Thermoelectric temperature sensors by printing with a simple office inkjet printer

摘要

We present printing thermoelectric temperature sensors on paper by using a simple office inkjet printer with three different conductive inks based on carbon nanotubes (CNTs), silver nanoparticles hybrid-composited with CNTs silver nanoparticle/CNTs (AgNPs/CNTs) and thermoelectric poly(3,4-ethylenedioxythiophene)- poly(styrenesulfonate) (PEDOT:PSS). Due to novel combination of electrical, mechanical and chemical properties of three distinct materials of carbon, silver metal and organic polymer: e.g., especially high flexible, high conductivity, non-reduction and low temperature curing, they showed superior materials for printable conductive ink especially for flexible paper substrate. Two dimensional temperature sensor printed on paper, showed improved Seebeck coefficients to 20 % than one of the recently published data, indicating enhancement of thermoelectric performance.
