Recent Advances in Multifunctional Sensing Technology on a Perspective of Multi-Sensor System: A Review

Due to rapid advancement in technology, recently a significant amount of work has been carried out in the field of multi-mode sensor and multifunctional sensor. A single unit of multifunctional sensor provides multiple measurements, which eventually reduces the cost of multiple sensors and makes the system compact. Though the risk of sensor failure and reliability of the multifunctional sensor is always imminent, researchers are working out different methods to make the sensor fault tolerant. Multifunctional sensors are getting widespread acceptance in a variety of fields. This paper provides a review of recent advances in multifunctional sensor technology in the perspective of a multi-sensor system. Different aspects of design and implementation of multifunctional sensor technology have been addressed in this paper. This paper can serve as a basic reading material for students and researchers pursuing research on a multifunctional sensor.
