Self-Healing Materials-Based Electronic Skin: Mechanism, Development and Applications

Abstract

Electronic skin (e-skin) has brought us great convenience and revolutionized our way of life. However, due to physical or chemical aging and damage, they will inevitably be degraded gradually with practical operation. The emergence of self-healing materials enables e-skins to achieve repairment of cracks and restoration of mechanical function by themselves, meeting the requirements of the era for building durable and self-healing electronic devices. This work reviews the current development of self-healing e-skins with various application scenarios, including motion sensor, human–machine interaction and soft robots. The new application fields and present challenges are discussed; meanwhile, thinkable strategies and prospects of future potential applications are conferenced.

Polydopamine Incorporation Enhances Cell Differentiation and Antibacterial Properties of 3D-Printed Guanosine-Borate Hydrogels for Functional Tissue Regeneration

“…Therefore, supramolecular hydrogels have the ability to remodel, reshape, and adapt to environmental conditions and changes. These dynamic features, such as stimuli responsiveness [ 4 , 5 ], self-healing [ 6 , 7 , 8 , 9 ], and shear thinning [ 10 ], are crucial for a variety of emerging applications including therapeutic delivery [ 11 , 12 , 13 , 14 ], tissue engineering [ 15 , 16 ], and bioimaging [ 17 ].…”

Effect of Zn2+ salt bonding on thermo‐reversible self‐healing natural rubber

“…Zn 2+ ion in the developed selfhealing NR has a similar function to Ca 2+ in hevein protein, which generated Zn 2+ salt bonding, thus serving as a platform for self-healing capabilities. 18,21 The developed interactions are also expected to be firmly attached between the rubber chains, resulting in high mechanical properties. 22,23 The present work assessed the formation of thermoreversible Zn 2+ salt bonding in the grafted methacrylic acid (MAA)-grafted NR.…”

Self-healable PEDOT-based all-organic films with excellent electrochromic performances

“…The generated scratches and cracks from damaging forces, or fatigue caused by repeated use during the process of running, can severely limit their long-term stability and application range. 8…”
