Wireless Temperature Sensor Having No Electrical Connections

This technology is a new sensor made up of dielectric materials tuned to accurately measure a variable and wide range of temperatures. The sensor is wireless and is powered by an external magnetic field. As the temperature changes, the dielectric material changes its signature magnetic response and the change is detected by a magnetic field response sensor. Applications for this technology are temperature sensors for non-conductive surfaces where the conditions or operations require a robust and wireless sensor. NASA Langley Research Center has developed a robust, wireless temperature sensor that does not require an electrical connection. The temperature sensor is built on NASA's SansEC sensor platform, which takes advantage of measuring dielectric changes. The temperature sensor is damage tolerant, wireless, flexible, precise, and inexpensive. One promising application is for tire temperature sensors.
