Integrated Pacemaker System with Piezoelectric Energy Harvesting and Laser-Based Heartbeat Abnormality Detection

Abstract

Cardiovascular diseases remain the leading cause of mortality globally, highlighting the critical need for innovative cardiac care technologies. This study presents an advanced pacemaker system integrating piezoelectric energy harvesting, chemical sensors, and laser-based heartbeat abnormality detection. By converting body thermal and mechanical energy into electrical power, the system ensures continuous operation. The integration of diode laser sensors provides non-invasive, real-time monitoring of blood flow and oxygen saturation, enabling early detection of arrhythmias. A mobile application supports remote monitoring and emergency alerts, enhancing patient safety. The system's novel architecture aims to reduce surgical interventions and improve cardiac outcomes, setting a benchmark for future advancements in biomedical engineering.
