In this article we applied nTP to fabricate Au PC hybrid nano resonators on a PC substrate. When an AC voltage is applied the nano resonator can be mechanically excited when the AC frequency reaches the resonant frequency of the nano resonator. We then performed systematic parametric studies to identify the parameters that govern the resonant frequency of the nano resonators using finite element method. The quantitative results for a wide range of materials and geometries offer vital guidance to design hybrid nano resonators with a tunable resonant frequency in a range of more than three orders of magnitude . 10 KHz-100 MHz . Such nano resonators could find their potential applications in nano electromechanical devices. Fabricating hybrid nano resonators via nTP further demonstrates nTP as a potential fabrication technique to enable a low-cost and scalable roll-to-roll printing process of nanodevices. Introduction Flexible electronics is an emerging technology that will have a significant social impact through an exciting array of applications such as low-cost electronic paper printable thin-film solar cells and wearable power harnessing devices to name a few 1-7 .
