Zero-Interconnects Twin-Wires Networks for High-Density 4-Wire Characterization of Conducting Materials [data that support the findings] Nerio Andrés Montoya, Valeria Criscuolo, Andrea Lo Presti, Raffaele Vecchione, Christian Falconi The data have been divided in 4 folders as follows • “Raw_data” contains results obtained by using the JAVA software (before using MATLAB for further analysis) for the 3 different types of experiments (spread analysis, monitoring the sintering and temperature calibration ) • “Images” contains photos of 3 representative devices printed on Kapton, paper and photopaper taken with a scale; these photos have been used with ImageJ in order to determine the mean widths of the printed tracks (needed for estimating the sheet resistances) • “Software" contains o JAVA application for controlling a digital multimeter (Agilent 34411A or Agilent 34410A) and exporting as column of numbers saved as ".txt" file o MATLAB live-script files used to analyze the .txt files produced by the JAVA application in order to generate the results presented in the manuscript o Arduino firmware for controlling the Twin_Wires Systems • "Designs" contains the schematics, PCB designs (Gerber Files) and the Bill Of Materials (BOM) for the Twin_Wires Systems. These data allow to replicate the system. The folder also contains some other designs (resistor network used to calibrate/verify the system).


Steps to reproduce

The final results have been found by using the MATLAB live-script files with the corresponding raw data files. There are three MATLAB live-script files and, correspondently, three sets of different raw data files. Each MATLAB live-script file needs files stored in the same folder as the MATLAB live-script file or in the MATLAB search path. Each data file contains the information of a resistor network of 29 elements printed using SilverNP inks and a Voltera One circuit printer. The devices were printed over three different materials: Kapton (FlexPCB), photographic paper (PhotoP) and normal paper. The name of each file specifies the experiment, the precision for data acquisition, the sampling time, the material, the device number, and finally how many points where taken. For example the file name "RoomTemperature_1.0PLC_100ms_PhotoP_6_3000points.txt" provides the following information: Experiment: Room temperature. Data precision: 1.0PLC Sampling time: 100ms per point Material: Photo-paper Device number: 6 Number of Data points: 3000.
