Thermoelectric devices with interface materials and methods of manufacturing the same are provided. A thermoelectric device can include at least one shunt, at least one thermoelectric element in thermal and electrical communication with the at least one shunt, and at least one interface material between the at least one shunt and the at least one thermoelectric element. The at least one interface material can comprise a plurality of regions comprising a core material with each region separated from one another and surrounded by a shell material. The interface material can be configured to undergo deformation under (i) a normal load between the at least one shunt and the at least one thermoelectric element or (ii) a shear load between the at least one shunt and the at least one thermoelectric element. The deformation can reduce interface stress between the at least one shunt and the at least one thermoelectric element.


The present invention relates to an electrothermal converter, which has at least one cold side and one warm side. Provision is made that all the components of the converter cope with the thermal loads appearing when the converter is operated and/or in particular maintains its mechanical stability.

A climate-controlled bed capable of adapting to the needs of a sleeper via a closed loop feedback control system is provided. The bed includes a thermoelectric energy source, a sensor configured to monitor a physiological temperature of a sleeper, and a control system that regulates a temperature of the bed via the thermoelectric energy source. The control system can utilize data from the sensor to determine optimal thermal needs of the sleeper. The control system can also vary the temperature of the bed during a sleep cycle based on at least one predetermined sleep factor, such as the natural circadian temperature cycle.

In certain embodiments, a battery thermal management system includes at least one battery, at least one thermoelectric device in thermal communication with the at least one battery, and a conduit comprising an inlet configured to allow a working fluid to enter and flow into the conduit and into thermal communication with the at least one thermoelectric device. The conduit further comprises an outlet configured to allow the working fluid to exit and flow from the conduit and away from being in thermal communication with the at least one thermoelectric device. The battery thermal management system can further include a first flow control device which directs the working fluid through the inlet of the conduit and a second flow control device which directs the working fluid through the outlet of the conduit. The first flow control device and the second flow control device are each separately operable from one another.


In certain embodiments, a thermoelectric assembly and method is provided that can be configured to be in thermal communication with a generally tubular first fluid conduit configured to allow a first fluid to flow through the first fluid conduit along a first direction. The thermoelectric assembly can extend at least partially around a perimeter of the first fluid conduit. The thermoelectric assembly can include a plurality of thermoelectric sub-assemblies aligned with one another along the perimeter of the first fluid conduit. Each thermoelectric sub-assembly can include a plurality of thermoelectric elements in parallel electrical communication with one another. Each thermoelectric sub-assembly can also include at least one shunt comprising a first portion and a second portion. The first portion can be in thermal communication with and mechanically coupled to the plurality of thermoelectric elements and be in thermal communication with at least one second fluid conduit. The second portion can be in thermal communication with and mechanically coupled to the first portion and have a curved surface in thermal communication with the first fluid conduit. Each thermoelectric sub-assembly can include a plurality of electrically insulating elements to prevent current flow in a plane perpendicular to the first direction between adjacent thermoelectric sub-assemblies.
