摘要: Abstract In order to build upon the exceptional interest for flexible sensors based on carbon nanotube networks (CNNs), field requires high device-to-device reproducibility. Inkjet printing has provided outstanding results ohmic in terms of reproducibility their resistance. However, sensitivity, most critical parameter sensing application, been only marginally assessed. present paper, CNN-based resistive strain fabricated by inkjet-printing Ethylene Tetrafluoroethylene (EFTE) sheets are presented. The variability device initial resistance is studied 5 different batches from 3 72 devices each. ranges between 8.4% and 43% depending size batches, with a 20% average. An 8-device batch 15% further thermal sensitivity. Standard deviation values found be as low 16% sensitivity 8% temperature Moreover, hysteresis free, rare achievement CNT plastics.
