作者陈思琪(2019)在《基于蝎子体表感受器灵敏感知机理的毛缝结合仿生传感器研究》一文中研究指出:在国民经济高速发展,信息化程度不断提升的时代背景下,传感技术作为一个国家发展实力的重要衡量指标,亟待进一步发展。传感器不仅在医疗、环境、军事、工业及农业方面有着广泛应用,在交通、保健、家居等方面也有一定的优越性。在自然界中,生物也存在着各式各样的感知系统,为它们实现外部信息的输入、控制和输出,这与传感器的工作过程不谋而合。现如今仿生科学方兴未艾,生物天然具备的优异感知能力成为传感器研究的丰富灵感来源,各类仿生传感器应运而生,从结构、材料等多个角度对传统传感器进行改良,为传感技术的发展引领了新方向,开拓了新领域,谱写了新篇章。本文结合仿生学基本原则和相关原理,选取了具备超灵敏感知功能的节肢动物——蝎子作为仿生传感器研究模本,通过表征分析其体表感受器:缝感受器和蛊毛感受器的形态结构特征,探析了二者的感知机理;并以之为原型设计了毛缝结合仿生传感元件且进行了相关理论计算和模拟分析;制造了毛缝结合仿生传感器并进行了多领域应用性能测试,为制造超灵敏多功能的仿生传感器做出了新的尝试与探索。本文的主要研究内容及结论如下:首先,按照不同生存环境分类选取典型蝎子样本作为研究生物原型,分别为:黄鳄背蝎(Hottentotta trilineatus)、黑粗尾蝎(Parabuthus transvaalicus)、马氏钳蝎(Buthus martensii)和彼得异蝎(Heterometrus petersii),随后采用体视显微镜、扫描电子显微镜、超薄切片和X射线三维显微镜等多种观测手段,对其缝感受器和蛊毛感受器的表面形态及内部结构进行了表征,发现缝感受器整体由多个缝单元组成,其长度依次递增,宽度基本不变,总体排布呈现放射状;而蛊毛感受器主要由两部分组成:椭圆状的蛊毛窝和插入蛊毛窝中的细长蛊毛杆。然后,基于二者形态、结构特征及尺寸参数,建立毛缝结合仿生传感元件模型,对其分别进行了静态力学和动态力学理论计算,并利用ANSYS Workbench软件对模型进行了仿真分析,探究不同因素对其力学特性的影响。对于静态力学特性,通过研究元件最大应力值大小及其产生位置,可以得出仿蛊毛结构能够有效将应力集中于基部并提升应力值大小,而缝结构的存在引发了应力集中效应,促使应力值进一步增大,影响最大应力值大小的因素主次顺序依次为:长度比、缝结构数目、弹性模量比;对于动态力学特性:通过计算元件的固有频率,可以得出影响毛缝结合仿生传感元件固有频率的关键因素只有长度比。最后,以毛缝结合仿生传感元件理论模型为依据,制造毛缝结合仿生传感器,并将其应用于应变、振动和流量测量,且分别进行了传感性能分析。当将其应用于应变传感时,测量得出其灵敏度表征值GF最高可达479,响应时间为74ms,恢复时间为86ms,且经过2000次应力循环测量仍能保持稳定,具备良好的耐久度,证明毛缝结合仿生传感器可以很好地适用于应变检测;当将其应用于振动传感时,经过检测和计算可以得到其最大灵敏度为18186.858mv/g,平均灵敏度为9098.93mv/g,灵敏度区间为11mv/g~18186.858mv/g之间;频率响应范围为0~1000Hz;量程在0~5g之间;且传感器杆部长度越长,对低频激励的响应灵敏度越高;当将其应用于流量传感时,检测了一次气流冲击过程中毛缝结合仿生传感器的完整输出信号,结果表明毛缝结合仿生传感器在3.87s时产生电阻变化信号,随后对不同杆长的毛缝结合传感器进行1m/s~7m/s风速下输出阻值检测,结果表明输出电阻与风速之间呈非线性递增关系,且杆部长度越长,相应阻值越大。
