Fabricating a smart clothing system based on strain-sensing yarn and novel stitching technology for health monitoring

Various yarn-shaped flexible strain sensors have recently been developed.However,research is lacking on additive manufacturing for smart clothing for integrating yarn sensors with commercial garments.Herein,a strain-sensing yarn is sewn into a piece of fabric through a novel stitching technique,and the influence of the stitching method and needle pitch on the sensing performance is investigated using finite element analysis(FEA).The sensing performance could be improved when the sensing yarn is self-locked in the fabric at the needle eyes,and the needle pitch was reduced to 0.5 cm,which is attributed to the enhanced stress and strain concentration.Meanwhile,the composite sensing fabric featured outstanding performance,including a low detection limit(0.1%),rapid response(280 ms),excellent durability(10000 cycles),and high stability(negligible drift and frequency independence).In addition,the remarkable wear resistance,washability,and anti-interference to ambient humidity and perspiration were obtained.Therein,the optimal stitch trace lengths of sensing yarn for detecting elbow motion,breathing,and heartbeats are discussed.Finally,a smart clothing system composed of smart clothing,data acquisition unit,and mobile APP was developed to simultaneously detect human movement and physiological signals.This work provides a reference to produce intelligent garments based on yarn sensors for health monitoring.

Application and Regulation of Legal Science and Technology on the Pilot Program of the Reform of Separation between Complicated Cases and Simple Ones in Civil Procedure in the Basic People’s Courts

Blockchain,artificial intelligence,and other technologies have been increasingly integrated with the law,and the construction of smart justice and Internet courts in various places has a prominent effect on court informatization.The Supreme People’s Court is currently carrying out the pilot reform of separation between complicated and simple cases in civil procedure,and legal technology will inevitably become a major means to enable the reform.In the field of electronic litigation,legal technology itself has become a goal of the reform.Regarding the trials of pilot basic courts,legal technology has been more deeply applied in many links such as trial activities and trial management,playing an essential role in improving judicial efficiency,and becoming an important way to solve judicial dilemmas such as“litigation explosion.”However,the history of modern society reminds us that we should be reasonably optimistic about the development of technology,especially in the field of justice.

典型有机磷阻燃剂对蓝藻的Hormesis效应及机制探究

为探究有机磷阻燃剂(Organophosphate Flame Retardants,OPFRs)对蓝藻的毒性效应,以铜绿微囊藻为蓝藻受试模型,测定典型OPFRs{烷基OPFRs磷酸三乙酯(Triethyl Phosphate,TEP)和氯代OPFRs磷酸三(2-氯乙基)酯[Tris(2-Chloroethyl)Phosphate,TCEP]}对蓝藻生长及光合色素、氧化应激、细胞膜疏水性等相关生理指标的影响。结果显示,TEP与TCEP均对铜绿微囊藻的生长产生了低质量浓度促进、高质量浓度抑制的Hormesis效应,促进生长的质量浓度分别为6.80×10^(-4)~1.53×10^(-1)mg/L和5.87×10^(-5)~1.54×10^(-1)mg/L。相关生理指标变化显示,低质量浓度OPFRs通过提高光合色素的合成及调控活性氧的适当增加可刺激蓝藻增殖;相反,高质量浓度OPFRs则阻碍光合作用,对藻细胞产生氧化胁迫,进而改变细胞膜疏水性致使细胞膜受损,最终导致蓝藻大量死亡。研究结果表明,OPFRs能引发蓝藻生长的Hormesis效应,且氯代OPFRs比烷基OPFRs具有更明显的生物效应,在一定暴露质量浓度内具有促进蓝藻水华形成的潜在环境风险。研究可为OPFRs水生毒性和相应的环境风险评价提供数据基础和理论依据。
