- Abstract
- This research program relates to feedback and control of micro-electromechanical system (MEMS) components, which may include reaction chambers, pumps, valves mixers, heaters, diffusers, nozzles, channels, fluidic interconnections and others that may be integrated in a microfluidic system and applied to medical and chemical diagnostic devices, and any devices requiring liquid-or gas-filled chambers for operation. For the purpose of this study, a micropump constructed from no-moving parts (NMP) valves, driven by a piezoelectric element membrane and bonded to a flexible diaphragm is characterized by a Laser Interferometer. In order to predict the pump's performance, a non-contact displacement measurement fibre optic interferometer is used which, when applied, dynamically characterises the pump's open loop parameters. It is intended that the steady-state parameters be mapped into the closed-loop control elements, based on continuous measurement and adaptive compensation so that the pump performance criteria are always satisfied.
