SAW excited by input interdigitaltransducer is divided centrosymmetrically into two paths detected by their output interdigitaltransducer.
它将输入叉指换能器激发的SAW中心对称分成两路并由各自的输出叉指换能器检测输出。

On the basis of SAW technology, this thesis designs a SAW humidity sensor. Include the design of IDT (interdigitaltransducer), the thin film as well as the frequency measurement system.
To solve these problems, the properties of Lamb wave excited by interdigitaltransducer in the piezoelectric substrate covered by liquid were studied based on its piezoelectricity and anisotropy.
