“…[32,33,122,123] Solid-state supercapacitors with conventional device structure typically comprise of two electrodes and a gel electrolyte (acting as electrolyte and separator). Therefore, the realization of self-healing electrodes and self-healing gel electrolytes is the key challenge for the fabrication of self-healing supercapacitors.…”

Because of the great breakthroughs of self‐healing materials in the past decade, endowing devices with self‐healing ability has emerged as a particularly promising route to effectively enhance the device durability and functionality. This article summarizes recent advances in self‐healing materials developed for energy harvesting and storage devices (e.g., nanogenerators, solar cells, supercapacitors, and lithium‐ion batteries) over the past decade. This review first introduces the main self‐healing mechanisms among different materials including insulators, electrical conductors, semiconductors, and ionic conductors. Then, the basic concepts, fabrication techniques, and healing performances of the newly developed self‐healing energy harvesting (nanogenerators and solar cells) and storage (supercapacitors and lithium‐ion batteries) devices are described in detail. Finally, the existing challenges and promising solutions of self‐healing materials and devices are discussed.

“…On the contrary, recent research efforts establish an impressive alternatives to commercially available cylindrical, coin, prismatic, and pouch cells with flexible and stretchable batteries. [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] Nevertheless, such advances do not address the major necessities for implantable devices, especially in orthodontic dental implantations, which generally require: smaller footprint, lightness, high bio-compatibility, and finally integration strategy with other circuit components. Here, we show, a high yield, transfer-less method to achieve a bio-compatible, flexible, high-performance solid-state, micro-battery for wearable and implantable device electronics, specifically with an example potentially disruptive for orthodontics applications.…”

To augment the quality of our life, fully compliant personalized advanced health-care electronic system is pivotal. One of the major requirements to implement such systems is a physically flexible high-performance biocompatible energy storage (battery). However, the status-quo options do not match all of these attributes simultaneously and we also lack in an effective integration strategy to integrate them in complex architecture such as orthodontic domain in human body. Here we show, a physically complaint lithium-ion micro-battery (236 μg) with an unprecedented volumetric energy (the ratio of energy to device geometrical size) of 200 mWh/cm 3 after 120 cycles of continuous operation. Our results of 90% viability test confirmed the battery's biocompatibility. We also show seamless integration of the developed battery in an optoelectronic system embedded in a threedimensional printed smart dental brace. We foresee the resultant orthodontic system as a personalized advanced health-care application, which could serve in faster bone regeneration and enhanced enamel health-care protection and subsequently reducing the overall health-care cost.

“…[3][4][5] Given that the power source unit is an essential component of stretchable electronics, soft energy conversion and storage systems must be considered to meet the design and power needs of fully stretchable and deformable systems. [6][7][8][9] Transparent soft electronics are of interest in surface mountable applications that require the visibility of the supporting substrates. [10,11] This includes touch panels on light emitting surfaces, and moldable electronics or building fenestrations that connect occupants and the external environment.…”

The recent boom in deformable or stretchable electronics, flexible transparent displays/screens, and their integration into the human body has facilitated the development of multifunctional energy devices that are stretchable, transparent, wearable, and/or biocompatible while meeting the energy or power requirements. The development of soft energy systems begins with the preparation of relevant conductors and the design of innovative device configurations. In this study, recent advances and trends in stretchable and transparent electronic and ionic conductors are reviewed coupled with the growing efforts to use them for soft energy storage and conversion systems. Stretchable transparent ionic conductors present possibilities for use as current collectors and electrolytes in soft electronic/energy devices, providing novel insight into biofriendly systems for an effective human–machine interaction. Moreover, representative examples that demonstrate soft energy devices based on stretchable transparent ionic/electronic conductors are discussed in detail. Furthermore, the challenges and perspectives of developing novel stretchable transparent conductors and device configurations with tailored features are also considered.
