Electrically addressable, liquid release well array for a hand-held,scent-dispense system

摘要

A microelectromechanical system microfabricated prototype is presented that stores and dispenses liquid materials, using digitally activatednburst pressure to release fluid within an array of microwells. Electrically addressable microheaters are used to thermally crack a plastic mem-nbrane above each well, releasing pressurised scented material. This low-cost, disposable device allows users to control the selection and releasenof a variety of stored fluids.
