Flexible prototype thermoelectric devices based on Ag2Te and PEDOT:PSS coated nylon fibre

p-and n-type Ag2Te nanocrystals are coated separately onto nylon fibres to create flexible composites. A prototype thermoelectric device made using such fibres produces similar to 0.8 nW in a 20 K temperature difference. This is improved to over 5 nW by using a conducting polymer as the p-type material.
