  • DEVICE AND METHOD FOR DETECTING A SUB-SURFACE BTEX COMPONENT
    Publication number: 20240426781
    Abstract: A device for wireless detection of a BTEX component in a soil saturated with water, comprising an antenna, a permeable enclosure, and a sensor located in the enclosure. The sensor comprises: a piezoelectric substrate comprising lithium tantalate, an interdigitated transducer connected to the antenna for producing surface acoustic waves, a first mirror for a first echo of the acoustic waves, a second mirror for producing a second echo, a first layer of a first polymer between the transducer and the second mirror, the first polymer being adapted for reacting with the BTEX component so as to modify a travel speed of the second echo, and a first guiding layer comprising a metal and/or a polymer and located between the transducer and the first mirror.
