Liquid leakage of pipeline networks not only results in considerableresource wastage but also leads to environmental pollution and ecological *** response to this global issue, a bioinspired superhydrophobic thermoplastic polyurethane/carbon nanotubes/graphene nanosheets flexible strain sensor (TCGS) hasbeen developed using a combination of micro-extrusion compression molding andsurface modification for real-time wireless detection of liquid leakage. The TCGSutilizes the synergistic effects of Archimedean spiral crack arrays and micropores,which are inspired by the remarkable sensory capabilities of scorpions. This designachieves a sensitivity of 218.13 at a strain of 2%, which is an increase of 4300%. Additionally, it demonstrates exceptional durability bywithstanding over 5000 usage cycles. The robust superhydrophobicity of the TCGS significantly enhances sensitivity and stability indetecting small-scale liquid leakage, enabling precise monitoring of liquid leakage across a wide range of sizes, velocities, and compositionswhile issuing prompt alerts. This provides critical early warnings for both industrial pipelines and potential liquid leakage scenariosin everyday life. The development and utilization of bioinspired ultrasensitive flexible strain sensors offer an innovative and effectivesolution for the early wireless detection of liquid leakage.

目的了解糖尿病患者静态行为的现状及与代谢综合征及其相关组分的关系,为糖尿病患者的有效干预提供措施。方法于2013年12月至2014年1月采用整群抽样的方法,对常熟市10 247例糖尿病患者有关人口学特征、静态行为、疾病史等情况展开问卷调查以及血压、腰围等体格测量和血糖、血脂等实验室检查。用SPSS 17.0软件进行χ2检验、t检验和多因素logistic回归分析。结果常熟市糖尿病患者中代谢综合征检出率为41.4%,高血压检出率为82.6%,血脂异常检出率为44.2%,中心性肥胖检出率为44.2%。糖尿病患者每日平均静态行为时间为(3.36±2.42)h,男性[(3.50±2.35)h]大于女性[(3.26±2.46)h],差异有统计学意义(t=4.98,P<0.01)。24.5%的糖尿病患者每日静态行为时间大于4 h。多元logistic回归结果显示,日均静态行为时间4 h以上与代谢综合征的患病风险相关(OR=1.223,95%CI:1.112~1.346),并增加血脂异常(OR=1.248,95%CI:1.136~1.371)和中心性肥胖的风险(OR=1.249,95%CI:1.136~1.373)。结论糖尿病患者日均静态行为时间较长,日均静态行为时间4 h以上是代谢综合征以及血脂异常和中心性肥胖的危险因素。在糖尿病患者中应提倡改变静态生活方式,减少其他慢性病的发生,改善糖尿病的预后。
