Simple Piezoelectric Droplet Generator



Jiann C. Yang, W. S. Chien, M D. King, William L. Grosshandler


A design for a piezoelectric on-demand droplet generator is presented. Its simple construction and ease of operation distinguish this generator from other previously reported. The droplet generator has been successfully used to produce droplets of aqueous solutions with very high dissolved salt loadings and is currently used to study droplet import and evaporation on a heated surface.
