The advances in wearable/flexible electronics have triggered tremendous demands for flexible power sources, where flexible nanogenerators, capable of converting mechanical energy into electricity, demonstrate its great potential. Here, recent progress on flexible nanogenerators for mechanical energy harvesting toward self‐powered systems, including flexible piezoelectric and triboelectric nanogenerator, is reviewed. The emphasis is mainly on the basic working principle, the newly developed materials and structural design as well as associated typical applications for energy harvesting, sensing, and self‐powered systems. In addition, the progress of flexible hybrid nanogenerator in terms of its applications is also highlighted. Finally, the challenges and future perspectives toward flexible self‐powered systems are reviewed.

“…Currently, microbatteries (MBs) and micro‐supercapacitors (MSCs) are two representative microscale electrochemical energy storage devices, which can be manufactured on the micro/nanoscale to be directly coupled with microelectronics as standalone microscale power sources or complement miniaturized energy harvesters, such as solar cells and nanogenerators, mitigating the discontinuity, periodicity, and indeterminacy of renewable solar and mechanical energy. Such unitized microscale power sources or self‐powered integrated microsystems are being deemed as necessary requirements for environmental, health, medical, industrial monitoring, and military applications . Notably, most microelectronics can be normally operated with low power, ranging from nanowatts to milliwatts, while with continuous boom of microelectronics high specific energy (per area or volume) of MBs and MSCs is being given top priority to run them for extended periods of time .…”

The rapid development and further modularization of miniaturized and self‐powered electronic systems have substantially stimulated the urgent demand for microscale electrochemical energy storage devices, e.g., microbatteries (MBs) and micro‐supercapacitors (MSCs). Recently, planar MBs and MSCs, composed of isolated thin‐film microelectrodes with extremely short ionic diffusion path and free of separator on a single substrate, have become particularly attractive because they can be directly integrated with microelectronic devices on the same side of one single substrate to act as a standalone microsized power source or complement miniaturized energy‐harvesting units. The development of and recent advances in planar MBs and MSCs from the fundamentals and design principle to the fabrication methods of 2D and 3D planar microdevices in both in‐plane and stacked geometries are highlighted. Additonally, a comprehensive analysis of the primary aspects that eventually affect the performance metrics of microscale energy storage devices, such as electrode materials, electrolyte, device architecture, and microfabrication techniques are presented. The technical challenges and prospective solutions for high‐energy‐density planar MBs and MSCs with multifunctionalities are proposed.

HIGHLIGHTS• Owing to the great robustness, continuous conductivity, and geometric construction of a steel wire electrode, the FST-TENGs demonstrate high stability, stretchability, and even tailorability.• By knitting several FST-TENGs to be a fabric or a bracelet worn on the human body, it enables to harvest human motion energy.• The FST-TENGs can also be woven on dorsum of glove to monitor the movements of gesture.ABSTRACT Continuous deforming always leads to the performance degradation of a flexible triboelectric nanogenerator due to the Young's modulus mismatch of different functional layers. In this work, we fabricated a fiber-shaped stretchable and tailorable triboelectric nanogenerator (FST-TENG) based on the geometric construction of a steel wire as electrode and ingenious selection of silicone rubber as triboelectric layer.Owing to the great robustness and continuous conductivity, the FST-TENGs demonstrate high stability, stretchability, and even tailorability. For a single device with ~ 6 cm in length and ~ 3 mm in diameter, the open-circuit voltage of ~ 59.7 V, transferred charge of ~ 23.7 nC, short-circuit current of ~ 2.67 μA and average power of ~ 2.13 μW can be obtained at 2.5 Hz. By knitting several FST-TENGs to be a fabric or a bracelet, it enables to harvest human motion energy and then to drive a wearable electronic device. Finally, it can also be woven on dorsum of glove to monitor the movements of gesture, which can recognize every single finger, different bending angle, and numbers of bent finger by analyzing voltage signals.
