Recent advances in soft electronics have attracted great attention due to its potential applications to personalized bio-integrated devices. The mechanical mismatch between conventional electronic devices and soft human tissues/organs oftentimes causes various challenges, such as the low signal to noise ratio of the biosensors, inflammations and/or excessive immune responses near the implanted sites, and unsatisfactory electrical/chemical feedback therapies. Ultra-flexible and stretchable electronic devices have a low system modulus, and thereby have a high potential to solve these issues. Nanomaterials and their composites with the soft elastomeric backbone matrix are particularly beneficial in realizing these ultra-flexible and stretchable bioelectronics. In this talk, our unique strategies in the synthesis of nanmaterials, material processing techniques for stretchable nanocomposites, and their unconventional biomedical device applications are presented. Furthermore, the integration of wireless technologies with such soft bioelectronic devices enables the long-term operation of the bio-integrated devices and customized point-of-care treatment under mobile environment.
