Abstract

To foster the development of highly sensitive carbon nanotube nanoelectromechanical sensor systems, a computationally light analytical and semi-empirical model for the latter´s dynamics, electromechanical and piezoresistive properties is presented. This model is the breeding ground for the subsequent design and implementation of a phase locked loop and feedback circuitry, which form an adaptive closed-loop oscillator for actuation, detection and sustainment of the sensor´s motion.
