Harsh Environment Special Sensors: From Materials to Electrical Readout
Deadline for manuscript submissions: closed (31 December 2020) | Viewed by 3863
The development of advanced sensors and actuators capable of operating in harsh environmental conditions, which include but are not limited to high temperatures, high radiation, high shock, and chemically corrosive environments, has experienced significant expansion in recent years. There is an abundance of applications (combustion optimization and emission control in automotives; geothermal, oil and gas exploration; industrial gas turbines and furnaces; nuclear industry; carbon capture and sequestration; smart infrastructures; space exploration; etc.) which would benefit from the deployment of sensors able to operate in harsh environment conditions. The merits of these advanced sensors include integration into smart structures and components, improved robustness, enriched functionality, enhanced intelligence, and unprecedented performance.
In the last decade, both industry and academia have put a lot of effort into the development of new materials that are able to overcome the limitations in silicon-based microelectronics and nanoelectronics, especially at temperatures above 150°C.
Silicon-on-insulator devices, although not too different from bulk silicon-based sensors, from a chemical and mechanical perspective, provide extended working temperature ranges (up to 300 °C) and radiation hardness. Silicon carbide (SiC), gallium nitride (GaN), aluminium nitride (AlN), and diamond are certainly also extremely attractive in terms of intrinsic properties.
This new Special Issue on Harsh Environment Special Sensors: From Materials to Electrical Readout invites researchers to contribute with reviews and original articles that delve into further performance improvements of advanced sensors for severe conditions. Particular focus is placed on smart parts (innovative sensors, smart interfaces, and readout circuits) to address the monitoring needs within extreme environment conditions, such as high temperature, high pressure, corrosive/erosive atmosphere, and large strain/stress.
Practical sensor monitoring probes usually consist of a sensing element and processing circuitry, packaged in a metal or ceramic casing. Dedicated read-out circuits convert the sensor output signal to industrial standard requirements. Automation of the read-out calibration process, lowering probe power consummation, and improving sensitivity are also key contributions, suitable for the Special Issue. Both experimental and theoretical/simulated results will be taken into account.
