Fabrication of fiber optoelectronic devices via conformal transfer of inkjet-printed carbon nanotube microelectrodes for smart wearable e-textile applications |
| 초록 |
A new strategy to prepare optoelectronic fiber devices including organic field-effect transistor and organic photodiode with a spirally wrapped carbon nanotube microelectrodes is proposed. Inkjet-printed carbon nanotube microelectrodes with desired microstructure on an agarose hydrogel is conformally transferred to functional microfiber surface. Organic field-effect transistors (OFETs) with conformal deposition of CNT microelectrodes exhibit a high performance that exceed the previous structural limitations and the electrical performance is maintained even after bending deformation. Furthermore, a fiber organic photodiode (OPD) consisting of bulk heterojunction (BHJ) layer and transparent CNT microelectrodes also exhibit a high responsivity and Ilight/Idark ratio. As a proof of concept, textile photoplethysmogram(PPG) bandage for real-time heart-rate monitoring is successfully demonstrated by integrating the flexible fiber OPD with LEDs into the textile. |
