2Force-induced charge carrier storage:a new route for stress recording显示文摘Stress sensing is the basis of human-machine interface,biomedical engineering,and mechanical structure detection systems.Stress sensing based on mechanoluminescence(ML)shows significant advantages of distributed detection and remote response to mechanical stimuli and is thus expected to be a key technology of next-generation tactile sensors and stress recorders.However,the instantaneous photon emission in ML materials generally requires real-time recording with a photodetector,thus limiting their application fields to real-time stress sensing.In this paper,we report a force-induced charge carrier storage(FICS)effect in deep-trap ML materials,which enables storage of the applied mechanical energy in deep traps and then release of the stored energy as photon emission under thermal stimulation.The FICS effect was confirmed in five ML materials with piezoelectric structures,efficient emission centres and deep trap distributions,and its mechanism was investigated through detailed spectroscopic characterizations.Furthermore,we demonstrated three applications of the FICS effect in electronic signature recording,falling point monitoring and vehicle collision recording,which exhibited outstanding advantages of distributed recording,longterm storage,and no need for a continuous power supply.The FICS effect reported in this paper provides not only a breakthrough for ML materials in the field of stress recording but also a new idea for developing mechanical energy storage and conversion systems.Yixi Zhuang Dong Tu Changjian Chen Le Wang Hongwu Zhang Hao Xue Conghui Yuan Guorong Chen Caofeng Pan Lizong Dai Rong-Jun Xie 2020Light(Science & Applications)2020,9,1:10

5Real-time pressure mapping smart insole system based on a controllable vertical pore dielectric layer显示文摘Real-time monitoring of plantar pressure has significant applications in wearable biosensors,sports injury detection,and early diagnostics.Herein,an all-in-one insole composed of 24 capacitive pressure sensors(CPSs)with vertical pores in an elastic dielectric layer is fabricated by laser cutting.Optimized CPSs with a hexagonal configuration and a pore size of 600μm possess good linearity over a wide detection range of 0–200 kPa with a sensitivity of 12×10^(–3) kPa−1.Then,a smart system including the all-in-one insole with the 24 CPS array,a data acquisition system with a wireless transmitter and a PC terminal with a wireless receiver is established for real-time monitoring to realize static and dynamic plantar pressure mapping.Based on this smart insole system,various standing and yoga postures can be distinguished,and variations in the center of gravity during walking can be recognized.This intelligent insole system provides great feasible supervision for health surveillance,injury prevention,and athlete training.Juan Tao Ming Dong Li Li Chunfeng Wang Jing Li Yue Liu Rongrong Bao Caofeng Pan 2020Microsystems & Nanoengineering2020,6,1:6
6Investigating the interlayer electron transport and its in?uence on the whole electric properties of black phosphorus显示文摘Two-dimensional(2D) nanomaterials have attracted great attention in next generation electronic and optoelectronic technologies due to the unique layered structure and excellent physical and chemical properties. However, the mechanism of transmission along the vertical direction of 2D semiconductor materials has not been investigated. Here, we use first-principles calculations to explore the bandgap energies along different directions, and fabricate a vertical, a lateral and a mixture-structured black phosphorus field effect transistor(BPFET) to study the electrical characteristics along different directions under variable temperatures. The variable temperature test indicates that the mixture-structured device performs more like a lateral device, while the conductance along the vertical direction is hard to be tuned by temperature and electrical field. The unchanged conductance under electric field and variable temperatures allows the vertical device to act as a fixed resistor, promising possible application for the prospective electronic and optoelectronic devices.Bensong Wan Shaoqiang Guo Jiacheng Sun Yufei Zhang Yuyan Wang Caofeng Pan Junying Zhang 2019Science Bulletin2019,64,4:3

8Controlled fabrication, lasing behavior and excitonic recombination dynamics in single crystal CH3NH3PbBr3 perovskite cuboids显示文摘As a direct bandgap semiconductor, organic-inorganic lead halide perovskite (MAPbX3, MA = CH3NH3, X =Cl, Br, I) have been considered as promising materials for laser due to their excellent optoelectronic properties. The perovskite materials with ID and 2D shapes were widely prepared and studied for Fabry-Perot mode and whispering-gallery-mode (WGM) microcavities, but cuboid-shape is rarely reported. In this work, we successfully fabricated single crystal cuboid-shaped MAPbBr3 perovskite w让h different morphologies, named microcuboid-MAPbBr3 (M-MAPbBr3) and multi-step-MAPbBr3 (MSMAPbBr3), via solvothermal method. Furthermore, the as-prepared *crystals excitonic recombination lifetime under different pumping energy density was studied by time-resolved photoiuminescence (TRPL). Based on controllable morphology and remarkable lasing properties, these cuboid shaped single crystal perovskite could be a promising candidate for small laser, and other optoelectronic devices.Fangtao Li Junfeng Lu Qinglin Zhang Dengfeng Peng Zheng Yang Qian Xu Caofeng Pan Anlian Pan Tianfeng Li Rongming Wang 2019Science Bulletin2019,64,10:2

10Flexible Ag Microparticle/MXene-Based Film for Energy Harvesting显示文摘Ultra-thin flexible films have attracted wide attention because of their excellent ductility and potential versatility.In particular,the energy-harvesting films(EHFs)have become a research hotspot because of the indispensability of power source in various devices.However,the design and fabrication of such films that can capture or transform di erent types of energy from environments for multiple usages remains a challenge.Herein,the multifunctional flexible EHFs with e ective electro-/photo-thermal abilities are proposed by successive spraying Ag microparticles and MXene suspension between on waterborne polyurethane films,supplemented by a hot-pressing.The optimal coherent film exhibits a high electrical conductivity(1.17×10^(4)S m^(-1)),excellent Joule heating performance(121.3℃)at 2 V,and outstanding photo-thermal performance(66.2℃ within 70 s under 100 mW cm^(-1)).In addition,the EHFs-based single-electrode triboelectric nanogenerators(TENG)give short-circuit transferred charge of 38.9 nC,open circuit voltage of 114.7 V,and short circuit current of 0.82μA.More interestingly,the output voltage of TENG can be further increased via constructing the double triboelectrification layers.The comprehensive ability for harvesting various energies of the EHFs promises their potential to satisfy the corresponding requirements.Yunpeng Jia Yamin Pan Chunfeng Wang Chuntai Liu Changyu Shen Caofeng Pan Zhanhu Guo Xianhu Liu 2021Nano-Micro Letters2021,13,12:1
11Mechanoluminescent hybrids from a natural resource for energy-related applications显示文摘Mechanoluminescent(ML)materials that directly convert mechanical energy into photon emission have emerged as promising candidates for various applications.Despite the recent advances in the development of both novel and conventional ML materials,the limited access to ML materials that simultaneously have the attributes of high brightness,low cost,self-recovery,and stability,and the lack of appropriate designs for constructing ML devices represent significant challenges that remain to be addressed to boost the practical application of ML materials.Herein,ML hybrids derived from a natural source,waste eggshell,with the aforementioned attributes are demonstrated.The introduction of the eggshell not only enables the preparation of the hybrid in a simple and cost-effective manner but also contributes to the homochromatism(red,green,or blue emission),high brightness,and robustness of the resultant ML hybrids.The significant properties of the ML hybrids,together with the proposed structural design,such as porosity or core–shell structure,could expedite a series of mechanic-optical applications,including the self-luminous shoes for the conversion of human motions into light and light generators that efficiently harvest water wave energy.The fascinating properties,versatile designs,and the efficient protocol of“turning waste into treasure”of the ML hybrids represent significant advances in ML materials,promising a leap to the practical applications of this flouring material family.Chunfeng Wang Ronghua Ma Dengfeng Peng Xianhu Liu Jing Li Boru Jin Aixian Shan Yu Fu Lin Dong Wenchao Gao Zhong Lin Wang Caofeng Pan 2021InfoMat2021,3,11:1

20Controlled on-chip fabrication of large-scale perovskite single crystal arrays for high-performance laser and photodetector integration显示文摘Metal halide perovskites possess intriguing optoelectronic properties,however,the lack of precise control of on-chip fabrication of the large-scale perovskite single crystal arrays restricts its application in integrated devices.Here,we report a space confinement and antisolvent-assisted crystallization method for the homogeneous perovskite single crystal arrays spanning 100 square centimeter areas.This method enables precise control over the crystal arrays,including different array shapes and resolutions with less than 10%-pixel position variation,tunable pixel dimensions from 2 to 8 pm as well as the in-plane rotation of each pixel.The crystal pixel could serve as a high-quality whispering gallery mode(WGM)microcavity with a quality factor of 2915 and a threshold of 4.14μJ cm^(-2).Through directly on-chip fabrication on the patterned electrodes,a vertical structured photodetector array is demonstrated with stable photoswitching behavior and the capability to image the input patterns,indicating the potential application in the integrated systems of this method.Zhangsheng Xu Xun Han Wenqiang Wu Fangtao Li Ru Wang Hui Lu Qiuchun Lu Binghui Ge Ningyan Cheng Xiaoyi Li Guangjie Yao Hao Hong Kaihui Liu Caofeng Pan 2023Light(Science & Applications)2023,12,4:0
