Encapsulated tunable electromechanical oscillators are a milestone on the road to smart dust sensor nodes. To foster the advent of ultrahigh system sensitivity thanks to novel technologies, a computationally light analytical and semi-empirical model for carbon nanotube resonator dynamics, electromechanical and piezoresistive properties is presented. This model is the breeding ground for the subsequent design and integration of a phase locked loop and feedback circuitry, which form an adaptive closed-loop oscillator for actuation, detection and sustainment of the nanotube’s motion. Closed-loop operation and tube stretching make the system Widely universal and invariant to spreads in nanotube characteristics.
