  • Publication number: 20110315181
    Abstract: A method for converting heat to electricity by exploiting changes in spontaneous polarization that occur in electrically polarizable materials is described. The method uses an internally generated field to achieve poling during cycling. The internal poling field is produced by retaining residual free charges on the electrodes at the appropriate point of each cycle. The method obviates the need for applying a DC voltage during cycling and permits the use of the electrical energy that occurs during poling rather than an external poling voltage which detracts from the net energy produced per cycle. The method is not limited to a specific thermodynamic cycle and can be used with any thermodynamic cycle for converting heat to electricity by thermally cycling electrically polarizable materials. The electrical energy generated can be used in various applications or stored for later use. An apparatus for converting heat to electricity is also described.

    Abstract: 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.

  • Patent number: 7875791
    Abstract: A method for manufacturing thermopile carrier chips comprises forming first type thermocouple legs and second type thermocouple legs on a first surface of a substrate and afterwards removing part of the substrate form a second surface opposite to the first surface, thereby forming a carrier frame from the substrate and at least partially releasing the thermocouple legs from the substrate, wherein the thermocouple legs are attached between parts of the carrier frame. First type thermocouple legs and second type thermocouple legs may be formed on the same substrate or on a separate substrate. In the latter approach both types of thermocouple legs may be optimised independently. The thermocouple legs may be self-supporting or they may be supported by a thin membrane layer. After mounting the thermopile carrier chips in a thermopile unit or in a thermoelectric generator, the sides of the carrier frame to which no thermocouple legs are attached are removed.
