In this thesis, a portable-based cardiac monitoring system is discussed, which helps to keep a check on the corresponding patient vitals. This work describes the design and development of a Bluetooth system, incorporating a piezoelectric sensor-sheet. The demonstrated prototype avoids the need for collecting the signals with wires. When the Bluetooth-connected piezoelectric sensor is attached to the human chest, the cardiac mechanical activity will induce a local strain in the active piezoelectric materials layer. This strain is converted to an electrical output voltage which is then collected and transmitted through the Bluetooth system. Piezoelectric theory and signal processing methods are used to extract the cardiac parameters from the output voltage signal. These parameters have been validated using the conventional cardiac cycle based meters. This wireless cardiac monitoring system can find a wide range of applications due to its compactness, light weight, and reliability.
