摘要

介绍了一种基于洛伦兹力激励的纸本机电系统(PB-EMS)。这样的系统由一个基于纸的悬臂梁组成，该梁由传统的打印纸、可打印的电子设备和标准切割工具制成。结果表明，利用洛伦兹力驱动原理研制PB-EMS是可行的。此外，还分析了驱动电流对PB-EMS动态响应的影响。当励磁电流的大小增加时，发现了一种软化效应。使用集总模型评估这种软化效果。弹簧常数作为激励电流的函数呈线性关系。此外，利用图像处理技术对系统的频率响应进行了实验研究。当激励电流为300毫安时，谐振频率的最大变化为标称频率的16.5%。因此，期望洛伦兹力激励可以应用于所提出的PB-EMS的驱动和调谐行为。

Lorentz force actuation of paper-based electromechanical systems

A paper-based electromechanical system (PB-EMS) driven by means of the Lorentz force excitation method is introduced in this work. Such a system consists of a paper-based cantilever beam that is fabricated using conventional printer paper, printable electronics, and standard cutting tools. The results show the feasibility to develop PB-EMS using the Lorentz force actuation principle. In addition, the influence of the driven current on the dynamic response of the PB-EMS is analyzed. A softening effect is identified when increasing the magnitude of the excitation current. This softening effect is evaluated using a lumped model. The spring constant as a function of the excitation current exhibits a linear relationship. Moreover, the frequency response of the system is experimentally studied by using image processing. The maximum variation of the resonance frequency is measured as 16.5% of the nominal frequency when using an excitation current of 300 mA. Thus, it is expected that the Lorentz force excitation can be applied to both drive and tune the behavior of the proposed PB-EMS.
