TL;DR: In this article, a wireless capacitive pressure sensor based on LTCC (low temperature co-fired ceramic) technology is demonstrated and discussed, where the design, fabrication, and measurement of the sensor is demonstrated.

TL;DR: A temperature-compensated Fabry-Perot (FP) interferometric gas refractive index (RI) sensor, fabricated by inserting a singlemode fiber (SMF) and a hollow silica tube (HST) with an inner diameter of 5μm, from opposite ends, into a silica casing, is described and experimentally demonstrated for high-temperature application.

TL;DR: A diaphragm-free fiber-optic Fabry-Perot interferometric gas pressure sensor is designed and experimentally verified to improve the accuracy of the pressure sensor in high temperature environments and has less than 1.5% non-linearity at different temperatures by using temperature decoupling method.

TL;DR: A fiber-optic Fabry-Perot high-temperature pressure sensor based on sapphire direct bonding is proposed and experimentally demonstrated, demonstrating the sensing capabilities for pressures from 20 kPa to 700 k Pa up to 800°C.

TL;DR: The characterization in high-temperature and pressure environments successfully demonstrated sensing capabilities for pressure from 1 to 5 bar up to 600 °C, limited by the sensor test setup.
