Outline of Annual Research Achievements |
Soft electronics, referring to electronic devices that are flexible, stretchable, and/or conformable to arbitrary surfaces, are expected to bring about a radical transformation in the period of the industrial revolution owing to their unparallel potential for numerous applications in advanced manufacturing fields. However, fabricating soft electronics that can replace existing products and be put into service in our daily lives is a grand challenge due to the lack of sustainable fabrication processes and competitive performance. Using an independently developed dual-surface-architectonic (DSA) strategy, a novel technology for solid-liquid interfacial engineering has been further demonstrated this year. This technology enables the spontaneous patterning of one-dimensional (1D) functional nanomaterials on polymer substrates in an ordered and scalable manner under ambient conditions. The unique liquid-solid interaction has been thoroughly explored and applied in the practical fabrication of cross-linked silver nanowires (AgNW) soft circuits as well as stretchable tension sensors with prominent conductivity and deformability. This breakthrough opens up new possibilities for liquid-mediated self-assembly technologies in the sustainable manufacturing of soft electronics, particularly for highly conformable skin-integrated sensor devices.
