All-Printed Flexible Hygro-Thermoelectric Paper Generator.

ABSTRACT: The conversion of ubiquitous hygrothermal resources into renewable energy offers significant potential for cable-free, self-powered systems that can operate worldwide without regard to climatic or geographic limitations. Here, an all-printed flexible hygro-thermoelectric paper generator is demonstrated that uses bifunctional mobile ions and electrons to make the moist-diffusion effect, the Soret effect, and the Seebeck effect work synergistically. In the ordinary hygrothermal settings, it generates an unconventional hygro-thermoelectric output pattern and shows almost a dozen-fold increase in positive hygro-thermopower of 26.70 mV K^-1 and also another negative hygro-thermopower of -15.71 mV K^-1 compared to pure thermopower. A single paper generator can produce a giant
