Abstract
Nano/microelectromechanical system (N/MEMS) have garnered significant global attention for their transformative applications across various cutting-edge fields, including wearable devices, 5G service, collecting power, and space travel. These systems face challenges when exposed to excessive forces and leading to pull-in instability that can undermine a reliable performance. Therefore, it is essential to quickly and precisely comprehend the periodic motion of the system to minimize the possibility of pull-in instability and maintain consistent operation. This article explores the application of the homotopy transformation scheme (HTS) for forecasting dynamic behavior of N/MEMS. The most advantage of HTS is its ability to deliver results without relying on hypotheses, assumptions, or constraints on variables. To illustrate its effectiveness, we use a generalized N/MEMS oscillator system, presenting an accurate analysis of analytic solution. Specifically, we focus on a microstructure of nanobeam-based system actuated by van der Waals (vdW) forces to highlight its periodic characteristics. The results reveal that HTS provides a robust comparison and excellent agreement with the exact solution, underscoring its reliability and precision.
