Dynamic Modeling and Control of a Micro-needle Integrated Piezoelectric Micro-pump for Diabetes Care

This paper proposes a micro-needle integrated piezoelectric micro-pump for subcutaneous injection of insulin for diabetes care. The micro-needle integrated micro-pump is part of an insulin monitoring and delivery system, which consists of a piezoelectric micro-pump, multiple silicon micro-needles, insulin reservoir, wireless telemetry and remote control components. The piezoelectric micro-pump is remotely controlled through wireless telemetry. A nonlinear dynamic model is presented to interpret/predict dynamics of the integrated micro-device, and used to design feedback control system for the insulin delivery. We propose a novel nonlinear dynamic model for the micro-needle integrated piezoelectric micro-pump and feedback control system design.
