Sicn sensors for high-temperature pressure detection
SiCN sensors offer a breakthrough in pressure detection at temperatures up to 1300°C, using a conductive ceramic material derived from reduced Graphene Oxide. This technology addresses the challenges of high-temperature environments where conventional sensors fail.
Overview
SiCN sensors represent a cutting-edge solution for pressure detection in high-temperature environments, reaching up to 1300°C. Traditional temperature and pressure measurement methods often fail at these extreme conditions, but SiCN sensors overcome these limitations using an innovative material synthesized from polymers. This material maintains its integrity at high temperatures, providing reliable pressure measurements where other sensors might falter.
Technical specifications
- Material composition: The sensors utilize a ceramic material derived from Polycarbosilane and Polisilazane, which proves stable at high temperatures.
- Conductivity enhancement: Incorporation of reduced Graphene Oxide (rGO) allows for the creation of conductive paths, enhancing the sensor's ability to measure pressure accurately at elevated temperatures.
- Fabrication method: Modified photolithography and metallic powders are used to shape the sensitive material, ensuring precision and reliability.
- Validation approach: Future validation involves indirect measurement techniques and FEA modeling to evaluate stresses and strains, ensuring the sensor's performance in real-world applications.
Technology readiness level
Currently at TRL 3, the SiCN sensors are in the experimental proof-of-concept stage. The next steps involve building prototypes based on FEA simulations and conducting lab tests to refine the design and validate performance under simulated conditions.
