We present a versatile nanotransfer printing platform for integrating functional nanostructures onto rigid, flexible, and three-dimensional substrates [1,2]. By leveraging engineered interfacial adhesion, water-bridge formation, and water-floating mechanisms, this approach achieves high-fidelity pattern transfer without toxic chemicals, adhesives, sacrificial layers, or high-temperature processing. It accommodates diverse materials and complex substrate geometries while preserving nanoscale resolution. We demonstrate its utility across smart contact lenses, patterned carbon nanotubes, SERS substrates, and wearable gas sensors [3]. Collectively, these results position the technique as a scalable manufacturing route for next-generation nanophotonic, sensing, and wearable devices.

We present programmable functional surfaces that precisely control optical, acoustic, and mechanical responses through rational structural design [4, 5, 6, 7]. By engineering metasurfaces, quasicrystal planar lenses, auxetic kirigami, and field-programmable architectures, these systems achieve multifunctionality without added complexity. This enables holographic light projection, two-dimensional ultrasound focusing, self-powered sensing, and reconfigurable shape morphing across diverse applications. Computational optimization further allows these responses to be tailored to user-specific requirements. Together, these approaches bridge structural engineering with intelligent functional design, establishing a versatile route toward next-generation photonic, acoustic, and soft robotic devices for wearables, robotics, and personalized healthcare.

We have developed hierarchical micro/nanostructures, including nanoribbon yarns and flexible inorganic frameworks that enhance energy harvesting, energy storage, and wearable electronic systems through rational structural engineering [8, 9, 10, 11].These complex architectures overcome conventional limitations in surface functionality, mechanical deformability, and electrochemical performance, enabling superhydrophobic triboelectric nanogenerators, water harvesting devices, high-energy-density fiber supercapacitors, and flexible thermoelectric yarns with scalable, robust fabrication. Precise control over hierarchical complexity maximizes surface area, charge transport, and functional integration across these platforms, bridging advanced manufacturing with next-generation wearable and sustainable energy technologies.
