Demonstration Abstract: BioWatch - a Wrist Watch based Physiological Signal Acquisition System Conference Paper uri icon


  • A wrist watch based system, which can measure electrocardiogram (ECG) and photoplethysmogram (PPG), is presented in this work. By using both ECG and PPG we measure pulse transit time (PTT), which is known to correlate well with the blood pressure (BP) [1]. This system, called BioWatch, can potentially facilitate continuous and ubiquitous monitoring of ECG, PPG and BP. © 2014 IEEE.
