“…To address the above issues, a number of groups have reported the development of stretch‐matched liquid electrode‐based TENGs that exhibit antifreezing properties; this was achieved by integrating a lithium chloride electrolyte, graphene oxide, and ethylene glycol. [ 29 ] In addition, a low temperature‐resistant hydrogel has been designed based on the polymerization of an acrylamide monomer in an aqueous solution of hydroxyethyl cellulose to provide an electrode for TENG applications. However, the above devices did not exhibit self‐healing properties following damage at low temperature, and so the combination of both properties for application in subzero temperatures or high humidity/dry climates remains the challenge.…”

Due to the ongoing development of portable/mobile electronics, sources to power have received widespread attention. Compared to chemical batteries as power sources, triboelectric nanogenerators (TENGs) possess lots of advantages, including the ability to harvest energy via human motions, flexible structures, environment‐friendliness, and long‐life characteristics. Although many self‐healable TENGs are reported, the achievement of a muscle‐like elasticity and the ability to recover from inevitable damage under extreme conditions (such as a high/low temperature and/or humidity) remain a challenge. Herein, a “double‐terminal aromatic disulfide” on a structure with zwitterions as branched chains is reported to engineer the high‐efficient self‐healable elastomer for application in a flexible TENG. The as‐designed material exhibits a repeatable elastic recovery (at 250% elongation) and a self‐healing efficiency with an ultimate tensile stress of 96% over 2 h, representing an improvement on previously reported disulfide‐based elastomers. The elastomer can autonomously recover by 50% even at a subzero temperature of −30 °C within 24 h. The elastomer‐based TENG, as a self‐driven sensor for detecting human behavior, is demonstrated to exhibit stable outputs and self‐healing in the temperature range of −30 to 60 °C, and so is expected to promote the development of self‐powered electronics for next‐generation human–machine communications.

“…Specifically, one single stimulus is able to produce both electrical and optical signals at the same time, which is only drove by mechanical forces (no external power supply is required). The MTBS is a typical layer-by-layer structure which consists of three parts from top to bottom based on the contact-separation mode TENG [ 38 ]. The top layer is ML elastomer consisting of PDMS with well-dispersed ZnS:Cu particles, which can produce optical signal under external force.…”

Mechanoluminescent-Triboelectric Bimodal Sensors for Self-Powered Sensing and Intelligent Control

Self-powered flexible devices with skin-like multiple sensing ability have attracted great attentions due to their broad applications in the Internet of Things (IoT). Various methods have been proposed to enhance mechano-optic or electric performance of the flexible devices; however, it remains challenging to realize the display and accurate recognition of motion trajectories for intelligent control. Here, we present a fully self-powered mechanoluminescent-triboelectric bimodal sensor based on micro-nanostructured mechanoluminescent elastomer, which can patterned-display the force trajectories. The deformable liquid metals used as stretchable electrode make the stress transfer stable through overall device to achieve outstanding mechanoluminescence (with a gray value of 107 under a stimulus force as low as 0.3 N and more than 2000 cycles reproducibility). Moreover, a microstructured surface is constructed which endows the resulted composite with significantly improved triboelectric performances (voltage increases from 8 to 24 V). Based on the excellent bimodal sensing performances and durability of the obtained composite, a highly reliable intelligent control system by machine learning has been developed for controlling trolley, providing an approach for advanced visual interaction devices and smart wearable electronics in the future IoT era.

The convenient use of energy harvesting techniques has been a bottleneck issue in the rapid advancement of energy storage device technologies. [1] The energy harvesting approaches have witnessed several innovations in design and development in the process to attain miniaturization of devices with enhanced output efficiency. The concept of energy harvesting has its history in technological revolution with electromagnetic induction being an ideal concept in converting mechanical energy into electrical energy. [2,3] The incessant consumption of fossil fuels has led the technologists to ponder about alternate resources in energy consumption to develop distributed power supply and portable electronic devices with superior output performances. This led to the invention of triboelectric nanogenerators (TENGs) by Professor Z.L. Wang in 2012. [4] TENG is so far considered as the best option to harvest mechanical energy to consumable electrical energy for sensing and energy storage devices. TENG works on the combination of electrostatic induction and triboelectric effect. TENG enables the possibility to convert mechanical energy into electrical energy with the help of coupling effect between the electrostatic induction and contact electrification between the triboelectric materials, possessing different tendencies to gain or lose electrons. [5] This novel approach to harvest mechanical energy has the tendency to provide electricity for portable electronics and distributed power systems such as physiological monitoring, robotic systems, motion tracking, etc. The performance of TENG devices and TENG sensors has improved dramatically in the few years after its initial publication. [6][7][8] The friction effect is critical to the TENG's output performance, and altering the inner structure is the simplest and most cost-effective technique to increase the contact area without replacing the entire material. The variety of materials available for TENG production is huge, necessitating extensive study ahead of time to achieve the optimum results. [9] The proper selection of materials is vital for enhancing the triboelectric output of the TENG device. There are many techniques to fabricate triboelectric materials which include electrospinning, spin coating, etching, and 3D printing (3DP). [10] 3DP technology has emerged as a promising fabrication method for TENG development due to its fast production time, low-cost modeling, and simplicity of developing sophisticated and tailored structures with excellent material utilization efficiency. [11] The amalgamation of TENGs and 3DP has contributed to the encouragement of new-era energy harvesting technologies and self-powered sensing by making full use of their individual merits. The demerits of 3D printing (3DP) having lesser manufacturing precision than photoetching can be fulfilled by speedy layer-by-layer production of the complicated
