Abstract: Magnetoelastic wireless sensing is a new type of sensing technology, magnetoelastic wireless sensor is based on elements of magnetostrctive, signal in the sensor is activated and transmitted by magnetic field, there is no physical connection between sensor and detector, it belong to wireless, passive sensor, The paper introduces the work principle, classification and application of magnetoelastic wireless microbial sensor, To place the sensors in sealed container, monitoring microbial metabolic process online, and carried on the antibiotic medicines, such as the effi-cacy of online testing, has the incomparable advantage to other sensors, It provides an effective airtight nondestruc tive and in vivo realtime analysis new technology for food inspection research and clinical medical research, has wide application prospects.
Key words: magnetostrictive; wirelesspassive; magnetoelastic sensor; microbe
0引言
磁弹性无线传感技术是近10年迅速发展起来的一种新兴传感技术,基于磁致伸缩原理设计,为无线无源传感技术]。由于其无线无源特性,相关学者进行研究[2-3],并逐渐形成了传感领域的一个新分支-磁弹性传感器。传感器与检测仪器之间没有任何物理连接,其无线无源特征
决定了它在许多领域,如密闭不透明容器中的无损测定、活体分析和在线分析中具有其独特的优势。
微生物检测在食品检测、临床医学和环境检
测等许多领域都具有非常重要的意义,对微生物活细胞的快速检测是一个令人关注的课题。大肠杆菌,葡萄球菌属,绿脓杆菌,结核杆菌等都是自然界和临床上常见和重要的细菌,关系到人体的
