Figure Lengend Snippet: 3D illustrations of the two methods for printing 3D microelectrode arrays: ( a , b ) stationary and ( c , d ) continuous.

Article Snippet: 3D microelectrode arrays (MEAs) were printed on a 125 μm thick polyethylene naphthalate (PEN) film (Teonex Q65HA, DuPont Teijin Films, Wilton, UK) using a silver nanoparticle ink (Silverjet DGP 40LT-15C, Sigma-Aldrich, St. Louis, MO, USA) with a state-of-the-art inkjet printer (CeraPrinter F-Series, Ceradrop, Limoges, France).

Figure Lengend Snippet: Tilt-corrected scanning electron microscope images of ( a ) a sintered 3D microelectrode array, ( b ) a pillar under focused ion beam analysis, and ( c ) a pillar after bulk milling and polishing. Different magnifications of the pillar shown in ( c ) are shown in ( d – f ). All pillars were printed with approx. 1600 droplets of AgNP ink, displaying a width of ~32 μm and a height of 500–560 μm. All images were captured using an acceleration voltage of 3 kV and a substrate tilted at 52–54°. Scale bars represent ( a ) 500 μm, ( b ) and ( c ) 100 μm, ( d ) 10 μm, ( e ) 1 μm, and ( f ) 100 nm.

Figure Lengend Snippet: ( a ) Magnitude and ( b ) phase of the impedance of electroplated Ag-Au-Pt 3D microelectrodes, which were printed with different droplet numbers. The mean and standard deviation (solid line and shaded area, respectively) were calculated using 4 samples. ( c – l ) Tilt-corrected SEM images of the same 3D microelectrodes taken at a substrate tilt of ( c – g ) 0° and ( h – l ) 45°. All SEM images used an acceleration voltage of 15 kV. A magnification of ( c – j ) 1000×, ( k ) 350×, and ( l ) 250× was used. All scale bars shown have a length of 40 μm. The numbers in the legend and the upper right corner of the SEM images correspond to the amount of ejected Ag nanoparticle droplets.
