“…At present, self-healing polymers employing PEDOT as electroconductive components have been reported. [15][16][17][18][19][20][21][22][23][24] However, these research generally were on the basis of commercial available poly (3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS), an aqueous dispersion purchased from Clevios™, and their films or elastomers. [15][16][17][18][19][20] Their self-healing attributed to water-driving swelling of thermoplastic and hydrophilic PSS À chains together with noncovalent hydrogen-bonding interactions, which can be enhanced if combining with heating.…”

Thermally healing capability of cracks and defects is important and urgent for the safe operation and life extending of electric materials and devices. Here, by the combination of thermally driven reversible Diels-Alder (DA) interaction and in-situ chemical oxidative polymerization of 3,4-ethylenedioxythiophene (EDOT), a series of intrinsically conductive poly(3,4-ethylenedioxythiophene) (PEDOT)/DA composites possess intrinsically self-healing property under lowtemperature (reverse DA reaction at 100 C; DA crosslinking at 60 C) stimulus were achieved. The crosslinking DA bonding reactions are multiple from the co-existence of pre-synthesized macromolecular polyurethane attached DA units (PU-DA) and 2,4-hexadiyne-1,6-diol (DADOL) in the films. PU-DA involved in the polymerization process of EDOT to endow PEDOT with outstanding solution-processability, uniform film making, and structural self-healing capability, while DADOL was added to enhance the cross bonding between polymer chains. This work will accelerate the research and application development of intrinsically self-healing conducting polymers for commercial capacitors, antistatic coatings, implantable, printable electronics, and so on.

“…In the second case, conducting polymers, such as poly(ethylenedioxythiophene) (PEDOT), polyaniline (PANI), polypyrrole (PPy) are mixed with insulating materials, which provide the mechanical characteristics needed for self-healing. [34][35][36][37][38] As these composites are often solutionprocessable, the relative amount of the components can be easily tuned to achieve a homogeneous material with the desired electrical conductivity and healing performance. Tunable electrical conductivity and mechanical properties, high stability in air and aqueous media, low cost, lightweight, flexibility, and, in some cases, biocompatibility make these materials attractive for numerous applications, such as energy harvesting devices, wearable and stretchable electronics, energy storage, electronic skin, and implantable devices (Figure 1).…”

Materials able to regenerate after damage have been the object of investigation since the ancient times. For instance, self‐healing concretes, able to resist earthquakes, aging, weather, and seawater have been known since the times of ancient Rome and are still the object of research. During the last decade, there has been an increasing interest in self‐healing electronic materials, for applications in electronic skin (E‐skin) for health monitoring, wearable and stretchable sensors, actuators, transistors, energy harvesting, and storage devices. Self‐healing materials based on conducting polymers are particularly attractive due to their tunable high conductivity, good stability, intrinsic flexibility, excellent processability and biocompatibility. Here recent developments are reviewed in the field of self‐healing electronic materials based on conducting polymers, such as poly 3,4‐ethylenedioxythiophene (PEDOT), polypyrrole (PPy), and polyaniline (PANI). The different types of healing, the strategies adopted to optimize electrical and mechanical properties, and the various possible healing mechanisms are introduced. Finally, the main challenges and perspectives in the field are discussed.

“…Dimethyl sulfoxide (DMSO) treated aqueous PEDOT:PSS was recrystallized for significant conduction enhancement during a hydrothermal process, [52,53] followed by a freeze-drying process to transform it into a 3D porous hydrogel with high water uptake capability. [54,55] By combining the two well-established techniques, we developed a 3D microporous, conductive scaffold with all requirements for the miniaturized MFC. Water-dispersed PEDOT:PSS has been widely used to engineer a non-conductive matrix or to form various solid films as a biocompatible, electrocatalytic electrode, [35,[56][57][58][59] but those PEDOT:PSS forms are not suitable for scaffold-free development of 3D bioanodes because of their great dependency on substrates.…”

major and accessory organs (e.g., stomach, intestines, liver, and pancreas etc.) that compose and support the GI digestive system perform their proper functions through mechanical, chemical, and biological activities. [3] The tract secretes metabolites, electrolytes, enzymes, proteins, ions, and gases to digest food. The presence, absence, and proportion of each of those components can be physiologically indicative of GI health and disorders. [4,5] Recent explorations of the GI tract's outstandingly functional microbiome, which communicates with the central nervous system and maintains the immune system, have provided a new perspective on human health and disease. The research promises the development of new screening and early diagnostic techniques. [1,[6][7][8] Upper GI endoscopy and colonoscopy have been widely used as common techniques for early detection and temporary treatment of bleeding, inflammation, and lesions by the insertion of a camera and dispensing devices attached to a flexible fiber-optic tube through the GI tract. [9] However, even with a very long tube, the endoscopic procedure is typically not thorough because many areas of the GI tract remain largely inaccessible. [5] The small intestine is typically six meters long, and it is difficult to access all of it even with the upper endoscopy and colonoscopy. Even advanced deep endoscopy requires very sophisticated skills and experts to precisely control a balloon insertion and inflation in the small intestine. [1,5] Moreover, endoscopic procedures are generally complex, unpleasant, timeconsuming, and expensive while requiring advanced equipment and different levels of sedation, which cannot be widely applicable in developing countries or resource-limited settings.Ingestible capsules have been developed to overcome these limitations and especially to access hard-to-reach regions of the small intestine. [4,5,10] The swallowable capsules can readily visualize and monitor abnormalities of the GI tract while passively moving down the tract via the peristaltic motion of the gut. [11] Moreover, as the GI tract provides a relatively large space and immune-tolerant environment compared to other human organs, [12] the development of the ingestible capsule requires Functioning ingestible capsules offer tremendous promise for a plethora of diagnostic and therapeutic applications. However, the absence of realistic and practical power solutions has greatly hindered the development of ingestible electronics. Microbial fuel cells (MFCs) hold great potential as power sources for such devices as the small intestinal environment maintains a steady internal temperature and a neutral pH. Those conditions and the constant supply of nutrient-rich organics are a perfect environment to generate longlasting power. Although previous small-scale MFCs have demonstrated many promising applications, little is known about the potential for generating power in the human gut environment. Here, this work reports the design and operation of a microbial biobattery capsule for ingesti...
