“…During this process, the strong binding affinity between catechin and the TiO 2 nanosheet arrays reduces the work function, thus increasing the transferred charge during contact electrification and final electrical output. [ 123 ] Consequently, the detection of different concentrations of catechin in green tea solution was realized.…”

The rapid advances in the Internet of things and wearable devices have created a massive platform for sensor systems that detect chemical or biological agents. The accelerated development of these devices in recent years has simultaneously aggravated the power supply problems. Triboelectric nanogenerators (TENGs) represent a thriving renewable energy technology with the potential to revolutionize this field. In this review, the significance of TENG‐based sensor systems in chemical or biological detection from the perspective of the development of power supply for biochemical sensors is discussed. Further, a range of TENGs are classified according to their roles as power supplies and/or self‐powered active sensors. The TENG powered sensor systems are further discussed on the basis of their framework and applications. The working principles and structures of different TENG‐based self‐powered active sensors are presented, along with the classification of the sensors based on these factors. In addition, some representative applications are introduced, and the corresponding challenges are discussed. Finally, some perspectives for the future innovations of TENG‐based sensor systems for chemical/biological detection are discussed.

“…[ 145 ] Therefore, solid–liquid interface TENGs are proposed. [ 63,67,68,146–153 ] When liquids are directly used as friction units, the working principle is the freestanding triboelectric‐layer mode shown in Figure 2b. Through continuous contact and separation between surfaces of liquid and solid materials, and a flow of electrons in an external circuit is realized.…”

Ocean contain abundant clean energies including tidal and wave, but such energies are known for low frequency and large excitation amplitude, posing considerable challenges for high‐efficiency energy conversion. As an emerging technology, triboelectric nanogenerators (TENGs) have been widely used in energy harvesting and novel sensor design due to their high sensitivity and flexible structure. Meanwhile, they show great advantages in the low‐frequency environment (<5 Hz), and display great potential for deployment in remote ocean waters, and construction of large‐scale TENG networks. In this review, firstly, the working principle of TENGs and various configurations developed for the marine environment are introduced, which mainly include solid–solid and solid–liquid interfaces. Then, from the viewpoint of power improvement, authors are most concerned about the modification methods of materials such as surface modification, electron injection, and chemical doping. Meanwhile, improved technologies for energy harvesters in marine environment are discussed in detail, such as improving the hydrophobicity and degradation of materials, studying the self‐healing ability of materials, and designing power management circuits. Finally, the current challenges are summarized, and research trends are given from both short‐term and long‐term perspectives.

“…[ 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.
