The Department of Physics & Astrophysics is pleased to present a colloquium by Kouhyar Tavakolian, Assistant Professor of Electrical Engineering. “Cardiac Vibration Signals: New Tricks for Old Devices,” the colloquium will be held April 1 at 4 p.m. in Witmer Hall, Room 209.

With every heartbeat the body is set to a series of vibrations that can be recorded unobtrusively, using different sensing technologies and from different sites on the body. The techniques for recording these signals are not new, for the most part, and have been around for more than a century (e.g. seismocardiography and ballistrocardiography). However, new sensor and signal processing developments have provided us with a unique opportunity to use these techniques in monitoring cardiovascular dynamics. The applications range from monitoring patients during sleep, through sensors embedded in their beds or cloths, to adaptive adjustment of cardiac pacemakers. In this talk, an overview of these technologies and their novel applications will be presented.
