processing, and transmission of information. [1][2][3] Moreover, portable and wearable electronics for health monitoring and interactive communication are already widespread in our life. [4,5] Accordingly, the demanding energy for powering these electronics soars with time, especially the distributed and low-powered energy sources. [6,7] At present, the vast majority of power sources for needed electricity are different batteries, [8][9][10] which are widely used owing to their mature processing technology and low manufacturing cost. However, the batteries have the inherent drawbacks of a limited lifetime and capacity. [11,12] And there are some knotty problems of environmental pollution and recycling difficulty [13,14] when wearing out. Therefore, much effort has been devoted to exploring other types of sustainable and green energy sources like solar energy, wind energy, etc., which serve as a complement or replacement. [15] Since invented by Wang et al. [16] in 2012, the triboelectric nanogenerator [17][18][19][20] (TENG) has become the spotlight among researchers with great promising potential to be the following generation of energy. Based on the coupling effects of electrostatic induction and triboelectrification, [21][22][23] the TENG has merits of high efficiency, easy fabrication, various materials, and low cost. [22,[24][25][26] It has witnessed great progress and achievements in micro-nano energy, [27][28][29][30] self-powered systems, [26,[31][32][33][34][35][36][37][38] blue-ocean energy, [39][40][41][42] and high voltage applications.

[54] Through the corona charging, Zhou et al. [55] have enhanced the charge density to 240 µC m −2 . By highly packaged in vacuum, an ultrahigh charge density of 1003 µC m −2 is obtained by Wang et al., [54] yet leading to great difficulty for the device fabrication. Recently, the emerging contact-separated charge pump technology brings with a new bright prospect and a breakthrough to the bottleneck of charge As an emerging harvester for mechanical energy, the ultrahigh and unstable voltage and low surface charge density have limited the practical applications of triboelectric nanogenerators (TENGs). Herein, a charge pumping technology is demonstrated for sliding-mode TENG with voltage stabilization and enhanced current by utilizing unfixed shuttling charges to generate electricit...

Recapitulating the vascular networks that maintain the delivery of nutrition, oxygen, and byproducts for the living cells within the three-dimensional (3D) tissue constructs is a challenging issue in the tissue-engineering area. Here, a novel coaxial electrohydrodynamic (EHD) bioprinting strategy is presented to fabricate thick pre-vascularized cell-laden constructs. The alginate and collagen/calcium chloride solution were utilized as the outer-layer and inner-layer bioink, respectively, in the coaxial printing nozzle to produce the core-sheath hydrogel filaments. The effect of process parameters (the feeding rate of alginate and collagen and the moving speed of the printing stage) on the size of core and sheath lines within the printed filaments was investigated. The core-sheath filaments were printed in the predefined pattern to fabricate lattice hydrogel with perfusable lumen structures. Endothelialized lumen structures were fabricated by culturing the core-sheath filaments with endothelial cells laden in the core collagen hydrogel. Multilayer core-sheath filaments were successfully printed into 3D porous hydrogel constructs with a thickness of more than 3 mm. Finally, 3D pre-vascularized cardiac constructs were successfully generated, indicating the efficacy of our strategy to engineer living tissues with complex vascular structures.
