“…Device design which includes the selection of flexible and bendable components such as the electrodes are the key factors that affect the stability and efficiency of these devices. Buckling or fracture structured metallic films or conducting polymers are used on elastic substrates as the electrodes to achieve ultimate stretchability 50, 51, 52, 53, 54, 55, 56. Yang et al57 developed a unique method to develop elastic electrically conducting fibers for their stretchable, wearable photovoltaic devices which maintained a PCE as high as 7.13% under stretching.…”

Wearable electronic devices represent a paradigm change in consumer electronics, on‐body sensing, artificial skins, and wearable communication and entertainment. Because all these electronic devices require energy to operate, wearable energy systems are an integral part of wearable devices. Essentially, the electrodes and other components present in these energy devices should be mechanically strong, flexible, lightweight, and comfortable to the user. Presented here is a critical review of those materials and devices developed for energy conversion and storage applications with an objective to be used in wearable devices. The focus is mainly on the advances made in the field of solar cells, triboelectric generators, Li‐ion batteries, and supercapacitors for wearable device development. As these devices need to be attached/integrated with the fabric, the discussion is limited to devices made in the form of ribbons, filaments, and fibers. Some of the important challenges and future directions to be pursued are also highlighted.

“…Conventionally, indium tin oxide (ITO) film is a ubiquitous transparent electrode of optoelectronics due to excellent sheet resistance and transparency (10 Ω sq −1 at 90% transmittance), but its brittleness by ceramic nature limits its further application to deformable devices. [53,54] Therefore, potential alternative materials have been extensively studied for ST electrodes, including CNTs, [55][56][57][58][59][60][61][62][63] graphene, [64][65][66][67][68][69] metallic NWs, [16,36,47, metallic grid/nanostructure, [94][95][96][97][98][99][100] conducting polymers, [52,[101][102][103][104][105][106][107] and hybrid composites. [39,[108][109][110][111][112][113][114] The performances of STECs are summarized in Table 1.…”

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.

“…[5][6][7] The property requirements for stretchable electronics vary depending upon the final application. For example, 10 to ~30% of strain is reported to be needed for stretchable displays, 8 ~20% for flexible solar cells, 9 ~120% for super capacitors, 10 and ~100% for batteries 11 and dielectric elastomer actuators. 12 In each case, the strain should occur without significant mechanical or electrical failure.…”

Here, we report a simple way to prepare stretchable polypyrrole (PPy)-based actuator materials that can be operated over a wide dynamic strain range and generate useable actuation displacements and pressures. The stretchable actuators were prepared as a laminated composite of PPy and a gold-coated roughened rubber sheet. By manipulating the corrugated surface of the rubber substrate, the stretchability of PPy was greatly improved. Gold-coated rubbers could be stretched to 30 percent without significant change in electrical resistance. The corrugated PPy/gold/rubber laminates successfully showed -1 percents of actuation strain even when prestretched to 24 percent. The actuation strains were smaller than for similar free-standing PPy films and a detailed analysis of the effects of corrugation and of the rubber substrate are presented to predict actuation strain under various prestretch strains.
