| 1 | Highly stretchable polymer/silver nanowires composite sensor for human health monitoring显示文摘Flexible strain sensors exhibit outstanding advantages in terms of sensitivity and stability by detecting changes in physical signals.It can be easily attached to human skin and clothed to achieve monitoring of human motion and health.However,general sensing material shows low stretchability and cannot respond to signals under large deformation.In this work,a highly stretchable polymer composite was developed by adding small amount(0.17 wt.%)of silver nanowires(AgNWs)in stretchable conductive polymer materials.The conductivity of polymer/AgNWs composite is 1.3 S/m with the stretchability up to 500%.The stretchable strain sensor based on the polymer/AgNWs composite can respond to strain signals in real time,even for 1%strain response,and shows excellent stability over 1,000 loading/unloading cycles.Moreover,the strain sensor can be attached to human skin and clothed to monitor joints,throat and pulse of the human body.The human body electrocardiogram(ECG)signal was detected successfully with the polymer/AgNWs electrode,which is comparable to the signal obtained by the commercial electrode.Overall,the sensors enable monitoring of human movement and health.These advantages make it a potential application in wearable devices and electronic skin. | Yanjing Zhang Pei He Meng Luo Xiaowen Xu Guozhang Dai Junliang Yang | 2020 | Nano Research2020，13，4： | 7 |
| 2 | Formation and Optical Properties of ZnO:ZnFe_(2)O_(4) Superlattice Microwires显示文摘Pure ZnO hexagonal microwires and Fe(Ⅲ)-doped ZnO microwires(MWs)with a novel rectangular cross section were synthesized in a confined chamber by a convenient one-step thermal evaporation method.An oriented attachment mechanism is consistent with a vapor-solid growth process.Photoluminescence(PL)and Raman spectroscopy of the Fe(Ⅲ)-doped ZnO MWs and in situ spectral mappings indicate a quasi-periodic distribution of Fe(Ⅲ)along a one-dimensional(1-D)superlattice ZnO:ZnFe_(2)O_(4) wire,while PL mapping shows the presence of optical multicavities and related multimodes.The PL spectra at room temperature show weak near-edge doublets(376 nm and 383 nm)and a broad band(450-650 nm)composed of strong discrete lines,due to a 1-D photonic crystal structure.Such a 1-D coupled optical cavity material may find many applications in future photonic and spintronic devices. | Yun Li Guozhang Dai Chunjiao Zhou Qinglin Zhang Qiang Wan Limin Fu Jianping Zhang Ruibin Liu Chuanbao Cao Anlian Pan Yunhong Zhang Bingsuo Zou | 2010 | Nano Research2010，3，5： | 2 |
