The TENG sensors have been applied in monitoring rotating speed and angle on many occasions, such as steering wheels [36] and downhole turbodrills [28]. With the rotational motion of the host, the sensors will generate electric pulses.…”

“…Through the sensing of rotating speed, the application of TENG as a selfpowered sensor for the velocity of water flow detection is developed [111]. The sensing of the rotating angle could be realized with interdigital electrodes [36,112] or patterned electrodes [79]. Choi proposed an angle sensor, which contains two interdigitated electrodes and each electrode contains 12 comb fingers (Figure 15c) [36], which will produce 24 signal peaks, each representing 15° (=360°/24), in each circle of rotation.…”

Under the trend of the rapid development of the internet of things (IoT), sensing for dynamic behaviors is widely needed in many fields such as traffic management, industrial production, medical treatment, building health monitoring, etc. Due to the feature of power supply independence and excellent working performance under a low-frequency environment, triboelectric nanogenerators (TENGs) as sensors are attracting more and more attention. In this paper, a comprehensive review focusing on the recent advance of TENGs as sensors for dynamic behaviors is conducted. The structure and material are two major factors affecting the performance of sensors. Different structure designs are proposed to make the sensor suitable for different sensing occasions and improve the working performance of the sensors. As for materials, new materials with stronger abilities to gain or lose electrons are fabricated to obtain higher surface charge density. Improving the surface roughness of material by surface engineering techniques is another strategy to improve the output performance of TENG. Based on the advancement of TENG structures and materials, plenty of applications of TENG-based sensors have been developed such as city traffic management, human–computer interaction, health monitoring of infrastructure, etc. It is believed that TENG-based sensors will be gradually commercialized and become the mainstream sensors for dynamic sensing.

“…[42][43][44] The contact-separation triboelectric mode sensing is usually implemented by pressure or tactile motions. [45][46][47][48][49][50][51][52][53] For example, based on the Ag-nanofiber electrodes patterning and device design, an 8 × 8 array flexible TENG tactile interface is proposed for identification and tactile mapping with rapid response, which has widespread potential in tactile sensing and touchpad technology applications. [54] On the other hand, the lateral-sliding mode triboelectric sensing is generally realized through the pressure/tactile sensor array or strip electrodes along the trace.…”

in diverse application fields, for example, entertainment, robotics, [3] virtual reality/ augmented reality (VR/AR), [4] smart factory, and so on. [5-7] Beyond that, HMI can even be extended to medical rehabilitation, [8] extreme environmental operation, [9] remote education, telemedicine, and other fields. [10,11] With the aid of technology advance, the effectiveness and intuitiveness of interaction are more demanding. The solutions of HMI are switching from the conventional control terminals, such as keyboard, touchpad, and joystick, toward more diversified and creative alternatives. As a result, many new interaction mechanisms have been developed to satisfy the need for efficient and intuitive interaction. [12] For instance, vision recognition can identify facial features and realize human motion capture to complete motion mapping. [13,14] Evolving together with the fast-growth of wearable electronics and IoT, modern HMI are developing toward self-powered capability [15-17] and flexible wearable compatibility. [12] Self-powered electronics are of increasing importance due to their environmentally friendly and self-sustainability, providing an possible solution in alleviating the global energy crisis and environmental pollution. [18-22] Many self-powered electronics have been developed by integrating different energy harvesting technologies, such as electromagnetic, [18-20] piezoelectric, [21,22] and triboelectric. [17,18,23-26]. Based on the coupling of triboelectrification and electrostatic induction, triboelectric nanogenerators (TENGs) have been demonstrated as promising candidates [27-33] for various selfpowered sensing or self-driven controlling [16,17,25] applications. For example, Luo reported a flexible and durable wood-based TENG for self-powered sensing in athletic big data analytics. [34] It can be used to smart sport monitoring and assisting. It also can be used to promote the development of big data analytics in intelligent sports industry. TENG-based self-powered technology provides a creative way to realize HMI [35,36] because of its superior advantages such as self-generated signals, high output sensitivity, simple but diverse configurations, low cost, various material applicability, and flexibility. [34,37,38] In the past few years, there have been many HMI prototypes reported by using triboelectric mechanisms. [16,25,31,35,39-41] In recent years, human-machine interface technology has entered a period of rapid development in the global scope. It has gradually expanded from the initial field of medical rehabilitation to engineering bionics, virtual reality, space technology, deep-sea assignments, atomic energy technology, remote education, and other areas. Herein, an innovative, self-powered delta-parallel human-machine interface (DT-HMI) for 3D sensing and control is proposed. By using three pairs of triboelectric nanogenerator (TENG) sensing gears based on both contact-separation and sliding modes of triboelectric effect, the positive and negative rotation of the gears and rotation angles ca...

“…[8,9] Nowadays, there are mainly three types of gyroscope sensors, namely mechanical, optical fiber, and microelectromechanical system (MEMS) gyroscopes, providing information on motion variables such as acceleration, angle, tilt, and angular velocity. [10,11] Although these gyroscopes have been employed in multiple scenarios in the air, ground, ocean, and space, an external power source is required for the energy supply, which suffers weak battery endurance. The gyroscopes could not operate continuously, since batteries are obliged to be substituted or recharged frequently.…”

Progressive improvements of the Internet of Things (IoT) promote the sustainable development of the modern information society. [1,2] When the IoT is an analogy to the human sense as a means to immediately acquire precise environmental information, the large-scale and widely distributed sensor networks are similar to synaptic terminals, which are available to accurately realize various functions of intelligent identification, positioning, tracking, monitoring, and management. Among them, motion sensors, such as accelerometer, tilt sensor, vibration sensor, and rotation sensor, are widely utilized in health care, civil defense, industrial production, and home security. [3][4][5] Gyroscope is one of the most widely used motion sensors, which is dependent on the inertia to make the rotating shaft of the gyroscope rotor maintain a fixed direction under high-speed rotating motion and simultaneously measure the angular movement. [6,7] After incorporating the signal processing circuit, the gyroscope could not only realize the artificial intelligence health monitoring, for example, evaluating the patient's exercise ability after treatment, analyzing and testing the training performance of the athletes but also be applied to military automatic control systems, for instance, monitoring the flying posture of drones and taking photos, detecting the trajectory of space shuttles, trains, and ships, and locating the precise positions of mine tunnels, missile silos, and oil base. [8,9] Nowadays, there are mainly three types of gyroscope sensors, namely mechanical, optical fiber, and microelectromechanical system (MEMS) gyroscopes, providing information on motion variables such as acceleration, angle, tilt, and angular velocity. [10,11] Although these gyroscopes have been employed in multiple scenarios in the air, ground, ocean, and space, an external power source is required for the energy supply, which suffers weak battery endurance. The gyroscopes could not operate continuously, since batteries are obliged to be substituted or recharged frequently. However, it is difficult to replace the battery under extreme weather and unique environments. Moreover, the enormous power supply system induces severe challenges to manufacturing the sensor networks for IoT in mass production.Ubiquitous mechanical movements such as wind, tide, vibration, and human body motion could be exploited as a
