“…Besides shoes and insoles, walking sticks, which serve as mobility aids for the elderly and those with limited motion, can improve the quality of their daily lives by enhancing their walking patterns, balance, and safety [ 70 ]. In addition to these fundamental functions, walking sticks, when combined with advanced wearable electronics, also have the potential to evolve into monitoring platforms, offering users more comprehensive and intelligent assistance [ 71 ]. Guo et al [ 43 ] designed an AI-enabled caregiving walking stick equipped with intelligent monitoring features, and this device serves as a healthcare platform specifically tailored for the elderly and individuals with impaired mobility.…”

With the improvement in life quality, the increased focus on health has expedited the rapid development of portable preventative-health-monitoring devices. As one of the most attractive sensing technologies, triboelectric nanogenerators (TENGs) are playing a more and more important role in wearable electronics, machinery condition monitoring, and Internet of Things (IoT) sensors. TENGs possess many advantages, such as ease of fabrication, cost-effectiveness, flexibility, material-selection variety, and the ability to collect low-frequency motion, offering a novel way to achieve health monitoring for human beings in various aspects. In this short review, we initially present the working modes of TENGs based on their applications in health monitoring. Subsequently, the applications of TENG-based preventive health monitoring are demonstrated for different abnormal conditions of human beings, including fall-down detection, respiration monitoring, fatigue monitoring, and arterial pulse monitoring for cardiovascular disease. Finally, the discussion summarizes the current limitations and future perspectives. This short review encapsulates the latest and most influential works on preventive health monitoring utilizing the triboelectric effect for human beings and provides hints and evidence for future research trends.

“…As presented in Figure 4i and Table S1 (Supporting Information), the d/S ratio of the SNC-TENG can reach 6.25, which is the highest among previously reported noncontact TENGs, further indicating its outstanding noncontact sensing performance. [29][30][31][32][33][34][35][36][37][38][39][40][41] The influences of the ambient temperature and relative humidity on the output of the SNC-TENG were also investigated. As shown in Figures S18 and S19 (Supporting Information), customized experimental setups were constructed, wherein a blower heater and a humidifier were used to control the ambient temperature and the relative humidity, respectively.…”

“…[21][22][23][24][25][26][27][28] Importantly, TENGs are able to function in noncontact scenarios. [29][30][31][32][33][34][35][36][37][38][39][40][41] Since friction with other objects or with the air imparts most daily objects with a surface electrostatic charge, [39] noncontact TENGs can perceive the charged objects with no requirement for physical contact. As such, the working principle of the noncontact TENGs differs from those of the radar and LiDAR technologies; the sensing performances of noncontact TENGs have therefore received growing research attention in recent years.…”

With the ongoing advancement in sensor technologies, the development of intelligent, secure, and low‐carbon vehicles will be possible in the near future. However, providing continuous power to numerous onboard sensors consumes substantial amounts of power from vehicle, resulting in the shortened running times. Herein, a self‐powered noncontact triboelectric nanogenerator (SNC‐TENG) with ultralong‐distance detection and a high sensitivity is proposed, which can be used as ambient perception sensors for smart vehicles. The SNC‐TENG is constructed from a MXene/silicone nanocomposite with a fully embedded conductive sponge, which significantly enriches the tribo‐charges and leads to an excellent capability and performance. This SNC‐TENG is capable of perceiving human activity from a distance of 2 m. To the best of authors knowledge, the perceiving distance per unit area of this SNC‐TENG is the highest among previously reported non‐contact TENGs. Furthermore, the applicability of the SNC‐TENG is explored for vehicle sentry mode and blind spot detection for the first time. The use of this technology in a real vehicle demonstrates its feasibility for use in practical applications. Overall, this study provides a new design scheme for contactless self‐powered sensors, and the presented SNC‐TENG is expected to be applicable in various fields where non‐contact sensing is required.

Tactile sensors with visible light feedback functions, such as wearable displays and electronic skin and biomedical devices, are becoming increasingly important in various fields. However, existing methods cannot meet the application requirements for the tactile perception of intensity feedback and extended intersection due to their limited light‐mapping performance and insufficient portability. Herein, a freely constructible self‐powered visual tactile sensor is proposed, which consists of a high‐output triboelectric nanogenerator (TENG) and a visual light source. The transferred charge of the TENG is enhanced to 746 nC by the structural design of the triboelectric material and device, which can easily drive the light source to generate a light signal with a brightness of 9.8 cd m−2. Notably, the application of the TENG enables to realization visual sensing of the palm‐grasp state and strength feedback without an external power supply. This visual feedback and power‐free tactile sensors are expected to have potential application in the field of artificial intelligence as a new interactive medium for smart protective clothing and robotics.
