实时检测黄体微球菌（M. luteus）浓度描述使用远程查询（无线，被动）磁弹性传感器。通过磁场遥测测量液浸式磁弹性传感器的谐振频率随液体培养基在生长和繁殖过程中消耗培养基中的营养物质而变化。利用所述技术对10(3)~ 10(7)个细胞ml（-1）的黄体芽孢杆菌浓度进行了定量，并对黄体芽孢杆菌的耐盐性进行了研究，证明了该传感器的应用。传感器和监测电子设备之间没有任何物理连接，便于无菌操作，使传感器平台非常适合从内部监测细菌，例如密封的食品容器。
The real-time detection of Micrococcus luteus (M. luteus) concentrations is described using a remote query (wireless, passive) magnetoelastic sensor. The resonance frequency of a liquid-immersed magnetoelastic sensor, measured through magnetic field telemetry, changes in response to property changes of a liquid culture medium as M. luteus consumes nutrients from the culture medium in growth and reproduction. Using the described technique, the concentration of M. luteus was quantified from 10(3) to 10(7) cells ml(-1), and the salt tolerability of M. luteus was also investigated, which was demonstrated as an application of the sensor. The lack of any physical connections between the sensor and the monitoring electronics facilitates aseptic operation, and makes the sensor platform ideally suited for monitoring bacteria from within, for example, sealed food containers.
