Devices and methods are provided for harvesting kinetic energy. The devices can include a plurality of dielectric elastomeric membranes, a rigid connector rod, and a mountable support base. Membrane layers have a funnel-shape with a narrow opening portion and a wide perimeter portion. Membrane layers are adjacent to other membrane layers having an opposite orientation defined by the narrow opening portion and the wide perimeter portion. The narrow opening portions are coupled to a first end portion of the connector rod. The wide perimeter portions are fixed in relation to the support base. Application of linear force at a second end portion of the connector rod in a first direction causes at least a first membrane layer to stretch. Application of the force in a second direction opposite to the first direction causes at least a second membrane layer adjacent to the first membrane layer to stretch.

An apparatus is disclosed for extracting energy from an oscillating working fluid. The apparatus comprises a housing 50 which is positioned on a floatable support structure 120/130 that is arranged in use to float on a body of water having waves. The the housing has an internal flow passage for receiving air; and a turbine 60/70 which is disposed at the housing. A unidirectional flow of the air is drawn out of the chamber by the use of an OWC created by respective incoming and outgoing flows of waves. The unidirectional flow of the OWC acting on the turbine 60/70 is responsive to, and generated by, only one of the flows of the waves.
