  • Self-corrugating laminates useful in the manufacture of thermoelectric devices and corrugated structures therefrom
    Patent number: 9064994
    Abstract: Self-corrugating laminates useful in the manufacture of thermoelectric devices are disclosed. The laminates include an upper and a lower shrinkable film layer and a non-shrinkable core with a thermoelectric pattern formed thereon bonded between said upper and lower shrinkable film along bond lines arranged parallel, substantially parallel, radially, or annularly. The bond lines that bond the upper shrinkable film layer to top surface of the nonshrinkable core are staggered relative to the bond lines that bond the lower shrinkable film layer to the bottom surface of the non-shrinkable core such that upon shrinkage of the shrinkable film layers, structural corrugations are formed in the non-shrinkable core. Thermoelectric modules or devices and methods for forming them from the self-corrugating laminates are also described.
