Nanomaterials for soft wearable electronics

Nanomaterial-enabled soft wearable electronics have seen tremendous progress in recent years with a wide range of applications such as monitoring of personal health, human-machine interfaces, and electronic skin for robotics and prosthetics. Nanomaterials, compared with bulk materials, can better accommodate the flexibility and stretchability requirements for soft wearable electronics. Here, several major types of nanomaterials used for soft wearable electronics are reviewed including metal nanomaterials, metal compound nanomaterials, carbon nanomaterials, and hybrid nanomaterials. For each type of nanomaterials, representative soft wearable electronic devices are presented. Finally, the outlook and perspective in this emerging field of soft wearable electronics are summarized.
