Flexible Printed Thermoelectric Cooling Film

Thermoelectric cooling devices based on narrow bandgap semiconductors such as bismuth telluride are commercially available. They are solid state devices and thus do not have the large footprint and moving parts associated with vapor compression refrigeration systems; however, they operate with lower efficiency. They are well-suited for cooling small flat surfaces where one is more concerned with the form factor than efficiency. For many practical applications, these square ceramic tile thermoele...
