Hydrogel-Templated Transfer-Printing of Conductive Nanonetworks for Wearable Sensors on Topographic Flexible Substrates |
| 초록 |
Transfer-printing is an effective method to provide functional nanomaterials on non-traditional substrates with designed patterns. However, it still remains challenging to assemble nanomaterials on diverse topographic surfaces. Here, we show that hydrogels effectively serve as template material platforms for both the assembly and transfer-printing of conductive nanostructured patterns on diverse substrates. The hydrogel-templated assembly and transfer-printing were developed by systematically controlling nanoporous structure, the non-adherence, molding capability of the hydrogel. Not only pressure sensors, but also flexible strain sensors as monitoring devices of arterial pulses and finger movements were successfully shown. This work could lay groundwork for additive technology for hydrogels, as well as electronic materials for wearable devices and upcoming next-generation functional materials. |
