This Small Business Innovation Research Phase I research project is to develop, fabricate, and characterize a new type of cost effective high performance vibration energy harvester. The use of piezoelectric benders for vibration energy harvesters has been limited due to their low energy output, high vibrational frequency requirement, and narrow frequency bandwidth. Several configurations of these energy harvesters will be fabricated that are predicted to offer up to 1.45 times higher voltage and up to 9.6 times higher current output capability over conventional monolithic and composite energy harvesters. In addition, these new harvesters offer up to 5 times lower resonance frequency and up to 10 times wider bandwidth. The proposed harvesters are projected to satisfy the powering requirements for ubiquitously deployed transportation and industrial sensor networks and mobile electronics, eliminating the need for battery recharging, replacement, and disposal. For wireless sensor networks, the proposed energy harvester will eliminate power consumption from the mains power, data cable and power cable installation and maintenance, and battery cost, replacement, and disposal. In addition, sensor data can be used to facilitate structural health monitoring and condition based maintenance of transportation infrastructure, power generation structures, and air, water, and ground transportation vehicles, which can result in multi-billion dollar savings by avoiding catastrophic failures, eliminating unnecessary scheduled maintenance, and reducing maintenance costs.

该小型企业创新研究第一阶段研究项目旨在开发、制造和表征一种新型的高性价比振动能量收集器。由于压电式弯曲器输出能量低、振动频率要求高、频带窄等原因，其在振动能量收集机中的应用受到限制。这些能量收集器的几种配置将被制造出来，预计将提供比传统单片和复合能量收集器高1.45倍的电压和9.6倍的电流输出能力。此外，这些新的收割机提供高达5倍的低共振频率和高达10倍的带宽。拟议的收割机预计将满足无处不在的交通运输、工业传感器网络和移动电子设备的电力需求，消除对电池充电、更换和处置的需要。对于无线传感器网络，拟议的能量收集器将消除主电源、数据线和电源线安装和维护的电力消耗，以及电池成本、更换和处置。此外，传感器数据可用于促进交通基础设施、发电结构以及空中、水和地面交通工具的结构健康监控和基于状态的维护，从而通过避免灾难性故障、消除不必要的定期维护和降低维护成本来节省数十亿美元。
