项目摘要

The objective of this research is to develop a prototype vibration energy harvesting device that can be used as a self-powering, miniature and fully-integrated wireless sensor network node for long-term sensing and monitoring applications. These piezoelectric-based devices, on the order of a cubic millimeter in volume, offer two orders of magnitude improvement over the state-of-the-art. The approach of this project is to merge three-dimensional numerical simulations with material property characterization experiments on both single-crystal silicon and piezoelectric thin films, in order to push both materials to their respective mechanical limits. Efforts to develop cheap, batch-fabrication compatible manufacturing processes will be undertaken simultaneously.The intellectual merit of this work is the incorporation of large, nonlinear deflection dynamics directly into the design of the micro-scale devices; this approach enables optimal voltage generation, allows effective energy harvesting at low frequencies, and obviates any design customization, mechanical trimming or resonance tuning. The broader impacts are likely to include pervasive, cheap, easy-to-deploy, reliable and sustainable sensor networks, with direct impact potential in homeland security, environmental and structural integrity monitoring, battlefield awareness, automatic border surveillance, and package tracking. The study will provide valuable opportunities for the interdisciplinary training of both undergraduate and graduate students. In collaboration with the Connecticut Pre-Engineering Program (CPEP), the PI will be participating in the high school teacher development program and classroom enrichment activities around the New Haven area, which has a significant population of socially and economically at-risk children, as well as a high concentration of traditionally underrepresented minority students.
本研究的目的是开发一种原型的振动能量采集装置,它可以作为一个自供电、小型化和全集成的无线传感器网络节点,用于长期的传感和监测应用。这些体积约为1立方毫米的基于压电的设备,比最先进的设备提供了两个数量级的改进。该项目的方法是将单晶硅和压电薄膜的三维数值模拟与材料性能表征实验相结合,以将这两种材料推向各自的力学极限。同时,将努力开发廉价的、批量制造兼容的制造工艺。这项工作的智力优势是将大的、非线性的偏转动力学直接纳入微型器件的设计中;这种方法能够实现最佳电压产生,允许在低频下有效地收集能量,并避免任何设计定制、机械微调或共振调谐。更广泛的影响可能包括无处不在、廉价、易于部署、可靠和可持续的传感器网络,对国土安全、环境和结构完整性监测、战场感知、自动边境监视和包裹跟踪具有直接影响潜力。这项研究将为本科生和研究生的跨学科培养提供宝贵的机会。在康涅狄格州工程预科项目(CPEP)的合作下,国际学生联合会将参与纽黑文地区的高中教师发展计划和课堂充实活动,该地区有大量处于社会和经济风险中的儿童,以及高度集中的传统上代表不足的少数民族学生。
