Piezoelectric and triboelectric nanogenerators (P-TENGs) have emerged as promising technologies for converting mechanical energy into electrical energy, with potential applications in self-powered wearable and environmental monitoring devices. Modular design in P-TENGs, characterized by the flexible assembly and customization of device components, enables the development of sustainable and versatile chemical sensors. In this review, we focus on the role of modularity in P-TENG-based chemical sensing, discussing how it enhances design flexibility, sensing versatility, scalability, and integration with other technologies. We explore the various strategies for functionalizing P-TENGs with specific recognition elements, facilitating selective and sensitive detection of target chemicals such as gases, biochemicals, or biomolecules. Furthermore, we examine the integration of modular P-TENGs with energy storage devices, signal conditioning circuits, and wireless communication modules, highlighting the potential for creating advanced, self-powered sensing systems. Finally, we address the challenges and future directions in the development of modular P-TENG-based chemical sensors (PCS and TCS), emphasizing the importance of improving selectivity, stability, and reproducibility for practical applications.

This study investigates the properties of tin oxide coatings employed in biomedical applications. The films were deposited on a clean glass substrate, preheated at 450 °C, applying the spray pyrolysis technique as the latter produces crystallized thin films without the need for further heat treatment. X‐ray diffraction analysis showed that tin oxide films had a tetragonal structure characterized by a preferential orientation (111). The measurements of reflectance and transmittance revealed a wide optical band gap of 4.0 eV. Nanoindentation tests showed that the tin oxide coating, with a hardness of 5.9 GPa and a Young's modulus of 78 GPa, exhibited elastic‐plastic behavior. In addition, tribological tests indicated that tin oxide coating had a very low coefficient of friction (μ=0.06), high wear resistance (wear rate 2.10−5 mm3 N−1 m−1) and good adhesion to the substrate (critical adhesion load of 5.55 N). It was also noticed that tin oxide thin films had antibacterial activity due to their nanocrystalline impurities. These properties make tin oxide perfectly acceptable for biomedical applications.

This work delves into the preparation of ATO thin films and their characterization, fabrication, and calibration of a NO2 gas sensor, as well as the development of the packaged sensor. ATO thin films were prepared by e-beam evaporation using green synthesized ATO nanomaterials on different substrates and annealed at 500 and 600 °C for one hour. The structural and morphological properties of the developed thin films were studied using scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray diffraction (XRD) techniques. An orthorhombic SnO2 crystal structure was recognized through XRD analysis. The granular-shaped nanoparticles were revealed through SEM and TEM images. The films annealed at 600 °C exhibited improved crystallinity. ATO films prepared on normal 5 µm interdigitated electrodes (IDEs) and annealed at 600 °C exhibited a response of 10.31 ± 0.25 with an optimum temperature of 200 °C for a 4.8 ppm NO2 gas concentration. The packaged NO2 gas sensor developed using IDEs with a microheater demonstrated an improved response of 16.20 ± 0.25 for 4.8 ppm of NO2 gas.
