Organic thermoelectric(TE) materials are a breakthrough for powering portable and wearable electronic devices. However, utilizing waste heat from practical heat sources, such as the human body, has been a challenge. This study introduces a method for patch-type TE materials which can form efficient thermal contact with various heat sources, including those with different surfaces and textures. TE patches comprise CNTs, PEDOT:PSS, and a commercial gel polymer blend, which forms freestanding hydrogel nanocomposite films. Under optimized conditions, TE patch exhibits good mechanical properties, as well as TE properties and long-term air stability. Surface-conformable TE patch drives superior thermal contact with arbitrary substrates, leading to more efficient energy harvesting than non-conformable patches. This indicates the potential application of organic TE materials in self-powered wearable electronics goes beyond energy harvesting and can also include precise temperature sensing.
