Abstract Triboelectrification is a well-known phenomenon that commonly occurs in nature and our lives at any time place. Although each every material exhibits triboelectrification, its quantification has not been standardized. A triboelectric series qualitatively ranked with regards to polarization. Here, we introduce universal standard method quantify the for wide range of polymers, establishing quantitative triboelectrification as fundamental materials property. By measuring tested liquid...
Contact-electrification is a universal effect for all existing materials, but it still lacks quantitative materials database to systematically understand its scientific mechanisms. Using an established measurement method, this study quantifies the triboelectric charge densities of nearly 30 inorganic nonmetallic materials. From matrix their and band structures, found that output strongly related work functions Our verifies contact-electrification electronic quantum transition under ambient...
The development of flexible and stretchable electronics has attracted intensive attention for their promising applications in next‐generation wearable functional devices. However, these devices that are made a conventional planar format have largely hindered development, especially highly conditions. Herein, novel type stretchable, fiber‐based triboelectric nanogenerator (fiber‐like TENG) power generation is developed. Owing to the advanced structural designs, including fiber‐convolving...
Abstract With the rapid development of Internet things (IoT), flexible piezoelectric nanogenerators (PENG) have attracted extensive attention for harvesting environmental mechanical energy to power electronics and nanosystems. Herein, porous fillers with samarium/titanium‐doped BiFeO 3 (BFO) are prepared by a freeze‐drying method, then silicone rubber is filled into microvoids ceramics, forming unique structure based on matrix uniformly distributed ceramic. When subjected external force...
A large coercive field (EC) and ultrahigh piezoelectricity are essential for ferroelectrics used in high-drive electromechanical applications. The discovery of relaxor-PbTiO3 crystals is a recent breakthrough; they currently afford the highest piezoelectricity, but usually with low EC. Such performance deterioration occurs because high interlinked an easy polarization rotation, subsequently favoring dipole switch under small fields. Therefore, search both EC has become imminent challenge....
Harvesting energy available from ambient environment is highly desirable for powering personal electronics and health applications. Due to natural process human activities, steam can be produced by boilers, perspiration, the wind exists ubiquitously. In outdoor environment, these two phenomena usually exist at same place, which contain heat mechanical energies simultaneously. However, previous studies have isolated them as separate sources of harvest hence failed utilize effectively. Herein,...

Abstract Urban sound management is required in a variety of fields such as transportation, security, water conservancy and construction, among others. Given the diverse array available noise sensors widespread opportunity to connect these via mobile broadband Internet access, many researchers are eager apply sound‐sensor networks for urban management. Existing sensing typically consist expensive information‐sensing devices, cost maintenance which limit their large‐scale, ubiquitous...
Abstract 2D piezoelectric materials have strong intrinsic piezoelectricity and superior flexibility, which are endowed with huge potential to develop nanogenerators (PENGs). However, there few attempts investigate the energy harvesting of ferroelectric materials. Herein, an enhanced output performance is reported by polarization in a PENG exfoliated CuInP 2 S 6 (CIPS). Specifically, polarized CIPS‐based produces short‐circuit current 760 pA at 0.85% tensile strain, 3.8 times higher than that...
