Design of Circuits & Systems for Healthcare Sensing Application

Abstract

The recent surge in healthcare sensing technologies has revolutionized the landscape of patient care and safety monitoring. This thesis delves into the burgeoning field of healthcare sensing and addresses the critical need for advancements in monitoring systems applicable to various domains, including elderly care, critical care units, and prolonged home monitoring. These applications necessitate the continuous and non-intrusive measurement of vital signs such as heart rate, blood-oxygen saturation, temperature, and subject movement. This research focuses on enhancing patient comfort and convenience by introducing innovative solutions. Firstly, the thesis introduces a receiver front-end integrated circuit (IC) tailored for radar systems enabling non-contact-based measurement of vital signs. This radar-based approach offers a non-invasive method for obtaining crucial health parameters, promising increased accuracy and reliability while minimizing patient discomfort. Furthermore, in response to the growing demand for portable safety systems in industrial settings, the thesis presents the development of a portable industry safety system. This system is designed to provide comprehensive safety monitoring in industrial environments, ensuring the well-being of workers through real-time monitoring and hazard detection. Through the exploration of these technological advancements, this thesis contributes to the field of healthcare sensing and safety systems. The proposed receiver front-end IC for radar-based vitals monitoring offers a novel approach to non-contact sensing, while the portable industry safety system aims to enhance workplace safety through continuous monitoring and hazard detection. Overall, these advancements pave the way for improved healthcare monitoring and industrial safety, addressing critical needs in both domains.
