| 1 | Raindrop energy-powered autonomous wireless hyetometer based on liquid-solid contact electrification显示文摘Triboelectric nanogenerators(TENGs)can directly harvest energy via solid-liquid interface contact electrification,making them very suitable for harvesting raindrop energy and as active rainfall sensors.This technology is promising for realizing a fully self-powered system for autonomous rainfall monitoring combined with energy harvesting/sensing.Here,we report a raindrop energy-powered autonomous rainfall monitoring and wireless transmission system(R-RMS),in which a raindrop-TENG(R-TENG)array simultaneously serves as a raindrop energy harvester and rainfall sensor.At a rainfall intensity of 71 mm/min,the R-TENG array can generate an average short-circuit current,open-circuit voltage,and maximum output power of 15 pA,1800 V,and 325 pW,respectively.The collected energy can be adjusted to act as a stable 2.5 V direct-current source for the whole system by a power management circuit.Meanwhile,the R-TENG array acts as a rainfall sensor,in which the output signal can be monitored and the measured data are wirelessly transmitted.Linder a rainfall intensity of 71 mm/min,the R-RMS can be continuously powered and autonomously transmit rainfall data once every 4 min.This work has paved the way for raindrop energy-powered wireless hyetometers,which have exhibited broad prospects in unattended weather monitoring,field surveys,and the Internet of Things. | Chaoqun Xu Xianpeng Fu Chengyu Li Guoxu Liu Yuyu Gao Youchao Qi Tianzhao Bu Yuanfen Chen Zhong Lin Wang Chi Zhang | 2022 | Microsystems & Nanoengineering2022，8，2： | 2 |
| 2 | Self-powered Internet of Things sensing node based on triboelectric nanogenerator for sustainable environmental monitoring显示文摘The myriad sensing nodes in the Internet of Things(IoT)are mainly powered by battery,which has limited the lifespan and increased the maintenance costs.Herein,a self-powered IoT sensing node based on triboelectric nanogenerator(TENG)is proposed for the sustainable environmental monitoring.The wind powered TENG(W-TENG)is adopted in freestanding mode with the rabbit hair and six pairs of finger electrodes.With the energy management module,the weak electrical energy from WTENG can be converted into a stable direct current(DC)2.5 V voltage for the operation of the IoT sensing node.When the storage energy exceeds 4.4 V,the node can be activated,then the microprogrammed control unit(MCU)transmits the monitoring data.Thereafter,the monitoring data will be identified and relayed to the IoT cloud platform by narrowband IoT(NBIoT)module.At a wind speed of 8.4 m/s,the node can realize the wireless monitoring and data transmission for temperature and atmosphere pressure every 30 s.This work has provided a universal strategy for sustainable IoT sensing nodes powered by environmental micro-nano mechanical energy and exhibited potential applications in IoT,big data,and environmental monitoring. | Yuhan Qin Xianpeng Fu Yuan Lin Zheng Wang Jie Cao Chi Zhang | 2023 | Nano Research2023，16，9： | 0 |
| 3 | Tribotronics: an emerging field by coupling triboelectricity and semiconductors显示文摘Tribotronics is an emerging research field that focuses on the coupling of triboelectricity and semiconductors.In this review,we summarise and explore three branches of tribotronics.Firstly,we introduce the tribovoltaic effect,which involves direct-current power generation through mechanical friction on semiconductor interfaces.This effect offers significant advantages in terms of high power density compared to traditional insulator-based triboelectric nanogenerators.Secondly,we elaborate on triboelectric modulation,which utilises the triboelectric potential on field-effect transistors.This approach enables active mechanosensation and nanoscale tactile perception.Additionally,we present triboelectric management,which aims to improve energy supply efficiency using semiconductor device technology.This strategy provides an effective microenergy solution for sensors and microsystems.For the interactions between triboelectricity and semiconductors,the research of tribotronics has exhibited the electronics of interfacial friction systems,and the triboelectric technology by electronics.This review demonstrates the promising prospects of tribotronics in the development of new functional devices and self-powered microsystems for intelligent manufacturing,robotic sensing,and the industrial Internet of Things. | Chi Zhang Junqing Zhao Zhi Zhang Tianzhao Bu Guoxu Liu Xianpeng Fu | 2023 | International Journal of Extreme Manufacturing2023，5，4： | 0 |
