About the book

We are living in a society where automation in each electrical appliance/instrument is a great demand. We wish to have automatic devices/gadgets/instruments with no or minimal intervention from humans in their daily operation. Then only, these devices can qualify to call it is smart instruments. To fulfill this, one of the major requirements is to come up with highly sensitive, long-lasting, low-cost smart sensors. On the other hand, the healthcare industry demands low-cost, Lab-on-chip type biosensors for simple and rapid detection of various biomolecules or biogases. A sensor is an analytical device that detects the change in the environment and responds to some output in terms of a measurable analog resistance/voltage/current converted into a human-readable display or transmitted for further processing. In the last two decades, a significant amount of research has been devoted to the development of various types of gas sensors using different nanomaterials in the electronic and healthcare industry.

This book aims to provide the reader (research scholars, scientists, and engineers working in the field of sensors) an overview of the recent advances made in the development of various gas sensors for the electronic and healthcare industries for the betterment of the human lifestyle. Also, this book will intend to address existing challenges and a few future directions of research for easy integration and cost-effective fast sensing of such
gas sensors.
