Design of Low-Power Electronic Circuits & Systems for Point of Care Healthcare Applications

Abstract

The thesis entitled ”Design of Low-Power Electronic Circuits & Systems for Point of Care Healthcare Applications” focuses on the development of a cutting-edge point of care device tailored for deployment in remote and resource-constrained settings. The impetus for this project stems from the urgent need to extend quality healthcare services in areas where conventional, cumbersome, and expensive medical equipment is untenable. Engineered for efficiency and ease of use, the device is characterized by its low power consumption and portability, making it well-suited for environments with sparse access to electrical power and established medical facilities. The core technology utilizes Electrical Impedance Spectroscopy (EIS) integrated with vital signs monitoring to detect physiological changes indicative of health conditions that require immediate medical attention. This dual functionality not only enables the early detection of critical health issues but also promotes timely medical interventions, significantly enhancing patient outcomes. This research further encompasses the innovative design of an active high pass filter within the analog baseband chain of the device’s integrated circuit. These components are specifically tailored for use in Frequency Modulated Continuous Wave (FMCW) radar systems, which form part of the receiver design to accurately detect heart and respiratory rates. Comprehensive evaluation of the device throughout the research confirms its effectiveness in meeting the healthcare delivery needs of isolated regions. The findings highlight the transformative potential of such devices in improving healthcare accessibility and efficacy across underserved populations. This device emerges as a vital instrument in the global initiative to enhance healthcare delivery, demonstrating significant implications for the future of remote medical practices and technology-driven health interventions.
