Power may be extracted from excitations ofthe undulations in a wide variety of ways, including via the utilization of a flexible material which exhibits an electrical responseto mechanical strain, whereby electricityisextracted via two or more electrodes. In
10、other implementations, power may beextracted via mechanical coupling of the undulations in the sheet-like material to a power-extracting output device, such as a rotatingmechanism which turns an electro-magnetic generator. In other implementations, mechanisms transfer energy from one movingfluid to
