“…Expanding on these advancements, Liu et al have designed a conductive and elastic sponge-based triboelectric nanogenerator (ES-TENG) that employs conductive polymers such as polyaniline (PANI) for harvesting random mechanical energy and ammonia sensing [ 44 ]. By growing PANI nanowires on the sponge’s surface ( Figure 4 b), the researchers developed a conductive elastic sponge that can harvest kinetic energy from irregular motion with various amplitudes and directions.…”

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.

We have fabricated multifunctional conductive fabrics composed of polypyrrole/BaTiO3/poly(acrylonitrile‐co‐methylacrylate) (PPy/BaTiO3/P(AN‐co‐MA)(PBA) utilizing a simple process including dip coating and in situ chemical polymerization of pyrrole, which oxidized both ammonium persulfate (APS) and ammonium persulfate + iron (III) chloride (APS + FeCl3) for flexible and wearable textile applications. The influence of the oxidant nature, PPy content, and BaTiO3 on the surface structures, electrochemical, and semiconducting characteristics of the fabrics was examined using scanning electrochemical microscopy (SEM), electrochemical impedance spectroscopy (EIS), and the Mott–Schottky (M–S) studies. The study revealed that the size of the polymer nanostructures on fabric has an impact on the electrochemical impedance properties. Specifically, a decrease in diameter (when FeCl3 + APS is used) or the formation of more compact swelling surface structures (when only APS is used) is associated with changes in the conductivity of the coated fabric. Based on the EIS tests, the composite coating (S0.1, S0.2, and S0.3) with FeCl3 has a higher electrical conductivity compared to the coating with APS (PBA). The M–S tests indicate that the semiconducting characteristics of coated fabrics are dependent upon the kind of oxidant, the amount of PPy, and the presence of BaTiO3.
