新型智能老年人冲锋衣的研制与性能评价

Development and performance evaluation of new intelligent outdoor jacket for the elderly

为了提高老年人户外运动时运动服的压力舒适性和生理监测的有效性,应用液态氨纶高性能材料和微纳传感元件,采取多开口立体结构,设计研发了老年人新型智能冲锋衣。基于三维虚拟仿真着装试验,通过人体皮肤压力测试服装的舒适性,同时,以真人进行着装试验,采用视觉模拟评分法评价服装血压监测传感工效。试验结果表明:运动过程中,穿着新型智能老年人冲锋衣的压力舒适性显著优于普通老年人冲锋衣,血压监测智能元件输出电平功率在-21 dB,灵敏度在位移1 mm时,血压监测信号频率(RSSI)达到2 400 MHz和2 480 MHz,灵敏度达到最佳,显著提高了老年人户外运动的安全监护性能。

In order to improve the pressure comfort and physiological monitoring effectiveness of the elderly during outdoor healthy exercise,a new intelligent outdoor jacket for the elderly was designed and developed by using liquid spandex high-performance materials and micro nano sensing elements and adopting multi opening three-dimensional structure.Based on the three-dimensional virtual simulation clothing experiment,the comfort of clothing is tested through human skin pressure.At the same time,the visual simulation scoring method is used to evaluate the sensing efficiency of clothing blood pressure monitoring.The results of the experiment showed that during exercise,the pressure comfort of the new intelligent outdoor jacket is significantly better than that of the ordinary outdoor jacket.When the output level power of the intelligent element for blood pressure monitoring is-21 dB,the intelligent sensing sensitivity for blood pressure monitoring is 1 mm.The blood pressure monitoring signal frequency(RSSI)reaches 2400 MHz and 2480 MHz,and the sensitivity reaches the best,which significantly improves the safety monitoring of outdoor sports for the elderly.
