Fluid delivery system for a microfluidic device using alternating pressure waveforms

摘要

A microfluidic fluid delivery system includes a microfluidic chip having a fluid input. A fluid reservoir is coupled to the fluid input. A gas delivery system has a gas pressure source and a variable amplitude function generator generating an alternating signal. A valve is coupled to the function generator and the gas pressure source. The valve controls the gas pressure pulse in response to said alternating signal. The gas pressure pulse displaces fluid from the fluid reservoir into the fluid input.
