Abstract

A flexible diaphragm or membrane for an energy conversion device and an associated energy conversion device comprising the diaphragm or membrane, the diaphragm or membrane being configured to be located between a first fluid and a second fluid and being movable in response to variations in at least one of the first and second fluids to permit energy transfer between said fluids; wherein the diaphragm or membrane includes at least one fabric or woven material. Optionally, the diaphragm is shaped so as to have a non-planar cross section in a neutral, rest or unpressurised state and/or as a multilayer diaphragm.
