“…[ 16 ] In the near future, on average, each person will carry dozens of such small electronic devices, which will require a portable power source. [ 17–34 ] The most traditional approach of powering these electronics is to use batteries, which is very likely to face several future issues: [ 35–52 ] 1) The limited and uncertain lifetime of batteries has become a major problem; 2) the end‐of‐life disposal of the hazardous chemicals present in used batteries is becoming a key issue; (3) recycling of the ever‐growing number of batteries has become an arduous and costly task; 4) overcharging of small batteries increases battery flammability; and 5) the larger size of batteries makes electronic devices or sensors bulky, which is problematic for nanodevices/systems. Therefore, for powering small electronic devices or sensors anytime and anywhere, nanogenerators, [ 53 ] also known as energy harvesters, have been proposed.…”

Triboelectric nanogenerator (TENG) development is undergoing rapid progress utilizing the state‐of‐the‐art 3D‐printing technologies. Herein a critical analysis of the latest developments in 3D‐printed wearable and implantable TENGs that can be used to energize small portable electronic and biomedical devices is presented. Recent progress in 3D‐printed triboelectric nanogenerator (3DP‐TENG) materials and architectural formations, as well as their performance, is evaluated for powering systems that implement physiological monitoring, multifunctional sensing, electronic energizing, noise canceling, dust filtering, and self‐healing. Furthermore, the review explicitly focuses on the 3D‐printing approaches used to form stable and robust 3DP‐TENGs. In addition, the key challenges to improving the performance of 3DP‐TENGs for optimal energy harvesting are discussed, and a roadmap is given for research and translation to commercial markets in the next decade.

“…However, this contact area has nanoscale interfaces that determine the final impact on the TENG’s properties. [ 12–38 ] The separation of these materials induces a dipole moment, which drives the charge (e.g., electrons) transfer by applying an external load onto the nanostructured interfaces of the two triboelectric materials. A TENG as a charge‐pump device could also provide current flow back and forth between the electrodes with a specific frequency to produce an alternating current (AC).…”

To meet the future need for clean and sustainable energies, there has been considerable interest in the development of triboelectric nanogenerators (TENGs) that scavenge waste mechanical energies. The performance of a TENG at the macroscale is determined by the multifaceted role of surface and interface properties at the nanoscale, whose understanding is critical for the future development of TENGs. Therefore, various protocols from the atomic to the macrolevel for fabrication and tuning of surfaces and interfaces are required to obtain the desired TENG performance. These protocols branch out into three categories: chemical engineering, physical engineering, and structural engineering. Chemical engineering is an affordable and optimal strategy for introducing more surface polarities and higher work functions for the improvement of charge transfer. Physical engineering includes the utilization of surface morphology control, and interlayer interactions, which can enhance the active interfacial area and electron transfer capacity. Structural engineering at the macroscale, which includes device and electrode design/modifications has a considerable effect on the performance of TENGs. Future challenges and promising research directions related to the construction of next‐generation TENG devices, taking into consideration “interfaces” are also presented.

“…In regard of this, self‐driven sensors have been developed to convert the mechanical driving force into pulsed voltage signals, by analyzing the output electrical signals; information such as the pressure and frequency of the external driving force is obtained without external power sources. This technology has been applied to electronic skins, touch sensing,[3b,12] and other aspects nowadays …”

“…According to the triboelectric series, the negative triboelectric layers such as polydimethylsiloxane (PDMS), polyvinylidene fluoride, or polytetrafluoroethylene are widely used through spin coating, electrospinning, and other methods, because of their strong tendency to gain electrons,[6c,12,23] and this strong ability to get electrons is due to the rich —F groups . The positive triboelectric layers of polyamide, polyester and metal et al,[11a,25] are also widely used due to its ability to lose electrons or miss electrons, this basic knowledge is supported by many related investigations.…”

Flexible self‐driven sensors can respond to tiny vibrations such as sound waves, blood pressure, heartbeat, etc., and have attracted great attention for their promising applications in wearable devices, in which the electrical signals are triggered by mechanical strength and the coupling of triboelectric and electrostatic induction. Herein, flexible self‐driven sensors assembled with a chitosan (CS) film and polydimethylsiloxane (PDMS) film selected as positive and negative triboelectric layers, respectively, are presented. Conductive fabrics function as electrodes, and polyurethane (PU) foams function as flexible substrates which have advantages of simple integrated structures, ease of manufacturing, and relatively low costs. Tests confirm that the sensor has outstanding flexibility, excellent response performance, and remarkable stability. It is used for real‐time monitoring of human movements, and is based on textiles, providing wearing comfort and is operated without any external power sources as the output voltage of about 30 V can support it. Owing to these advantages, it is believed that a new and convenient strategy to fabricate a novel sensor based on available materials used for human activity detecting and healthcare monitoring is achieved.
