“…Nevertheless, the stretchability is limited by the fact that the percolated networks of conductive fillers are broken at large strain 21. Alternatively, TENGs with ultrahigh stretchability have been reported by using ionic conductors of hydrogels or ionogels 22–34. Hydrogels are composed of hydrophilic polymer networks swollen with water or ionic aqueous solution, which can be stretchable, biocompatible and transparent 35–37.…”

The development of stretchable/soft electronics requires power sources that can match their stretchability. In this study, a highly stretchable, transparent, and environmentally stable triboelectric nanogenerator with ionic conductor electrodes (iTENG) is reported. The ion-conducting elastomer (ICE) electrode, together with a dielectric elastomer electrification layer, allows the ICE-iTENG to achieve a stretchability of 1036% and transmittance of 91.5%. Most importantly, the ICE is liquid solvent-free and thermally stable up to 335 °C, avoiding the dehydration-induced performance degradation of commonly used hydrogels. The ICE-iTENG shows no decrease in electrical output even after storing at 100 °C for 15 h. Biomechanical motion energies are demonstrated to be harvested by the ICE-iTENG for powering wearable electronics intermittently without extra power sources. An ICE-iTENGbased pressure sensor is also developed with sensitivity up to 2.87 kPa −1 . The stretchable ICE-iTENG overcomes the strain-induced performance degradation using percolated electrical conductors and liquid evaporationinduced degradation using ion-conducting hydrogels/ionogels, suggesting great promising applications in soft/stretchable electronics under a relatively wider temperature range.

Triboelectric nanogenerators have been used to drive and produce self-powered DEAs 43 and EAs. 44 One possible solution to an all-soft untethered ElectroSkin crawler is to combine a further optimized ElectroSkin design with stretchable triboelectric nanogenerators, 45 which will be investigated in the future.…”

Human skins are active, smart, and stretchable. Artificial skins that can replicate these properties are promising materials and technologies that will enable lightweight, cost-effective, portable, and deployable soft devices and robots. We show an active, stretchable, and portable artificial skin (ElectroSkin) that combines dielectric elastomer actuators (DEAs) and soft electroadhesives (EAs) in a fully compliant multilayer composite skin-like structure. By taking advantage of the common characteristics of DEA and EA, we define regions of the composite artificial skin as either active or passive. Active areas can be exploited as electromechanical actuators or as electrostatic gripper elements, or both simultaneously. This embedded multimodality delivers a new technology of deformable active skins that can grip and move objects and self-locomote. ElectroSkins can be fabricated using all-soft elastomers and readily available conductive materials. We demonstrate their capabilities in the first soft self-actuating conveyor belt, with a conveyoring speed of 0.28 mm/s, and a pocketable fully soft crawler robot. This new, self-actuating, self-gripping, and self-locomoting soft artificial skin has the potential to significantly impact on functional soft-smart composites, deployable robots, soft-smart conveyoring, and compliant gripping and manipulation applications.

Wearable and implantable electronics (WIEs) are more and more important and attractive to the public, and they have had positive influences on all aspects of our lives. As a bridge between wearable electronics and their surrounding environment and users, sensors are core components of WIEs and determine the implementation of their many functions. Although the existing sensor technology has evolved to a very advanced level with the rapid progress of advanced materials and nanotechnology, most of them still need external power supply, like batteries, which could cause problems that are difficult to track, recycle, and miniaturize, as well as possible environmental pollution and health hazards. In the past decades, based upon piezoelectric, pyroelectric, and triboelectric effect, various kinds of nanogenerators (NGs) were proposed which are capable of responding to a variety of mechanical movements, such as breeze, body drive, muscle stretch, sound/ultrasound, noise, mechanical vibration, and blood flow, and they had been widely used as self-powered sensors and micro-nanoenergy and blue energy harvesters. This review focuses on the applications of self-powered generators as implantable and wearable sensors in health monitoring, biosensor, human-computer interaction, and other fields. The existing problems and future prospects are also discussed.
