(a) Photograph of the MCN film thermistor that was prepared at 55 mJ·cm² of Kr laser irradiation on the PI sheet with Ag/carbon micro-pinecone (CMP) composite electrodes. (b) Temperature dependence of R (Ω) at 27–200°C for the MCN films on PI substrates prepared by drying at 200 °C and laser irradiation at 35–95 mJ·cm⁻² for 600 pulses. (c) FESEM images of the surface morphology of MCN films prepared by drying at 200 °C, and by KrF laser irradiation at 55 mJ·cm⁻² for 600 pulses. (d) Changes in resistance (R) during bending with a bending radius of 5 mm for patterned lines of the Ag/CMP composite and inkjet-printed Ag. Schematics of the Ag electrodes with, and without, CMP arrays on the flexible substrates in flat and bent states with FESEM images of patterned CMP and Ag/CMP composite on the polyimide substrate.
