“…Self-powered sensors based on emerging triboelectric nanogenerator technology have been demonstrated to possess promising sensing capabilities with numerous advantages, such as simple structure, high robustness, and low cost (Wang, 2014;Pu et al, 2017;Zhang et al, 2017;Xiao et al, 2021;Zhao et al, 2021;Conta et al, 2021;Peng, 2021;Mahmud et al, 2021;Chen et al, 2016;Yan, 2020;Xu et al, 2020). Such sensors are capable of generating significant electrical signals in response to ambient stimuli without external power supply (Huang et al, 2021;Su et al, 2020a;Tat et al, 2021;Zou et al, 2020;Zou, 2021). Moreover, their output signals can be directly used as sensing signals to reflect the dynamic changes of their sensing elements (Zhang et al, 2021;Su et al, 2020b;Jiang et al, 2020;Wang et al, 2018).…”

“…[ 100 ] In a solid–solid‐interface‐based TENG, the target molecules will change the electron‐transfer‐dominant process resulting in the change of the surface electric potential distribution of the triboelectric material. [ 101,102 ] Similarly, In a liquid–solid‐interface‐based TENG, the target molecules will change the surface electric potential distribution of the triboelectric material as they can influence the formation or structure of the electric double layer. [ 103 ] These effects can lead to changes in output performances, which can be used as sensing signals.…”

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.

“…Respiration, such as chest movement and breathing air‐flow, is a spontaneous, periodical, and uninterrupted mechanical motion of human being that can be employed as a continuous biokinetic energy source to drive low power wearable electronics and integrated body sensor networks. Up to now, piezoelectric effect, [ 59–65 ] triboelectric effect, [ 66–77 ] and thermoelectric effect [ 78–85 ] have been used to scavenge a variety of human biomechanical motions, including walking, [ 86 ] tapping screen, [ 87 ] running, [ 88 ] blood flow, [ 89 ] and breath. [ 90 ] Among them, TENGs provide a number of advantages over other techniques mentioned above, such as being more facile, economical, light weight, and with a diversity of fabricating materials.…”

In mammals, physiological respiration involves respiratory cycles of inhaled and exhaled breaths, which has traditionally been an underutilized resource potentially encompassing a wealth of physiologically relevant information as well as clues to potential diseases. Recently, triboelectric nanogenerators (TENGs) have been widely adopted for self‐powered respiration monitoring owing to their compelling features, such as decent biocompatibility, wearing comfort, low‐cost, and high sensitivity to respiration activities in the aspect of low frequency and slight amplitude body motions. Physiological respiration behaviors and exhaled chemical regents can be precisely and continuously monitored by TENG‐based respiration sensors for personalized health care. This article presents an overview of TENG enabled self‐powered respiration monitoring, with a focus on the working principle, sensing materials, functional structures, and related applications in both physical respiration motion detection and chemical breath analysis. Concepts and approaches for acquisition of physical information associated with respiratory rate and depth are covered in the first part. Then the sensing mechanism, theoretical modeling, and applications related to detection of chemicals released from breathing gases are systemically summarized. Finally, the opportunities and challenges of triboelectric effect enabled self‐powered respiration monitoring are comprehensively discussed and criticized.
