Abstract

A method of making a pressure sensor to be positioned in fluidic connection with a fluid passageway of a housing of an implantable fluid operated device includes: providing a flexible metal diaphragm to a metal housing of the pressure sensor, where the metal housing defines an interior cavity of the metal housing; and attaching the flexible metal diaphragm to the metal housing. The flexible metal diaphragm has a first portion that is unattached to the metal housing and that, when positioned in fluidic connection with the fluid passageway of the housing of the implantable fluid operated device, is configured to move inward and outward with respect to the interior cavity in response to a fluid pressure in the fluid passageway. The first portion of the flexible metal diaphragm has a thickness of less than 40 μm, and characteristic metal grain sizes of the first portion are smaller than 10 μm.
