BMAR: Barometric and Motion-based Alignment and Refinement for Offline Signal Synchronization across Devices
Manuel Meier, Christian Holz
A requirement of cross-modal signal processing is accurate signal alignment. Though simple on a single device, accurate signal synchronization becomes challenging as soon as multip…
Tri-Spectral PPG: Robust Reflective Photoplethysmography by Fusing Multiple Wavelengths for Cardiac Monitoring
Manuel Meier, Berken Utku Demirel, Christian Holz
Multi-channel photoplethysmography (PPG) sensors have found widespread adoption in wearable devices for monitoring cardiac health. Channels thereby serve different functions -- whe…
Robust Heart Rate Detection via Multi-Site Photoplethysmography
Manuel Meier, Christian Holz
Smartwatches have become popular for monitoring physiological parameters outside clinical settings. Using reflective photoplethysmography (PPG) sensors, such watches can non-invasi…
Respiro: Continuous Respiratory Rate Monitoring During Motion via Wearable Ultra-Wideband Radar
Sebastian Reidy, Manuel Meier, Christian Holz
Deviations in respiratory rate often precede abnormalities in other vital signs. However, continuously monitoring respiratory rates outside clinical settings remains challenging du…
