摘要： The subject invention pertains to thermoelectric power generation. According to certain embodiments, a stack of silicon-micromachined chips can be connected to form a cylindrical heat exchanger that enables a large, uniform temperature difference across a radially-oriented thermopile. Each layer in the stack can comprise two thermally-isolated concentric silicon rings connected by a polyimide membrane that supports patterned thermoelectric thin films. The polyimide membrane can be formed by selectively etching away the supporting silicon, resulting in thermally-isolated inner and outer rings. In operation, hot gas can flow through a finned central channel, and an external cross flow can enhance heat transfer to ambient to keep the outer surfaces cool. The resulting temperature gradient across the thermopile generates a voltage potential across the open ends due to the Seebeck effect. When connected to a load, current flows, and electrical power is supplied by the generated voltage potential caused by the temperature gradient.

摘要： Devices and systems for power electronic circuits are provided. Embodiments of the present invention enable high density inductive energy storage by using electromechanical coupling between an electrically conducting inductive element and a mechanical resonator to passively store energy via both electromagnetic and mechanical mechanisms. A microelectromechanical inductor (MEMI) is provided utilizing a magnet and a conductor. In a specific embodiment, the MEMI includes a permanent magnet on a compliant layer centrally disposed within a spiral coil. In a further embodiment, a second coil is provided near the magnet to provide a resonating transducer.
