摘要： Disclosed are a high performance thermoelectric device and a method of manufacturing the same at ultra-high speed. The high performance thermoelectric device includes segmented structures which may provide an optimal match between the thermoelectric materials and the environmental temperature difference; blocking layers and stress-buffering layers which can reduce interface element migration and longitudinal contact thermal expansion stress and increase bonding strength; phonon scattering layers and negative thermal expansion buffering layers inserted and fixing the thermoelectric leg, thereby increasing internal thermal resistance and improving transverse thermo-match for the high performance thermoelectric device; an inner package and an outer package, thus avoiding sublimation and oxidation of the thermoelectric materials and providing the thermoelectric device with enhanced impact resistance from outside.

摘要： A thermoelectric device with multiple headers and a method of manufacturing such a device are provided herein. In some embodiments, a thermoelectric device includes multiple thermoelectric legs, a cold header thermally attached to the thermoelectric legs, and a hot header thermally attached to the thermoelectric legs opposite the cold header. At least one of the cold header and the hot header includes at least one score line. According to some embodiments disclosed herein, this the thermal stress on the thermoelectric device can be greatly reduced or relieved by splitting the header into multiple pieces or by scoring the header by a depth X. This enables the use of larger thermoelectric devices and/or thermoelectric devices with an increased lifespan.

摘要： Provided is a feedback device providing thermal feedback. The feedback device, according to one embodiment, may comprise a casing, a heat output module, and a feedback controller. The casing comprises: a contact part, with which a user makes contact when the feedback device moves when a content is being played; and a noncontact part with which the user does not make contact even though the feedback device moves. The heat output module comprises: flexible first and second substrates; a thermoelectric element interposed between the first the second substrates and performing a thermoelectric operation for thermal feedback; and a contact surface disposed on the second substrate. The heat output module is disposed on the curve-shaped inside or outside of the contact part, and outputs thermal feedback to the user via the second substrate and the contact surface. The feedback controller is configured so as to control the thermal output module.

摘要： A unique, environmentally-friendly micron scale autonomous electrical power source is provided for generating renewable energy, or a renewable energy supplement, in electronic systems, electronic devices and electronic system components. The autonomous electrical power source includes a first conductor with a facing surface conditioned to have a low work function, a second conductor with a facing surface having a comparatively higher work function, and a dielectric layer of not more than 200 nm in thickness sandwiched between the respective facing surfaces of the first conductor and the second conductor. The autonomous electrical power source is configured to harvest minimal thermal energy from any source in an environment above absolute zero. An autonomous electrical power source component is also provided that includes a plurality of autonomous electrical power source constituent elements electrically connected to one another to increase a power output of the autonomous electrical power source.

摘要： A system exchanges pressure and heat from a source stream to a sink stream. The system includes a source exchanger and a sink exchanger. The source exchanger includes a first pressure exchanger and a first heat exchanger. The first pressure exchanger converts pressure of the source stream to electrical energy. The first heat exchanger converts temperature from the source stream via a first temperature differential to electrical energy. The sink exchanger includes a second pressure exchanger and a second heat exchanger. The second pressure exchanger uses electrical energy received from the source exchanger to change a pressure of the sink stream. The second heat exchanger uses electrical energy received from the source exchanger to change a temperature of the sink stream. Related apparatus, systems, techniques, and articles are also described.
