A low-profile, axial-flow, single-blade piezoelectric fan is provided. The fan is in the form of a piezoelectric fan assembly (300) which contains a housing (302) defining an axial flow-through internal cavity. Inside the housing (302) is a single fan blade (314) which is attached at only one end to the housing (302). A piezoelectric element (318) is fixedly mounted to the single fan blade (314) and causes the single fan blade (314) to deflect when the piezoelectric element (318) is activated. This piezoelectric fan assembly (300) may be used to cool electronic components in applications where low-power and low-volume fanning is desired.
