带状磁致弹性传感器可以被认为是声学钟的磁性模拟;响应于外部施加的磁场脉冲，传感器发射具有特征谐振频率的磁通量。可以使用拾波线圈在测试区域外部检测磁通量，从而实现对传感器的查询远程监控。磁致弹性传感器的特征谐振频率响应于质量负载而变化[L. D.朗道和E. M. Lifshitz，Theory of Elasticity，3rd ed.（Pergamon，纽约，1986），p. 100].因此，远程查询化学传感器可以通过将磁致弹性传感器与质量变化的化学响应层组合来制造。在这项工作中，磁致弹性传感器涂有陶瓷，纳米多孔TiO 2的湿敏薄膜，使远程查询湿度传感器。(C)2000年美国物理学会。[S0021-8979（00）32708-6]。
Ribbonlike magnetoelastic sensors can be considered the magnetic analog of an acoustic bell; in response to an externally applied magnetic field impulse the sensors emit magnetic flux with a characteristic resonant frequency. The magnetic flux can be detected external to the test area using a pick-up coil, enabling query remote monitoring of the sensor. The characteristic resonant frequency of a magnetoelastic sensor changes in response to mass loads [L. D. Landau and E. M. Lifshitz, Theory of Elasticity, 3rd ed. (Pergamon, New York, 1986), p. 100]. Therefore, remote query chemical sensors can be fabricated by combining the magnetoelastic sensors with a mass changing, chemically responsive layer. In this work magnetoelastic sensors are coated with humidity-sensitive thin films of ceramic, nanodimensionally porous TiO2 to make remote query humidity sensors.
