| 1 | A static-dynamic energy harvester for a self-powered ocean environment monitoring application显示文摘Ocean intelligent buoy is important for ocean environment monitoring.With the increase of requisite sensors and transportable data,a long power supply has become a problem to be solved urgently.In this work,a hybrid nanogenerator integrating triboelectric,piezoelectric,electromagnetic,photovoltaic,and thermotropic units is proposed to maximize ocean ambient energy harvesting,which includes static energy(solar and thermal energy)and dynamic energy(wave energy).Compared with a device with a single energy conversion mechanism,this structural design breaks the limit of harvesting time and natural conditions during the energy harvesting process,thereby increasing the harvested energy.Static energy harvesting is realized by the thermoelectric(TG)and photovoltaic(PV)units located inside the device and the PV unit attached to the device surface.Results show that the maximum open-circuit voltage and short-circuit current are 5 V and 41 mA in the external PV and 1.33 V and 49 mA in the internal PV under 30000 Lux illumination,respectively.The open-circuit voltage and short-circuit current of the TG unit are 5 V and 15 m A,respectively.The core component of the dynamic generation unit is the gimbal used to harvest wave energy by the triboelectric nanogenerator(TENG),piezoelectric generator(PENG),and electromagnetic generator.When the frequency is 2.4 Hz,the maximum peak-to-peak power of the TENG,PENG,and EMG are 0.25,1.58,and 13.8 mW,respectively.Finally,an intelligent ocean buoy is fabricated by the integration of an energy harvester,a power management circuit,sensors,a microcontroller,and a wireless communication module.Driven by static and dynamic energy,temperature signal,humidity signal,GPS signal,and sound signal are sent to the receiving terminal wirelessly.The ocean energy harvester proposed in this work is of great significance for ocean energy harvesting and ocean wireless monitoring systems. | XUE Feng CHEN Liang LI ChunCheng REN Jing YU JunBin HOU XiaoJuan GENG WenPing MU JiLiang HE Jian CHOU XiuJian | 2022 | Science China(Technological Sciences)2022，65，4： | 2 |

| 5 | Reliability Assessment of a New General Matching Composed Network显示文摘The reliability of a network is an important indicator for maintaining communication and ensuring its stable operation. Therefore, the assessment of reliability in underlying interconnection networks has become an increasingly important research issue. However, at present, the reliability assessment of many interconnected networks is not yet accurate,which inevitably weakens their fault tolerance and diagnostic capabilities. To improve network reliability,researchers have proposed various methods and strategies for precise assessment. This paper introduces a novel family of interconnection networks called general matching composed networks(gMCNs), which is based on the common characteristics of network topology structure. After analyzing the topological properties of gMCNs, we establish a relationship between super connectivity and conditional diagnosability of gMCNs. Furthermore, we assess the reliability of g MCNs, and determine the conditional diagnosability of many interconnection networks. | Zhengyuan Liang Junbin Liang Guoxuan Zhong | 2024 | China Communications2024，21，2： | 0 |
| 6 | Stretchable and skin-conformal piezo-triboelectric pressure sensor for human joint bending motion monitoring显示文摘Stretchable,skin-conformal,and self-powered wearable pressure sensors have garnered significant attention for use in human joint bending motion monitoring.Here,a piezo-triboelectric pressure sensor(P-TPS)based on triboelectric nanogenerator and piezoelectric nanogenerator is demonstrated.The P-TPS can generate an enhanced electrical output by coupling the dual-mode triboelectrification and piezoelectric effect.The P-TPS shows high sensitivity(voltage=0.3 V/kPa;current=4.3 nA/kPa;pres-sure range=0-200 kPa),high linearity,and good stability.Furthermore,it demonstrates a wide mea-surement range(0-800 kPa),table frequency response,and fast response time.Additionally,all components of the P-TPS are fabricated using flexible and stretchable materials,affording satisfactory stretchability and excellent skin conformality.Owing to their ability to self-power,they can be attached to the outside of joints to monitor human joint bending movements in real time.Hence,this study provides a novel method of using a stretchable and skin-conformal piezo-triboelectric nanogenerator with high electrical performance as a self-powered pressure sensor,which offers significant potential in personalized recognition,medical research,and human machine interface. | Junbin Yu Liang Chen Xiaojuan Hou Jiliang Mu Jian He Wenping Geng Xiaojun Qiao Xiujian Chou | 2022 | Journal of Materiomics2022，8，2： | 0 |
