Cell motion within a liquid suspension inside a piezoelectrically actuated,
cylindrical inkjet printhead was studied using high speed imaging and a low depth of field
setup. For each ejected droplet, a cell within the inkjet nozzle was observed to exhibit one of
three possible behaviors which are termed: cell travel, cell ejection and cell reflection. Cell
reflection is an undesirable phenomenon which may adversely affect an inkjet’s capability in
dispensing cells and a possible reason why it was previously reported that the rate of cells …
