Abstract:Microdroplet dispensing has numerous applications in biotechnology, microelectronic packaging and microassembly. The rapid developments of these fields tend to demand smaller and smaller microdroplets. In order to achieve single picoliter-volume droplets, a piezoelectric micro-dispensing system is developed in this paper. The factors affecting the droplet volume is first investigated theoretically. Then the coupled multi-physics micro-dispensing model has been established. Based on this model, various paramete… Show more
