“…As can be seen from the first two cases (the shielding electrode of S-TENG is grounded/ungrounded) in Fig. 1j, the effective charge output between two bottom electrodes of S-TENG is rarely improved whether the shielding electrode is grounded or not, which also agrees with a previous report 43 . According to the formula of plate capacitance, charge conservation and the capacitance model of S-TENG device, we can get the relationship of transferred charge Q t and charge distribution on tribo-layers (Eq.…”

The sliding mode triboelectric nanogenerator (S-TENG) is an effective technology for in-plane low-frequency mechanical energy harvesting. However, as surface modification of tribo-materials and charge excitation strategies are not well applicable for this mode, output performance promotion of S-TENG has no breakthrough recently. Herein, we propose a new strategy by designing shielding layer and alternative blank-tribo-area enabled charge space-accumulation (CSA) for enormously improving the charge density of S-TENG. It is found that the shielding layer prevents the air breakdown on the interface of tribo-layers effectively and the blank-tribo-area with charge dissipation on its surface of tribo-material promotes charge accumulation. The charge space-accumulation mechanism is analyzed theoretically and verified by experiments. The charge density of CSA-S-TENG achieves a 2.3 fold enhancement (1.63 mC m−2) of normal S-TENG in ambient conditions. This work provides a deep understanding of the working mechanism of S-TENG and an effective strategy for promoting its output performance.

“…SLA utilizes an optical process to aggregate materials, which is usually suitable for processing flexible products with complex plane patterns and shapes. Yang et al 138 used an SLA-based 3D printer to prepare TENG backplane support layers with a special pattern and used a photopolymer resin composed of (meth)acrylate monomers, oligomers and a photoinitiator (Fig. 7(g)).…”

“…Additionally, UV curing‐based stereolithography (SLA) and digital light processing (DLP) have also been applied in the fabrication of nanogenerators (Figure 1C). 12‐15 In DLP, liquid form monomers or oligomers with a photoinitiator are mixed as the printing ink. During printing, the ink is either placed into a tank with a UV window on the bottom or spread layer by layer onto the UV window.…”

In the dawn of energy crisis and rising challenges in powering distributed low energy portable devices, nanogenerators, a class of mechanical energy harvesters is gaining increasing interest in fundamental research and commercial applications. Nanogenerators harvest energy by transducing mechanical energy into electric energy, the performance is highly related to the mechanical and electrical properties of the materials and devices. A typical nanogenerator consists of a substrate, a functional triboelectric active layer, electrode, and separator, which overall built‐up a three dimensional (3D) structure. 3D printing with its ability to form complex 3D structures possess coveted advantages in the development of nanogenerators. In this review, we introduce the importance of 3D structures for nanogenerators and explicitly discuss the different 3D printing methods and the ink formulation to tackle the challenges in 3D structured nanogenerators. Additionally, the principle and application of 4D printing in nanogenerator fabrication are critically highlighted.
