Compact Setup For Simo Measurements Of Slab Interconnects And Correlation With Pedot:Pss Nanostructure Morphology

We demonstrate a compact, portable and reliable, poor-man's 8-channel interconnect and measure, in the 50-100MHz VHF radiofrequency range, the path-dependent voltage transfer function across drop-cast poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS). The setup may be inexpensively deployed for singleinput-multiple-output (SIMO) self-sensing materials with computational impedance tomography algorithms. We test our setup with PEDOT:PSS samples that are dried in a static magnetic field. These samples exhibit anisotropic electrical conductivities and nanostructure morphologies. Voltages across the sample vary 2dB as a result of this anisotropy. This processing-dependent anisotropy of PEDOT:PSS may be useful in future efforts aimed at deconvolving the path-dependent electrical tomography measurements, as necessary for such a sensing system.
