Improving Electrical Performance and Lifespan of Liquid‐Based Triboelectric Nanogenerator via Charge‐Inducing Structure

Advanced Functional Materials, Год журнала: 2025, Номер unknown

Опубликована: Май 8, 2025

Abstract Among triboelectric nanogenerators (TENGs), liquid‐based TENGs (L‐TENGs) have attracted attention owing to their advantage of using abundant water resources as an energy source. However, electrical performance is lower than that solid–solid (S–S) contact because relatively low charge density. In addition, the ions dissolved in neutralize surface polymer, reducing long‐term stability L‐TENGs. To address this problem, study developed a new strategy not only enhances but also durability L‐TENG. A simple charge‐inducing structure (CIS) designed provide strong reservoir via S‐S contact. Hereby, output during liquid‐solid increased from 38.8 122.7 V OC and 79 253 µA I CC . Moreover, overcomes limitation L‐TENG, which significantly decreases due influence existing enables extension lifespan. Based on structural design, portable aqua ball exercise device with usability presented application for visualizing movements real‐time. Consequently, enhancing through inertia CIS presents commercializing

Eng—Advances in Engineering, Год журнала: 2024, Номер 5(2), С. 958 - 966

Опубликована: Май 23, 2024

In this manuscript, we present a novel approach for integrating Triboelectric Nanogenerators (TENGs) into signature stamps, termed Stamp TENG (S-TENG). We have modified commercially available stamp holder to integrate triboelectric layers multiple applications like effective energy harvesting, sensing, and embedded electronics data prediction. S-TENG has been further explored in remote monitoring systems elderly individuals gathering real-time statistics regarding persons or events at specific locations. The is fabricated using FEP Al as functional layers. It demonstrates an output voltage of 310 V, current 165 μA, power density 14.8 W/m2. simplicity the S-TENG’s design noteworthy. Its ability generate through simple, repetitive stamping actions, which anyone can perform without specialized training, stands out key feature. device also designed ease use, being handheld user-friendly. flexible adaptable structure ensures that with varying physical capabilities comfortably operate it. An impressive capability its illuminate 320 LEDs each press momentarily. Furthermore, management circuits, small electronic gadgets such digital watches thermometers few seconds. addition, when integrated electronics, shows great potential prediction various practical applications.
