Average number of wash cycles survived by unpackaged and packaged flexible CO and series resistors filaments -------------------------- METHODOLOGICAL INFORMATION -------------------------- Description of methods used for collection/generation of data: The CO flexible sensor response was measured directly from the sensors usiing pico logger ADC 20 datalogger and data were obatined using Pico log 6.2 software. The bending cycles were performed using bending rig with a bendng diameter of 5mm over which the flexible circuits were placed and bent automatically with a help of stepper motor controlled by arduino code and electrical connectivity of the circuit were measured mannualy using mutimeter for 1000 cycles until the circuit becomes open Similarly for washing cycle, the flexible circuits were put inside the washing machine and its elecrical connecitivity for each cycle until it reaches open circuit condition were measured mannualyusing multimeter The temperature of the the vacuum forming machine Formech 450DT were measured directly on the machine using infraref thermometer For the peeling test, the Tinius Oslen tensile tester was used for all the samples and the force required to measure the peel strength was obtained using the software Horizon Methods for processing the data: Software- or Instrument-specific information needed to interpret the data, including software and hardware version numbers: Gas sensor measurements - Pico logger ADC 20 data logger and software Picolog 6.2 Peel strength test - Tinius Oslen H25KS and software used is Horizon Standards and calibration information, if appropriate: Environmental/experimental conditions: Room temperature in the lab Describe any quality-assurance procedures performed on the data: People involved with sample collection, processing, analysis and/or submission: Ashwini Valavan -------------------------- DATA-SPECIFIC INFORMATION -------------------------- 1) CO flexible sensor response before and after encapsulation with Platilon U 4201 AU Number of variables: response Rs/R0 for four different concentrations of CO (19,34,45,and 65ppm) Number of cases/rows: Variable list, defining any abbreviations, units of measure, codes or symbols used: Sensor response (no unit) and concentration of CO in ppm Missing data codes: Specialized formats or other abbreviations used: 2) Bending Cycles Number of variables: average number of washing cycles withstand by Platilon U 4201AU encapsulated CO flexible sensor and 5k series resistor and unencapsulated CO flexible sensor and 5k series resistor Number of cases/rows: Variable list, defining any abbreviations, units of measure, codes or symbols used: Missing data codes: Specialized formats or other abbreviations used: 3) Washing cycles Number of variables: average number of washing cycles withstand by Platilon U 4201AU encapsulated CO flexible sensor and 5k series resistor and unencapsulated CO flexible sensor and 5k series resistor Number of cases/rows: Variable list, defining any abbreviations, units of measure, codes or symbols used: Missing data codes: Specialized formats or other abbreviations used: 4) Temperature evaluation of Formech 450DT Vacuuum forming machine Number of variables: Heat power in percentage and Temperature Number of cases/rows: Variable list, defining any abbreviations, units of measure, codes or symbols used: Heat power in percentage(%) and Temperature(ºC) Missing data codes: Specialized formats or other abbreviations used: 5) Peel strength test for Platilon U 4201AU on Kapton N after vacuum forming and heat gun Number of variables: Force and length Number of cases/rows: Variable list, defining any abbreviations, units of measure, codes or symbols used: Force (N) and length (mm) Missing data codes: Specialized formats or other abbreviations used: 6) Peel strength test for Platilon U 4201AU on Kapton E after vacuum forming and heat gun Number of variables: Force and length Number of cases/rows: Variable list, defining any abbreviations, units of measure, codes or symbols used: Force (N) and length (mm) Missing data codes: Specialized formats or other abbreviations used:
