Smart Sensors for Biomedical Applications: Design and Testing using VLSI Technologies

Abstract

By means of very large scale integration (VLSI) technologies, they have been rapidly developed as smart sensors for biomedical applications. These innovative devices are eliminating intrusiveness and thereby transforming healthcare by providing continuous monitoring, early diagnosis and targeted treatment. This article covers the VLSI smart sensors for biomedical field and brings the cutting edge design approaches, the testing methodologies and the emerging trends in it.As healthcare costs continue to increase, populations age, and, as a result, medical cost efficiency will become more and more important. potentials VLSI technologies are that of miniaturized, low power sensors that can easily embedded into wearable devices, implants and diagnostic tools. So, these smart sensors capture, relate and transmit the vital physiological data to more accurate and faster medical interventions.One of the unique technical and market opportunities and challenges for integrating VLSI techniques into biomedical sensor design is outlined. Engineers have a complex mess of requirements that while biocompatible, suitable for implantation, and reliable also want to optimize power consumption. Design and test considerations of VLSI based smart sensor, and direction in which novel and important areas are pointed out, are discussed in this article.
