Beschreibung
Zusammenfassung:	Disclosed herein is a flow control device. The flow control device comprises a sheet made from a shape memory alloy. The flow control device also comprises at least one slit through the sheet. At least the one slit defines at least one flap in the sheet. The flow control device further comprises at least one electrically-resistive trace printed on the sheet at least one of on or adjacent at least the one flap. Upon receipt of an electrical current, at least the one electrically-resistive trace configured to generate heat for deforming at least the one flap relative to the sheet and opening an aperture formed in the sheet.
