| Abstract: | Humidity sensors are omnipresent. Thus, significant efforts have been undertaken to advance their performance, for example, to have a fast detection time, negligible hysteresis, and excellent stability. Despite numerous active research endeavors, establishing a sensor that excels in all these key performances is still challenging. Here, we address this challenge by designing a capacitive-based humidity sensor employing porous LaFeO 3 perovskite. Integrating Ti into the perovskite using a sol-gel method, i.e. , LaFe 0. 925 Ti 0. 075 O 3 , results in a 400% increase in specific surface area achieved through pore formation, translating to a 2094% response parameter. Furthermore, due to the rapid equilibrium between adsorption and desorption processes, the sensor achieves ultrafast 4.4 s response time and 1.4 s recovery time, with <1% hysteresis and excellent stability over 28 days, when assessed at 300 K. Our work significantly advances current humidity sensor performance and, in a broader context, emphasizes the efficacy of porous (perovskite) materials for high performance gas detection. [Display omitted] • Incorporating Ti into LaFeO 3 introduces a tunable porosity and surface area in the perovskite. • The porous LaFe 0.925 Ti 0.075 O 3 exhibits ultrafast response/recovery times and negligible hysteresis. • This metrics puts the sensor among the highest-performing sensors in the literature. • The humidity sensing mechanisms is also explained though impedance measurement.
