“…A customized SU-8 3005 solution is prepared from the standard, highly viscous SU-8 3050 photoresist. BTO NPs are chosen over other activating nano-filers due to their low UV patternability interference of SU-8, [17] a high piezoelectric coefficient (d 33 ) of 140-149 pm V −1 , high dielectric constant of 1200-1700, large electromechanical coupling coefficient (κ 33 ) of 0.5 and an isotropic spontaneous polarization (Further details in Table S1, Supporting Information).

“…[27][28][29][30] A combined photopatternability and piezoelectric optimization based on the % weight ratio ZnO and BTO in SU-8 has been recently reported. [17,32] However, there are vast unexplored opportunities in SU-8 based nanocomposites in terms of hybrid transduction as the triboelectric properties of SU-8 based nanocomposites have not been explored significantly. Also, the optimization of BTO/SU-8 nanocomposites as a dual transducer for energy harvesting/sensing applications is yet to be reported to the best of the author's knowledge.…”

The sustenance of the growing Internet of Things revolution requires suitable self‐powering solutions, which can be appropriately complemented by developing efficient energy harvesting systems. Typically, conventional piezoelectric thin film‐based energy harvesters are not promising due to high cost, low coverage area, and size‐frequency‐power trade‐off. Piezoelectric/triboelectric transduction driven mechanical energy harvesters (MEHs) based on nanocomposites offer better efficiency, cost‐effectiveness, and large‐scale production. Here, % weight ratio‐dependent piezoelectric/triboelectric property analysis, and optimization of Barium Titanate (BTO)/SU‐8 based photopatternable nanocomposite thin films are reported for developing highly efficient MEHs. Further, the performance of the nanocomposite is shown to be enhanced by controlled graphene nano‐platelet doping and ultraviolet (UV) exposure. Elaborate Finite Element Method (FEM) study is performed to support the experimental findings. Finally, three MEH devices are developed based on the optimally prepared variants of the nanocomposite and compared experimentally. A maximum output voltage of ≈3 V and power density of 0.65 µW cm−2 are obtained at 0.75 g and at the resonance frequency of 38 Hz from the graphene doped 20% BTO/SU‐8 based harvester. The prototypes have demonstrated the potential to deliver a regulated output voltage of 3.3 V within 40 s of periodic excitation upon integration with a customized power management unit for powering low‐power electronics.

“…13,14 Among the TE materials, the Zn−Sb compounds are pretty attractive because they contain environment-friendly, nontoxic, and cheap chemical elements. 15,16 The β-Zn 4 Sb 3 crystal, as a typical Zn−Sb-based TE material, is regarded as a prospective candidate TE material in the mid-temperature range (400−700 K) due to its excellent thermoelectric performance. 17,18 β-Zn 4 Sb 3 is a p-type semiconductor material with a rhombohedral structure (space group: R3̅ c) and meets the concept of "phononglass and electron-crystal (PGEC)", 19 and it exhibits a particularly low lattice thermal conductivity (κ L ) for the complex crystal structure.…”

β-Zn 4 Sb 3 is a promising thermoelectric (TE) material, as it contains low-cost and environment-friendly elements. However, its application has long been limited due to the lower figure of merit (ZT), poor mechanical properties, and inferior thermodynamic stability. In this research, we successfully synthesized Na/Ga codoped β-Zn 4 Sb 3 with high thermoelectric performance and stability. The power factor (PF) value of the Ga-doped sample is significantly improved by optimizing carrier concentration, the maximum value of 2.28 × 10 −3 W m −1 K −2 is obtained at 690 K, and the maximum ZT reaches 1.73 at 690 K for the Zn 4.1 Sb 3 (NaCl) 7 Ga 0.12 sample. Moreover, the TG-DSC and oxidation resistance tests show that Na and Ga codoped β-Zn 4 Sb 3 possess good stability. This work provides an attractive method for improving the thermoelectric properties and stability of β-Zn 4 Sb 3 through diatomic doping.

Wearable electronic textiles (e‐textiles) have emerged as a transformative technology revolutionizing healthcare monitoring and communication by seamlessly integrating with the human body. However, their practical application has been limited by the lack of compatible and sustainable power sources. Various energy sources, including solar, thermal, mechanical, and wind, have been explored for harvesting, leading to diverse energy harvesting technologies, such as photovoltaic, thermoelectric, piezoelectric, and triboelectric systems. Notably, 2D materials have gained significant attention as attractive candidates for energy harvesting and storage in e‐textiles due to their unique properties, such as high surface‐to‐volume ratio, mechanical strength, and electrical conductivity. Textile‐based energy harvesters employing 2D materials offer promising solutions for powering next‐generation smart and wearable devices integrated into clothing. This comprehensive review explores the utilization of 2D materials in textile‐based energy harvesters, covering their preparation, fabrication, and characterization strategies. Recent advancements are highlighted, focusing on the integration of 2D materials and their practical implementations, shedding light on the performance and effectiveness of 2D‐material‐based energy harvesters in e‐textiles, and highlighting their potential as a sustainable alternative to conventional power supplies in wearable technologies.
