Resumen:

Sensors are the initial source of information for many systems. This means that, sensors are the link between a phenomenon, or process, with a system devoted to controlling a process or for a system for acquiring and processing information. In this regard, it is clear that a sensor must be capable of interacting with the desired parameter, leading to the need to develop novel transducing mechanisms. Zeolites are porous materials with a composition based on silicon and aluminum, and they possess the capacity for selective adsorption, ion-exchange capacity, and molecular sieving. This is possible since zeolites have a well-defined crystalline structure, porous cavities or regular dimensions, thermal stability, and a chemical affinity that can be tailored for specific tasks. Since zeolites can be used as adsorbents for specific chemical species, and this capacity can be adjusted after a chemical modification, zeolites can be used for the development of sensors, where the variation in the properties of zeolites can be converted into an electrical signal. To date, there are diverse approaches to the development of sensors based on zeolites. In this chapter, the basics of the development of sensors with zeolites are discussed, and their applications are presented. © 2022 Nova Science Publishers, Inc..
