[Energy, Environment, and Sustainability] Sensors for Automotive and Aerospace Applications || Sensors Used in Flying: A Comprehensive Study
摘要： The aerospace industry is an ever-growing area where the possibility to explore and achieve next-generation technology has always been a challenge. Passenger safety with power conservation has always been areas of great interest in the global aviation sector. The induction of MEMS (micro-electro-mechanical systems) and other micro- and nanotechnologies have revolutionized the area of sensors. It has helped in drastic improvements in the performance characteristics of the systems such as sensitivity, stability, service life, etc., while reducing the overall size, weight, and power requirements. These systems are now being used aboard aircraft for various speci?c applications such as autopilot systems, navigation systems, etc., which were traditionally controlled manually using mechanical and electrical systems. This chapter aims at discussing traditional ?ight instruments and the recent advancements that have occurred due to use of MEMS. Also, we have discussed AVS (air vehicle systems) which are miniature forms of aircraft used for several speci?c purposes including military operations. The requirement for these vehicles in miniaturized navigation, power and communication systems can only be achieved using MEMS and other micro- and nanotechnologies.

[IEEE 2019 IEEE International Ultrasonics Symposium (IUS) - Glasgow, United Kingdom (2019.10.6-2019.10.9)] 2019 IEEE International Ultrasonics Symposium (IUS) - PMUT-Enabled Underwater Acoustic Source Localization System
摘要： The present work presents the novel application of Piezoelectric Micromachined Ultrasonic Transducer (PMUT) arrays in an Underwater Acoustic Source Localization System. Based on the difference in the time of arrival of ultrasonic bursts originating from an acoustic beacon, the system is capable of determining the direction to the source with no theoretical limitation on the angular range. A cross correlation technique is used to estimate the time of arrival difference between the received signals. Experiments are performed with the prototype submerged in liquid in a tank for arbitrary positions of a beacon, showing large potential for application of the system in a miniaturized, integrated platform for underwater source localization.
