Figure Lengend Snippet: SEM images of particles with ( a ) large (>20 µm) and ( b ) small diameter (≪1 µm). Optical images of ( c ) printed thick thermoelectric ink for high aspect ratio TE pillars before the hot-pressing process, with 1 mm 2 in area and 500 µm in thickness, on glass fiber fabric, and ( d ) Keyence 3D optical image of printed TE on the fabric.

Article Snippet: Depending on the design of the weave and the material, fabrics have a certain degree of porosity and a large roughness over 100 μm (Fig. ), as determined using a Keyence optical surface profiler.

Figure Lengend Snippet: Schematics of printed thermoelectric layer on top of bare glass fiber fabric ( a ) and on Chitosan layer ( b ) used as a preliminary layer to smoothen the rough bare fabric. Optical surface profiles of bare glass fiber fabric ( c ) and printed Chitosan layer on top of glass fiber fabric ( d ) with their measured 3-dimensional surface images using a Keyence optical microscope (insets). SEM cross-sectional images of printed and hot-pressed samples on fabrics with thickness of 11 µm ( e ), 111 µm ( f ) and 395 µm ( g ). Plots of electrical conductivity as a function of thickness of the printed BST layers without ( h ) and with chitosan ( i ).
