With the rapid advancement in artificial intelligence, wearable electronic skins have attracted substantial attention. However, the fabrication of such devices with high elasticity and breathability is still a challenge and highly desired. Here, a route to develop an all-fiber structured electronic skin with a scalable electrospinning fabrication technique is reported. The fabricated electronic skin is demonstrated to exhibit high pressure sensing with a sensitivity of 0.18 V kPa −1 in the detection range of 0-175 kPa. This wearable device could maintain prominent sensing performance and mechanical stability in the presence of large deformation, even when the elastic deformation is up to 50%. The electronic skin is easily conformable on different desired objects for real-time spatial mapping and long-term tactile sensing. Besides, it possesses high gas permeability with a water vapor transmittance rate of 10.26 kg m −2 d −1 . More importantly, the electronic skin is capable of working in a self-powered manner and even serves as a reliable power source to effectively drive small electronics. Possessing several compelling features, such as high sensitivity, high elasticity, high breathability as well as being self-powered and scalable in fabrication, the presented device paves a pathway for smart electronic skins.

“…[42] Our group designed a fully stretchable bio-TENG with single-electrode structure that can be used to efficiently harvest the swinging energy of the leaf by using the leaf as the electron-donating layer. [43] The bio-TENG is flexible and stretchable, so it can be attached perfectly on the leaf surface, and the energy can be collected by using the triboelectric effect when other swing leaves contact the bio-TENG surface (Figure 6b,c). This design does not need to pick plant leaves or damage plant structure, so it will not have a significant impact on the plant, which represents a new nondestructive way for obtaining energy from nature.…”

In recent years, triboelectric nanogenerators (TENG) developed by coupling friction electrification and electrostatic induction between two kinds of materials with different triboelectric polarities have attracted much attention for their simple principles, diversified structure, miniaturization, and high energy conversion efficiency.

“…Such stretchable electrode can withstand a strain of about 15% without a remarkable resistance increase (Figure 5g). Researchers also attached this TENG on the leaves to monitor wind speed in the natural environment [26]. In contrast with previously described wavy-structure electrodes whose stretchability mainly depends on the pre-strain level, electrodes based on percolating networks or mixture of conductive materials with elastomers display strong dependence on the capacity of the overlapping of conductive materials in response to the applied strain.…”

Triboelectric nanogenerator (TENG), a recently emerging technology that is based on the combination of triboelectric effect and electrostatic induction, has been found to be a promising strategy to harvest large amount of underutilized and low-frequency mechanical energy. One major challenge for TENGs is that the practical application requires flexible, deformable, multifunctional materials to ensure its favorable accommodation to arbitrary surfaces or moving object or harsh environment. Recent research interests mainly focus on the design and fabrication of electrode materials for TENG, making it a perfect candidate for wearable power source. In this chapter, we will introduce a couple of recent achievements regarding highly flexible/deformable TENGs based on stretchable electrodes, including geometrically designed electrode, mixture of conductive materials with elastomeric materials and intrinsically stretchable electrode, etc. In addition, we will address stretchable and self-healing electrodes of flexible TENGs for potential wearable and implantable electronics.
