Abstract:

The lecture will present a short history of wearables and photoplethysmography (PPG), hypotheses related to origins of PPG, PPG sensors and novel integrated wearable device KTU_watch, which was already used in numerous research projects.

PPG signals are convenient to register but they present many challenges due to signal quality and artifacts. Nevertheless, these signals are promising for long-term unobtrusive monitoring of cardiac arrhythmia, blood pressure, mental stress, and pain.
