Recent studies on the humidity sensor: a mini review

Official URL: https://dx.doi.org/10.1021/acsaelm.2c00721

For the time being, a number of humidity measurement instruments made of a variety of different materials and operating on a number of different principles are accessible. There are numerous ways that may be utilized to categorize them. I begin by discussing the most commonly used designs for flexible humidity sensors. Following that, the section on humidity-sensitive materials, the sensing mechanism, the major properties of humidity sensors, and the influence of temperature on humidity sensors are discussed. The study concludes with a review of current research in this area, as well as the challenges that exist. The majority of the studies included in this review were published between 2020 and 2022. These remarks are expected to serve as an overview to humidity measurement for researchers and graduate students who are new to the field or who are already working in it and would like to learn more about the issue.
