PEDOT:PSS-polyethylene oxide composites for stretchable and 3D-Printed thermoelectric devices

We developed poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) and polyethylene oxide composites demonstrated their use for soft stretchable thin film thermoelectric devices. A stable performance can be observed under 20% stretching. Due to the vast processability of polymer, bulk size devices produced with scalable manufacturing techniques, such as hot compression molding 3D printing. These techniques allow a large area customized geometry.
