Pull-in Voltage Analysis of Carbon Nanotube Based Electrostatic Actuators by Using the ANSYS Software

Abstract:

This Paper presents the design and simulation of single walled carbon nanotube (SWCNT) based cantilever type electrostatic actuator using finite element analysis method (FEM). The pull-in voltage has been calculated for various chirality of the nanotube based cantilever beam actuators. The pull-in voltage are obtained for the various gap between electrode and ground of the cantilever beam through extensive simulations using ANSYS software. The results obtained shows that pull-in voltages varies from 2.5 to 13.5V with respect to nanotube chirality and gap length.
