Abstract
A device for moving air comprising a piezoelectric element attached to a planar body. The planar body is configured to oscillate at a movable end generating an airflow in response to applying alternating electric current to said piezoelectric element. The device further comprises a partial cavity defined by a base plate, a first wall and a second wall which surrounds the movable end of the planar body. The base plate further comprises an opening located proximate to said movable end of the planar body. In operation the air flow generated by the planar body is forced out of the device through the opening.
