Low frequency energy harvesting platform for mobiles devices and sensors

压电能量收集器在各种生物医学、工业、军事和消费能量收集应用中越来越受欢迎。根据IDTechEx的一项市场研究，能源收集在2010年代表了一个新兴的7亿美元市场，到2021年有可能增长到44亿美元。已经有几次尝试为这个市场生产“最佳”压电振动驱动的能量采集器系统，但是很少有标准化的设计可以为特定的消费者应用高度定制。我们的团队最近实现了一个压电能量采集器的概念验证原型，产生13-25 μ W，工作驱动带宽为120-1000 Hz。I2I“I”阶段的目标是开发一个即插即用的压电能量低频采集器原型，以满足现有市场对消费电子产品延长电池寿命的需求。这将通过进一步优化当前的能量采集器设计来实现，使用更灵活的结构材料，改进集成和封装方案，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 μ W。在成功完成I2I“I”阶段后，下一步是与具体的商业化计划和合作伙伴一起申请I2I“II”阶段。

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.
