Design and development of an implantable circuit for adjusting required pressure inside of respiratory system

Abstract

This research has the objective to design an electrical circuit model which can compute the respiratory process. This analysis of the proposed electrical circuit model has been done in linear, non-linear, and hardware experimental processes. This work presents the electrical model realization of the respiratory system along with the introduction of a state space model under the nonlinear control domain to realize the same. Through dead and saturation zone nonlinearity, the output response of this model has been restored and its polar plot has been reexamined to determine the intersection of this characterizing function. The simulation's outcome suggests that the system is stable, based on the idea of a limit cycle in a nonlinear domain. The ExpEYES-17 development kit was used to implement the suggested circuit as proposed hardware implantable model and justified it as a reliable system. Various achieved output shows that within the lung frequency range 0.25 Hz–5 Hz, the generated output pressure is within the range of 25 to 33 Pa which resembles pressure of human lung.
