“…Harvesting renewable energy, including but not limited to solar ( Oh et al., 2012 ), wind ( El-Askary et al., 2015 ; Wen et al., 2016 ; Kosunalp, 2017 ; Orrego et al., 2017 ), rain drop ( Zheng et al., 2014 ), and blue energy ( Li et al., 2019 ; Chen et al., 2020 ) from the ambient environment, and then converting it into electricity to provide power supply to IoT applications, is of utmost significance to the sustainable development of modern society. Wind energy is widely known as a kind of renewable energy, which is ubiquitous in the wildness ( Cheng and Zhu, 2014 ; Wang et al., 2016 ; Lai et al., 2019 ), and wind energy harvester (WEH) is considered as an ideal solution to sustainable power supply to smart sensors in IoT applications ( Bethi et al., 2019 ; Wang et al., 2020 ). Generally speaking, the existing WEHs can be divided into two types: vibrational and rotational.…”

Summary This article proposed a high-performance triboelectric-electromagnetic hybrid wind energy harvester (WEH). By adopting the revolution and rotation movements of tapered rollers, which serve as both the rotor of the electromagnetic generator (EMG) part and freestanding layers of the triboelectric nanogenerator (TENG) part, the WEH can work as a sustainable power source and a self-powered wind speed sensor. When the wind speed is 12 m/s, super-high open-circuit voltage peaks of 47.4 and 683 V can be achieved by the EMG and TENG, respectively, corresponding to the high-power outputs of 62 and 1.8 mW. It was demonstrated that the WEH can easily light up over 600 red light-emitting diodes and even a 5-W globe light. A self-powered wireless temperature and humidity sensing network was also systematically demonstrated. In summary, the proposed WEH exhibits bright future toward IoT applications, such as in border detection, smart buildings, and so on.

“…In addition, in order to collect different forms of energy more effectively, hybridized nanogenerators are also developed [ 29 ]. Furthermore, because the output voltage and current signals can represent the various dynamic motions triggered by mechanism, the TENGs can also be employed as a variety of self-powered sensors, such as vibration [ 30 ], wind speed [ 31 ], flow rate [ 32 ], displacement [ 33 ], pressure [ 34 ], tilt [ 35 ], and wave [ 36 ] sensors.…”

With the development of intelligent ship, types of advanced sensors are in great demand for monitoring the work conditions of ship machinery. In the present work, a self-powered and highly accurate vibration sensor based on bouncing-ball triboelectric nanogenerator (BB-TENG) is proposed and investigated. The BB-TENG sensor consists of two copper electrode layers and one 3D-printed frame filled with polytetrafluoroethylene (PTFE) balls. When the sensor is installed on a vibration exciter, the PTFE balls will continuously bounce between the two electrodes, generating a periodically fluctuating electrical signals whose frequency can be easily measured through fast Fourier transform. Experiments have demonstrated that the BB-TENG sensor has a high signal-to-noise ratio of 34.5 dB with mean error less than 0.05% at the vibration frequency of 10 Hz to 50 Hz which covers the most vibration range of the machinery on ship. In addition, the BB-TENG can power 30 LEDs and a temperature sensor by converting vibration energy into electricity. Therefore, the BB-TENG sensor can be utilized as a self-powered and highly accurate vibration sensor for condition monitoring of intelligent ship machinery.
