Skin‐inspired wearable devices hold great potentials in the next generation of smart portable electronics owing to their intriguing applications in healthcare monitoring, soft robotics, artificial intelligence, and human–machine interfaces. Despite tremendous research efforts dedicated to judiciously tailoring wearable devices in terms of their thickness, portability, flexibility, bendability as well as stretchability, the emerging Internet of Things demand the skin‐interfaced flexible systems to be endowed with additional functionalities with the capability of mimicking skin‐like perception and beyond. This review covers and highlights the latest advances of burgeoning multifunctional wearable electronics, primarily including versatile multimodal sensor systems, self‐healing material‐based devices, and self‐powered flexible sensors. To render the penetration of human‐interactive devices into global markets and households, economical manufacturing techniques are crucial to achieve large‐scale flexible systems with high‐throughput capability. The booming innovations in this research field will push the scientific community forward and benefit human beings in the near future.

Intelligent energy generation from ambient environment by various nanogenerators is desirable to realize self-powered operation of electronics. By integrating two or more kinds of nanogenerators, a hybridized nanogenerator provides a possible solution to largely increase the total electric power, and thus has been considered as one of the most significant energy-related technologies. Here, emerging advancements in hybridized nanogenerators are summarized in terms of their structures, principles, and potential applications. In particular, one-structure-based coupled nanogenerators based on multifunctional energy-scavenging materials and the interface regulation of solar cells by inner nanogenerators are discussed. For potential applications in wearable electronics, the new progress on flexible hybridized nanogenerators is presented on the basis of stretchable and mechanically durable materials, substrates, and electrodes. With the advances highlighted here and the ongoing research efforts, the continuous breakthrough in hybridized nanogenerators for multiple energy scavenging and their extensive applications is foreseeable in the future.The electromagnetic effect and the triboelectric effect are two promising approaches for scavenging mechanical energy (e.g., wind energy, [14] biomechanical energy, [15] rotational energy, [16] and water wave energy [17] ). By integrating electromagnetic and triboelectric effects in one device, a mechanical motion can generate more electricity, showing potential in powering electronics with large power requirement, [14,[18][19][20] as shown in Figure 1. The fundamental of electromagnetic effect is the Faraday's law of electromagnetic induction with the relative movement between the magnet and the coil, while the triboelectric effect is based on the coupling of triboelectrification and electrostatic induction during the periodic contact/separation

The state‐of‐the‐art triboelectric nanogenerators (TENGs) are constructed with synthetic polymers, curtailing their application prospects and relevance in sustainable technologies. The economically viable transformation and engineering of naturally abundant materials into efficient TENGs for mechanical energy harvesting is meaningful not only for fundamental scientific exploration, but also for addressing societal needs. Being an abundant natural biopolymer, chitosan enables exciting opportunity for low‐cost, biodegradable TENG applications. However, the electrical outputs of chitosan‐based TENGs are low compared with the devices built with synthetic polymers. Here, we explore the facile molecular surface engineering in chitosan to significantly boost the performance of chitosan‐based TENG for enabling the practical applications, for example, self‐powered car speed sensor. The molecular surface engineering offers a potentially promising scheme for designing and implementing high‐performance biopolymer‐based TENGs for self‐powered nanosystems in sustainable technologies. We further explore for the first time the feasibility of data mining approaches to analyze and learn the acquired triboelectric signals from the car speed sensors and predict the relationship between the triboelectric signals and car speed values.
