SansEC (Sans Electric Connections) Temperature Sensor and Its Applications in Tire Safety Monitoring: (R&D 100 award of 2011 Winner)

SansEC (Sans Electric Connection) sensing technology is a new fundamental technical framework of developing inexpensive wireless passive sensors. The SansEC sensor, composed of an open circuit conductive pattern, having no electrical connection, is a general sensing platform that can be applied to applications in many fields. It possesses the unique feature of being able to work after having sustained damage distinguished by the sensor, or rom any previously developed electrical devices, which make it suitable for extreme and harsh environments where other sensors would fail. The SansEC sensor has demonstrated many measurement capabilities, including: damage detection, distance measurement, high speed motion measurement (e.g. tire rotation), posture angle, temperature, chemical component detection, liquid level, material properties (conductivity and dielectric), touch/existence, deformation, and strain.

SansEC was originally developed as a method of having thermal insulation serve as a damage detection system for inflatable space structures. The researchers discovered its additional unique qualities as a new foundational technical framework of developing sensors. The simple design with only a few components makes the device easy and inexpensive to produce.

The sensor represents next generation technology for vehicle tire safety monitoring, which has a potentially large global market. By monitoring temperature, damage and rotation, the sensor can significantly improve vehicle tire safety, thereby significantly advancing vehicle safety by improving the detection of tire damage compared to conventional tire pressure monitoring systems

Dr. Chuantong Wang was named as a winner of a 2011 R&D 100 Award for work done in collaboration with researchers at NASA Langley Research Center (LaRC) in developing the “SansEC Temperature Sensor.” Dr. Wang was honored at the R&D 100 Awards Banquet on October 13, 2011, in Orlando, FL along with co-inventor Bryant D. Taylor, ATK Space Systems, and Principal Investigator, the late Dr. Stanley E. Woodard, Senior Scientist at NASA Langley Research Center. The R&D 100 Awards, widely recognized as the “Oscars of Innovation” salute the 100 most technologically significant products from around the world introduced into the marketplace over the past year. Winners of the R&D 100 Awards are selected by an independent judging panel and the editors of R&D Magazine.

NASA Aviation Safety Program—Atmospheric Environmental Safety Technologies (AEST) Project—Atmospheric Hazard Sensing & Mitigation (AHSM

Lightning strikes are a serious threat to the safety of aircraft. This is especially true for those who possess a considerable amount of composite material structures. Statistics on lightning strikes reported by aircraft pilots indicate that an aircraft is likely to receive one or two lightning strikes per year on average. Research is being conducted to develop a new method and system for aircraft protection, damage detection, and diagnosis in lightning strike events. The concept is to apply a SansEC sensor array on the surface of the aircraft as a “smart skin” layer. The research is being conducted by the Lightning Electromagnetic Effects & Mitigation (LEEM) team under the AEST project at Electromagnetics and Sensors Branch of NASA Langley Research Center.
