Triboelectric nanogenerators (TENGs) have revolutionized energy harvesting and active sensing, holding tremendous potential in personalized healthcare, sustainable diagnoses, and green energy applications. In these scenarios, conductive polymers play a vital role in enhancing the performance of both TENG and TENG-based biosensors, enabling the development of flexible, wearable, and highly sensitive diagnostic devices. This review summarizes the impact of conductive polymers on TENG-based sensors, focusing on their contributions to triboelectric properties, sensitivity, detection limits, and wearability. We discuss various strategies for incorporating conductive polymers into TENG-based biosensors, promoting the creation of innovative and customizable devices tailored for specific healthcare applications. Additionally, we consider the potential of integrating TENG-based sensors with energy storage devices, signal conditioning circuits, and wireless communication modules, ultimately leading to the development of advanced, self-powered diagnostic systems. Finally, we outline the challenges and future directions in developing TENGs that integrate conducting polymers for personalized healthcare, emphasizing the need to improve biocompatibility, stability, and device integration for practical applications.

“…12 Polyaniline (PAni) is a conductive polymer that can be easily synthesized through the oxidation of the monomer (Ani) in aqueous and non-aqueous solutions in the presence of (poly)electrolytes. 21 This makes it a promising candidate for commercial applications, as it is low-cost and highly stable. PAni's properties vary based on its oxidation state (Fig.…”

The electrosynthesis of polyaniline (PAni) and cashew gum (CG) composite was successfully performed by electrochemical methods (potential scanning and constant potential) in terms of pH, aniline (Ani), and polyelectrolyte concentrations. Our aim was to investigate the performance of a polyaniline-based ammonia sensor under different concentrations of ammonium gas, evidencing a color change from green to blue as in the presence of gas in a sensitive and reversible process. Films grown by cyclic voltammetry and chronoamperometry showed a cauliflower-like morphology, and a visual analysis detected a limit of 0.015 and 0.010 mol/L, respectively. The sensor demonstrated a fast response time of 20 seconds, a low detection limit, with a short regeneration time of less than 1 minute at room temperature. This polyaniline-based sensor is shown to be a portable, sensitive, dimensionally flexible, and cost-effective alternative for food packaging and other devices. The findings of this study contribute to the development of advanced ammonia detection technology.
