Wearable triboelectric nanogenerators (TENGs) have recently attracted great interest because they can convert human biomechanical energy into sustainable electricity. However, there is a need for improvement regarding the output performance and the complex fabrication of TENG devices. Here, a triboelectric nanogenerator in single-electrode mode is fabricated by a simple strategy, which involves a sandwich structure of silicone rubber and silver-coated glass microspheres (S-TENG). The S-TENG exhibits a remarkable performance in harvesting human motion energy and as flexible tactile sensor. By optimizing the device parameters and operating conditions, the maximum open-circuit voltage and short-circuit current of the S-TENG can reach up to 370 V and 9.5 μA, respectively. The S-TENG with good stretchability (300%) can be produced in different shapes and placed on various parts of the body to harvest mechanical energy for charging capacitors and powering LED lights or scientific calculators. In addition, the good robustness of the S-TENG satisfies the needs of reliability for flexible tactile sensors in realizing human–machine interfaces. This work expands the potential application of S-TENGs from wearable electronics and smart sensing systems to real-time robotics control and virtual reality/augmented reality interactions.

“…Another important aspect of improving the tTENG for biosensing eld is to enhance the biocompatibility and sustainability of the materials used, in order to reduce waste and produce the environmentally-conscious nanogenerators of the future. Additionally, in anticipation of the future manufacturing and distribution of these devices, researchers need to make sure, via further testing, that implementation of the tTENGs into clothing for wearable applications will not alter the intrinsic characteristics of the clothing material, such as breathability, 244 and wearability. 151,245 Ultimately, researchers must continually consider the complexity, cost-effectiveness, scalable manufacturing, and efficiency of future.…”

“…[ 12 ] Among them, TENGs, as an emerging energy technique proposed in 2012, [ 13 ] can convert ubiquitous mechanical energy in the environment into electrical energy, and show an extensive potential in the field of biomechanical energy harvesting owing to its inherent virtues of low cost, high energy conversion efficiency, high power output, and abundant tribomaterial sources. [ 14–17 ] One of the essential problems for TENGs is their restricted output power that is unable to accomplish demands of wearable electronics. Many researches have verified that electric outputs of TENGs are mostly determined by the surface charge density.…”

Tribopositive, scalable, and biocompatible materials are highly desired for high‐performance triboelectric nanogenerators (TENGs). In this study, polyethylenimine (PEI) functionalized N‐doped carbon dots (NCDs‐PEI) are synthesized and a novel approach to develop high‐output TENGs by incorporating high permittivity NCDs‐PEI into polyvinyl alcohol (PVA) as the tribopositive composite (CPP composite) is proposed for the first time. By systematically manipulating the mass ratio of NCDs/PVA and PEI‐functionalized concentration, the optimized CPP composite‐based TENGs (CPP‐TENGs) reveal a remarkable enhancement in power density by 28.5 times as compared with pure PVA‐based TENGs. The considerable electric outputs of CPP‐TENGs can be attributed to the synergistic effect of interfacial polarization enhanced permittivity of CPP composite and boosted surface charge density induced by dual charge transfer pathways. Moreover, CPP‐TENGs present superior high‐output stability, durability, and humidity‐resistance, and can also effectively drive electronics at different humidity and monitor human body movements. This work renders a simple, feasible, and scalable pathway to boost the electrical performance of TENGs for biomotion energy harvesting as well as providing insights for exploiting novel tribomaterials in the development of high‐output TENGs.
