This research aims to use energy harvested from conductive materials to power microelectronic components. The proposed method involves using vibration-based energy harvesting to increase the natural vibration frequency, reduce the need for battery replacement, and minimise chemical waste. Piezoelectric transduction, known for its high-power density and ease of application, has garnered significant attention. Additionally, graphene, a non-piezoelectric material, exhibits good piezoelectric properties. The research explores a novel method of printing graphene material using 3D printing, specifically Direct Ink Writing (DIW) and fused deposition modelling (FDM). Both simulation and experimental techniques were used to analyse energy harvesting. The experimental technique involved using the cantilever beam-based vibration energy harvesting method. The results showed that the DIW-derived 3D-printed prototype achieved a peak power output of 12.2 µW, surpassing the 6.4 µW output of the FDM-derived 3D-printed prototype. Furthermore, the simulation using COMSOL Multiphysics yielded a harvested output of 0.69 µV.
本研究旨在利用从导电材料中收集的能量为微电子元件供电。所提出的方法包括使用基于振动的能量收集来提高固有振动频率、减少电池更换需求并将化学废物降至最低。压电转换因其高功率密度和易于应用而备受关注。此外,石墨烯这种非压电材料也表现出良好的压电特性。该研究探索了一种使用3D打印技术打印石墨烯材料的新方法,特别是直接墨水书写(DIW)和熔融沉积建模(FDM)。同时采用了模拟和实验技术来分析能量收集情况。实验技术涉及使用基于悬臂梁的振动能量收集方法。结果表明,通过DIW技术3D打印的原型实现了12.2微瓦的峰值功率输出,超过了通过FDM技术3D打印的原型的6.4微瓦输出。此外,使用COMSOL Multiphysics进行的模拟得出的收集输出为0.69微伏。
