Large Area Ballistocardiography Enabled by Printed Piezoelectric Sensor Arrays on Elastomeric Substrates

Advanced Materials Technologies, Volume 9, Issue 17, September 4, 2024.
Ballistocardiography (BCG) studies ballistic forces on the body generated during a heartbeat. As it is an unobtrusive detection method, that requires sensors measuring small dynamic forces. Piezoelectric sensors are ideal, but improvements in sensitivity
