Self‐Healing Devices: Intrinsically Stretchable and Self‐Healing Electroconductive Composites Based on Supramolecular Organic Polymer Embedded with Copper Microparticles (Adv. Electron. Mater. 9/2020)

Abstract

Inspired from the natural healing mechanism of human skin, a stretchable, self‐healing, and conductive composite is developed. As a wearable strain sensor, it exhibits an excellent performance in real‐time human motion detection. It shows the potentiality in wearable sensors and e‐skin applications. More details can be found in article number 2000527 by Hyungtak Seo and co‐workers.

Bioinspired Self‐healing Soft Electronics

“…Electronic conductors in self-healing soft electronics are usually constructed by filling conductive nanofillers, such as silver nanowires, silver nanoparticles, carbon nanotubes, and graphene, into self-healing polymers or hydrogels (Figure 3c i). [66][67][68][69][70] A typical application of self-healing conductor-based soft electronics is self-healing TENG. As depicted in Figure 3c ii, when a force is applied, the triboelectrically negative material and triboelectrically positive material come into contact, and the charge transfer from the positive material to the negative material, producing equivalent negative and positive charges on both surfaces.…”

Wearable Electronics Based on Stretchable Organic Semiconductors

“…[ 1–9 ] Notably, flexible and stretchable devices, which can be bent, twisted, compressed, folded, and even stretched without compromising their electrical performance, reliability, and integration, are emerging as promising candidates for next generation, human friendly wearable electronics because they can be conformably coated on human skin without discomfort from mismatches in mechanical properties between the human body and electronics.
