Organic Flexible Electronics for Innovative Applications in Electronic Skin

The emergence of cutting-edge cross-disciplines has motivated the rapid development of wearable technology and flexible electronics. The flexibility and tunable properties of organic materials enable organic flexible electronics to adapt to complex surface deformations and achieve sensitive detection of physiological signals. The cost-effectiveness of organic materials in mass production offers additional possibilities for the practical and commercialization of e-skin technology. However, how to ensure stability and long-term reliability while maintaining a highly sensitive, flexible, and stretchable is a challenge for e-skins. In this review, the research progress and development trend of e-skin is systematically summarized, especially the latest breakthroughs and innovations in the frontier of organic flexible electronics, and systematically review the applications of e-skin in sensors, physiological monitoring, and energy supply. In addition, the review further discusses the prospects and current challenges for the application of organic flexible electronics in e-skin, which provides a one-stop reference for the development of e-skin.
