Description
技术领域
本发明涉及传感器领域,特别是涉及湿度传感器领域。
背景技术
多模态检测和复合传感是未来传感器发展的重要方向。现代工业设备内部狭小层间的间隙关乎设备的性能和安全,因而有间隙检测的需求。同时,现代工业设备内部的湿度较高可能会引起设备生锈和短路,因而有湿度检测的需求。所以,如何实现现代工业设备内部的间隙和湿度两个变量的同时检测是亟需解决的问题。传统的非接触式间隙敏感元件的探头敏感层材料一般由金属制成,不具备湿度敏感功能。而传统的湿度传感器是在叉指电极上涂覆敏感材料呈三明治结构,不具备非接触间隙敏感功能。所以两个变量同时检测需要分别安装两个传感器,这样的方案存在局限。一方面,面对不同测量需求,需要频繁切换不同敏感元件较为繁琐;另外一方面,面对多变量同时测量需求,需要安装多个敏感元件分别测量,成本较高且安装环境受限。尤其在狭小的被测环境,内部结构复杂,难以实现多敏感元件的同时安装和同时检测。所以研究一种能够同时测量湿度和非接触间隙的单一敏感元件及元件制备方法是非常有必要的。
发明内容
为了解决现有敏感元件功能单一,多功能敏感元件响应分离困难的问题,本发明提供一种分离元件阻抗对湿度和间隙响应的方法,在衬底层上依次镀螺旋式间隙单敏感层、间隙单敏感绝缘层、间隙单敏感电极层、引线层、间隙湿度双敏感绝缘层、间隙湿度双敏感电极层和螺旋式间隙湿度双敏感层得到能够同时响应湿度激励和间隙激励且便于响应分离的单一敏感元件;且所述螺旋式间隙单敏感层和所述螺旋式间隙湿度双敏感层的平面螺旋结构的线宽、线距和匝数均相同;当所述敏感元件被施加间隙激励并通入交流电,所述螺旋式间隙单敏感层产生间隙敏感效应,生成感应磁场改变所述间隙单敏感电极层和所述引线层之间等效阻抗,响应所述间隙激励;同时所述螺旋式间隙湿度双敏感层也产生间隙敏感效应,生成感应磁场改变所述间隙湿度双敏感电极层和所述引线层之间等效阻抗,响应所述间隙激励;而当所述敏感元件被施加湿度激励,所述螺旋式间隙单敏感层不响应湿度激励,仅螺旋式间隙湿度双敏感层响应湿度激励,吸附水分子改变电导率,进而改变所述间隙湿度双敏感电极层和所述引线层之间等效阻抗;当敏感元件被同时施加湿度激励和间隙激励时,所述间隙湿度双敏感电极层和所述引线层之间等效阻抗变化来同时响应湿度激励和间隙激励,而间隙单敏感电极层和所述引线层之间等效阻抗变化仅仅响应间隙激励,所以所述间隙湿度双敏感电极层和所述引线层之间等效阻抗变化量与所述间隙单敏感电极层和所述引线层之间等效阻抗变化量的差值为单一的所述湿度激励引起的敏感元件阻抗响应,从而分离湿度响应和间隙响应。
在其中一个实施例中,所述衬底层材料为陶瓷,所述间隙单敏感绝缘层和所述间隙湿度双敏感绝缘层的材料为Al2O3,所述螺旋式间隙单敏感层和所述螺旋式间隙湿度双敏感层的材料为ZnO;所述引线层、所述间隙敏感电极层和所述间隙湿度双敏感电极层材料为ZnO。
在其中一个实施例中,由于被所述间隙单敏感绝缘层和所述间隙湿度双敏感绝缘层覆盖,所述螺旋式间隙单敏感层隔绝了空气水分子的接触。
在其中一个实施例中,所述在衬底层上依次镀螺旋式间隙单敏感层、间隙单敏感绝缘层、间隙单敏感电极层、引线层、间隙湿度双敏感绝缘层、间隙湿度双敏感电极层和螺旋式间隙湿度双敏感层得到能够同时响应湿度激励和间隙激励且便于响应分离的单一敏感元件;具体为:
(1)将衬底及不锈钢掩膜板置于去离子水、丙酮内超声清洗后,经氮气吹干备用;
(2)磁控溅射制备螺旋式间隙单敏感层;
(3)在所述螺旋式间隙单敏感层上物理气相沉积制备间隙单敏感绝缘层;
(4)在所述间隙单敏感绝缘层上磁控溅射制备所述间隙敏感电极层;
(5)在所述间隙单敏感绝缘层和所述间隙敏感电极层上磁控溅射引线层;
(6)在所述引线层和所述间隙单敏感绝缘层上通过物理气相沉积间隙湿度双敏感绝缘层;
(7)在所述间隙湿度双敏感绝缘层上磁控溅射制备间隙湿度双敏感电极层;
(8)在所述间隙湿度双敏感电极层和所述间隙湿度双敏感绝缘层上磁控溅射制备螺旋式间隙湿度双敏感层;
(9)将步骤(8)所制备的敏感元件退火处理;
从而制备得到呈现双层螺旋结构的便于湿度和间隙响应分离的敏感元件。
在其中一个实施例,间隙湿度双敏感绝缘层和间隙单敏感绝缘层的沉积时间为1个小时以上。
在其中一个实施例,间隙湿度双敏感层和间隙单敏感层的溅射时间相同。
上述分离元件阻抗对湿度和间隙响应的方法的有益效果:
(1)螺旋式间隙湿度双敏感层能够同时响应湿度和间隙激励。
(2)螺旋式间隙单敏感层能够非接触地响应单一间隙激励。
(3)独特的双层螺旋结构便于通过不同引线之间阻抗变化来分离湿度响应和间隙响应。
(4)工艺简单,过程可控,敏感元件灵敏度较高,且通过蒸发镀膜工艺制备绝缘层薄膜确保敏感层之间的绝缘性,通过磁控溅射镀膜工艺制备的间隙敏感电极层、间隙湿度双敏感电极层和引线层材料的一致性,避免引入金属导体,干扰涡流磁场。
