Wireless Temperature Sensor for High-Temperature Environments

Existing temperature sensors such as thermocouples, optical-based non-contact sensors, and piezoelectric sensors have their own advantages, but they cannot operate wirelessly. Functional electronics such as batteries, chips, and wires cannot operate at high temperatures furthering the problem. There is a need for high temperature sensors that can wirelessly transmit data to monitor dynamic systems.

FSU researchers created a wireless temperature sensor which can measure temperatures of at least 1000 °C. This novel sensor can collect measurements in harsh conditions such as high temperatures (e.g., 700 °C to 1,800 °C), elevated pressures (e.g., 200 psi to 50,000 psi), corrosive environments, and environments including radiation. The novel device is generally made up of a conductive material, a dielectric material, and a ground plane and can be manufactured in any shape. This wireless sensor has the potential to revolutionize the space industry, defense industry, and engineering.
