Abstract
Long-term continuous monitoring of body condition from the skin has been one of the critical issues in the ubiquitous healthcare. For this purpose, skin-like stretchable and flexible electrodes have been highly required and diverse electrodes have been developed. However, these electrodes have limits such as lower electrical property, biocompatibility, and discomfort to patients. To address these challenges, nanomaterial-based electronic devices have been developed. In this chapter, current status of nanomaterial-based skin-like electronics with mechanical properties comparable to those of skin is reviewed, and their applications in biomedical fields are described. The types of clinically significant biosignals that can be measured from skin using soft electrodes are briefly summarized. The requirements of electrode for long-term, continuous, and unconscious measurement of these biosignals are also briefly described. Among several nanomaterials for soft electronics, carbon nanotube (CNT), graphene, and metallic nanowire are mainly commented and diverse flexible and stretchable electrodes using nanomaterials and their fabrication methods were described. For the biomedical applications, safety for the human use is a critical requirement, and their biocompatibility, future research directions, and possible additional applications in various fields are assessed.
