Abstract
A microfluidic device includes a chamber substrate, a cover substrate, a flexible membrane, and a punch unit. The chamber substrate includes a fluid chamber configured to receive a fluid and having a fluid chamber opening. The cover substrate includes a punch opening lying opposite the fluid chamber opening. The flexible membrane is positioned between the chamber substrate and the cover substrate, and spans the punch opening and the fluid chamber opening. The punch unit is configured to move into the fluid chamber through the punch opening in order to deflect the flexible membrane into the fluid chamber so as to enable the fluid to flow out of the fluid chamber when fluid is received in the fluid chamber.
