Implantable mechanical pressure sensor and method of manufacturing the same

An intraocular passive pressure sensor for measuring the intraocular pressure, comprising:

• at least one micromachined flexible closed hollow body formed of a biocompatible material having first and second ends, said body being disposed on a substrate and describing at least one curve, wherein one of said ends is affixed to said substrate and the second of said ends and at least the portion of the body adjacent to said second end is allowed to move within a two-dimensional plane,
• wherein the pressure within said closed body is fixed, and wherein the arc of the at least one curve of the body is defined by the relative pressure between the internal pressure of the body and the surrounding environment, such that a change in the pressure surrounding the body causes a change in the arc of the at least one curve resulting in a measurable displacement of the second end of said body relative to the substrate, and
• wherein the displacement of the second end of said body provides a measurement of the environmental pressure surrounding the body, said displacement capable of being monitored visually.
