To achieve the soft and stretchable nature in high performance electronics and to apply this technology to wearable biomedical electronics/optoelectronics/soft-robotics, several strategies need to be employed, such as the designed assembly of high-quality nanomaterials and new design of individual devices with deformable structures. We seek to develop novel nanocomposites and their printing technologies by controlling their interfacial properties to achieve multidimensional form factors and deformability while maintaining the unique optical/electrical/mechanical properties of each nanomaterial. We want to develop high performance wearable/implantable electronic devices and soft robots to improve human life and well-being.
