High-temperature multiferroic magnetoelectric sensors
Applied Physics Letters, 2022Magnetoelectric (ME) sensors are an important tool to detect weak magnetic fields in the industry; however, to date, there are no high-quality ME sensors available for high-temperature environments such as engines, deep underground, and outer space. Here, a 0.364BiScO3–0.636PbTiO3 piezoelectric ceramic and Terfenol-D alloy with a Curie temperature of ...

High-speed fiber-optic temperature sensor
Optics Letters, 1991The temporal response of a fiber-optic Fabry-Perot-type interferometer, formed by cleaving the ends of a length of highly birefringent (Hi-Bi) fiber, to high-frequency heat pulses is investigated both theoretically and experimentally. The heat pulses are produced by amplitude modulating the output of an argon laser with a variable frequency Bragg cell.

Evaluation of high temperature pressure sensors
Review of Scientific Instruments, 2011It is becoming more important to measure the pressure in high temperature environments in many industrial fields. However, there is no appropriate evaluation system and compensation method for high temperature pressure sensors since most pressure standards have been established at room temperature.

Sourceless optical fiber high temperature sensor
Optics Letters, 2015A sourceless sapphire fiber extrinsic Fabry-Perot interferometer for ultrahigh temperature sensing is developed. A sapphire wafer is mounted on the tip of a sapphire fiber as the Fabry-Perot cavity. The interference signal is generated by the thermal radiation that transmits through the wafer and is guided to a spectrometer by a sapphire and then a ...

High-temperature Bragg grating waveguide sensor
Proceedings International Conference on MEMS, NANO and Smart Systems, 2004Design and analyses of a periodic dielectric Bragg grating waveguide temperatures reported in this work. The sensor is capable to measure temperatures ranging from room temperature to over 1200/spl deg/C. By using this sensor combined with a wavelength shifting detector and radiation detection schemes, a wide range thermometer can be built. Temperature

High-temperature processes in the field of, e.g., energy conversion or chemical technologies require sophisticated process monitoring and control to ensure high-efficiency, low pollutant emissions, and safe operation. These objectives can only be achieved by in-situ control of the processes.

High-temperature langasite SAW oxygen sensor
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2011High-temperature langasite SAW oxygen sensors using sputtered ZnO as a resistive gas-sensing layer were fabricated and tested. Sensitivity to oxygen gas was observed between 500°C to 700°C, with a sensitivity peak at about 625°C, consistent with the theoretical predictions of the acoustoelectric effect.

Nanoscale optical high-temperature sensor
2017 IEEE International Conference on Microwaves, Antennas, Communications and Electronic Systems (COMCAS), 2017All-dielectric nanoparticle possesses strong inherent Raman response due to allowed optical phonon modes. We show that such (crystalline silicon) nanoparticle with a magnetic quadrupolar Mie resonance converts light to heat with simultaneous Raman thermometry up to 900 K. The advantage of using crystalline silicon is the simplicity of local temperature
