摘要:
The invention describes devices for performing thermodynamic work on a fluid, such as pumps (340), compressors and fans. The thermodynamic work may be used to provide a driving force for moving the fluid. Work performed on the fluid may be transmitted to other devices, such as a piston in a hydraulic actuation device. The devices may include one or more electroactive polymer transducers (341) with an electroactive polymer (341) that deflects in response to an application of an electric field. The electroactive polymer (341) may be used to perform thermodynamic work on the fluid. The devices may be designed to efficiently operate at a plurality of operating conditions, such as operating conditions that produce an acoustic signal above or below the human hearing range. The devices may be used in thermal control systems, such as refrigeration system, cooling systems and heating systems.
摘要:
Disclosed generators include one or more transducers that use electroactive polymer films to convert mechanical energy to electrical energy. The generators may include one or more transmission mechanisms that transfer a portion of an unused environmental energy source to the one or more transducers located in the generators. The energy received by the transducers may be converted to electrical energy by the transducers in conjunction with conditioning electronics located within the generator.
