Passive Wireless Sensor Applications for NASA’s Extreme Aeronautical Environments

NASA aeronautical programs require rigorous ground and flight testing. Many of the testing environments can be extremely harsh. These environments include cryogenic temperatures and high temperatures (>1500 °C). Temperature, pressure, vibration, ionizing radiation, and chemical exposure may all be a part of the harsh environment found in testing. This paper presents a survey of research opportunities for universities and industry to develop new wireless sensors that address anticipated structural health monitoring and testing needs for aeronautical vehicles. Potential applications of passive wireless sensors for ground testing and high-altitude aircraft operations are presented. Some of the challenges and issues of the technology are also presented.
