Modern light wearable electrical devices require flexible, conductive materials for the development of portable and/or wearable devices. In this study, a flexible carbon nanotube (CNT) electrode is prepared, and the conductive CNTs are deposited on a flexible polydimethylsiloxane (PDMS) substrate using a combination of inkjet printing and transfer printing methods. Aqueous CNT ink is printed on a commercial overhead projector film. The subsequent deposition of a thin PDMS layer and peeling the layer off resulted in the production of a flexible PDMS film with conductive CNT patterns. The thickness of the prepared electrode increased by ∼1.2 µm after every 10 prints, and the sheet resistance decreased rapidly from 14.7 MΩ/sq to 913 kΩ/sq after 20 and 50 prints, respectively. The construction of a simple foldable electrical circuit and its application to the electrochemical sensing of dopamine using flexible electrodes are demonstrated. These flexible electrodes can be easily fabricated while displaying designer functionality.
