针对偏瘫病患者身体接触面间的压力分布检测,提出并研发了一种基于压阻效应的新型非硅薄膜网格压力传感器。它利用实心柱式压力传感器检测原理,通过丝网印刷工艺制作而成,具有准确、快速、高效、直观、超薄、耐用、可重复使用等特点;总测量厚度为0.32mm。制品测试分析表明该传感器能够快速直观地检测出接触面间的压力分布。同时,新型非硅薄膜网格压力传感器也为生物医疗、康复和汽车等领域提供了新的研究手段。
A new type of non-silicon thin film grid pressure sensor was brought forward and devised to detect and measure the pressure distribution between the bodies's touching surfaces of hemiplegics patient. The sensor was made out by utilizing the detecting principle of solid column pressure sensor and the screen printing typography. The sensor which totally measuring thickness was 0. 32 mm had the following characters: exactly gauging, quickly responding, visually displaying, ultra-thinning, well wearing, and repeatedly reusing. By test and analysis, its result displayed that this sensor could detect out the pressure distribution between touching surfaces quickly and visually. And, the non-silicon thin film grid pressure sensor could supply new studying approaches for the fields of biomedicine, body rehabilitation, and automobile and so on.
