本文报道了六个动态结构的仿真分析，就其腕戴式振动能量收集能力。这项工作的方法的问题，最大限度地提高能量收集潜力的手腕，考虑多个机械子结构，旋转和线性运动为基础的架构进行检查。数学模型的开发和实验证实。一个优化程序被应用到所提出的架构，以最大限度地提高平均功率输出，并允许比较。在结构中添加线性弹簧元件有可能提高功率输出;例如，在旋转结构的情况下，在真实的行走激励下估计功率输出提高211%。分析得出结论，当使用真实的行走数据作为模拟的输入时，弹簧旋转采集器架构的性能优于弹簧线性架构66%。
This paper reports the simulation-based analysis of six dynamical structures with respect to their wrist-worn vibration energy harvesting capability. This work approaches the problem of maximizing energy harvesting potential at the wrist by considering multiple mechanical substructures; rotational and linear motion-based architectures are examined. Mathematical models are developed and experimentally corroborated. An optimization routine is applied to the proposed architectures to maximize average power output and allow for comparison. The addition of a linear spring element to the structures has the potential to improve power output; for example, in the case of rotational structures, a 211% improvement in power output was estimated under real walking excitation. The analysis concludes that a sprung rotational harvester architecture outperforms a sprung linear architecture by 66% when real walking data is used as input to the simulations.
