This book provides a combined effect and an in-depth exploration of how advanced materials and energy-harvesting technologies create smarter and more adaptive sensing device. Self-powered gas sensors have become a cornerstone of modern technological innovation, finding critical utilities in various sectors ranging from medical and environmental monitoring to industrial safety and smart agriculture. The future demands of gas sensors not only depend on its efficiency and sensitivity but also lie in the fabrication of devices that are flexible, environmental friendly, and self-powered.
Dr. Neeraj Dhariwal is currently a dedicated researcher with the Department of Physics at Netaji Subhas University of Technology (NSUT), New Delhi. He earned his Ph.D. in Physics from NSUT, where his doctoral work laid the foundation for his ongoing research in advanced functional materials. His research primarily focuses on the design, synthesis, and development of advanced materials for thermoelectric devices and sensor technologies, particularly in the fields of gas sensing and humidity sensing. In addition to sensors, Dr. Dhariwal is actively involved in the development of energy-based advanced materials, contributing to the advancement of energy-efficient technologies and smart sensing systems. His multidisciplinary approach bridges material science, applied physics, and engineering applications, addressing pressing global challenges in environmental monitoring and sustainable energy.
