项目摘要

Piezoelectric energy harvesters are growing more popular for a variety of biomedical, industrial, military and consumer energy harvesting applications. According to a market study by IDTechEx, energy harvesting represented an emerging $0.7B market in 2010, with the potential to grow to $4.4B by 2021. There have been several attempts to produce an "optimum" piezoelectric vibration-driven energy harvester systems for this market, but few standardized designs exist that are highly customizable for a specific consumer application. Our team has recently achieved a prototype for a proof of concept of a piezoelectric energy harvester producing 13-25 µW, with operating actuation bandwidth of 120-1000 Hz. The goal of this I2I Phase "I" is to develop a plug-and-play prototype of a piezoelectric energy low frequency harvester to satisfy the existing market need of extended battery life for consumer electronics. This will be accomplished through further optimization of the current energy harvester design, using a more flexible structural material and improving integration and packaging schemes to increase the power generation of the energy harvester to 75-125 µW within the lower 30-300 Hz operational frequency bandwidth. On the successful completion of this I2I Phase "I", the next step is to apply for I2I Phase "II" with a specific commercialization plan and partner.

压电能量收集器在各种生物医学、工业、军事和消费者能量收集应用中越来越受欢迎，根据 IDTechEx 的一项市场研究，能量收集在 2010 年代表着一个新兴的 $0.7B 市场，到 2010 年有可能增长到 $4.4B。 2021 年。已经多次尝试为该市场生产“最佳”压电振动驱动能量采集系统，但很少有可针对特定消费者应用进行高度定制的标准化设计。我们的团队最近实现了压电能量采集器的概念验证原型，其功率为 13-25 µW，工作驱动带宽为 120-1000 Hz。该 I2I 阶段“I”的目标是开发一种即插即用的设备。开发压电能量低频收集器原型，以满足消费电子产品延长电池寿命的现有市场需求，这将通过进一步优化当前能量收集器设计、使用更灵活的结构材料和改进来实现。集成和封装方案可在较低的 30-300 Hz 工作频率带宽内将能量采集器的发电量提高到 75-125 µW 在成功完成 I2I 阶段“I”后，下一步是申请 I2I 阶段。 “II”有具体的商业化计划和合作伙伴。
