1. A corrugated diaphragm actuator comprising:
a chamber body comprising a plurality of walls defining a cavity,
wherein the plurality of walls comprises a first wall comprising a first corrugated diaphragm defining at least one first corrugated channel extending circumferentially about a central longitudinal axis of the corrugated diaphragm actuator, and wherein the first corrugated diaphragm is configured for expanding outwardly when a positive pressure is applied within the cavity, wherein the at least one first corrugated channel has a depth measured in a direction parallel to the central longitudinal axis that varies along of the at least one first corrugated channel.
