Abstract
A method of making an implantable fluidic pump includes applying a stress to a flat metal foil to form the foil into a non-flat configuration and, while the metal foil is in in the non-flat configuration, attaching the metal foil to a flat surface of a metal base plate to form a chamber between the foil and the flat surface. Then, while the metal foil is in in the non-flat configuration and attached to the flat surface of the metal base plate, a piezoelectric element is attached to the foil, where the piezoelectric element is configured to change a distance between the foil and the flat surface of the metal base plate.

A method of making an implantable fluidic pump, the method comprising:
- applying a stress to a flat metal foil to form the foil into a non-flat configuration;
- while the metal foil is in in the non-flat configuration, attaching the metal foil to a flat surface of a metal base plate to form a chamber between the foil and the flat surface;
- and
- while the metal foil is in in the non-flat configuration and attached to the flat surface of the metal base plate, attaching a piezoelectric element to the foil, the piezoelectric element being configured to change a distance between the foil and the flat surface of the metal base plate.
A method of making an implantable fluidic pump, the method comprising:
- providing a flat metal foil to a flat surface of a metal base plate, wherein a first temperature of the metal base plate is higher than a second temperature of the flat metal foil;
- attaching a perimeter of the metal foil to the flat surface of the metal base plate while the temperature of the metal base plate is higher than the temperature of the metal foil;
- bringing the flat metal foil and the metal base plate into thermal equilibrium after the metal foil is attached to the metal base plate, wherein bringing the flat metal foil and the metal base plate into thermal equilibrium causes the base plate to contract relative to the metal foil and to form the foil into a non-flat configuration to form a chamber between the foil and the flat surface;
- and
- while the metal foil is in in the non-flat configuration and attached to the flat surface of the metal base plate, attaching a piezoelectric element to the foil, the piezoelectric element being configured to change a distance between the foil and the flat surface of the metal base plate.
