Abstract

The past decade has witnessed an emerging and fast-growing field on mechanically soft systems, ranging from soft materials (e.g. hydrogels) to soft devices (e.g. flexible electronics), and to soft functional systems (e.g. soft robotics). It is envisioned that soft systems will continue to thrive in the coming decades in academia and industrial communities. The launch of Soft Science is to provide the first dedicated platform for publishing research findings and to share the knowledge among the communities.

Summary

INTRODUCTION

Along with the rapid growth of the electronic industry, portable/wearable electronics including health monitors, electronic sensors, and human healthcare equipments are becoming a noticeable technological trend that has experienced rapid growth[1,2]. Due to the direct contact with human skin, active materials with high biocompatibility are desired, especially for implantable SCs[44,45,46] According to these requirements, the following sections summarize conventional “soft” electrode materials and recently developed “soft” electrode materials for WSCs, from the aspects of material properties and preparation strategies. Recent advanced research on graphenebased soft electrode for WSCs is reviewed
