“…Surface acoustic wave (SAW) devices with interdigitated microelectrodes serving as interdigital transducers (IDTs) are commonly used in the information technology industry as electronic filters in delay line or resonator configurations [ 1 , 2 ]. A remarkable characteristic of SAW sensors is their sensitivity to a number of physical parameters, e.g., temperature [ 3 , 4 ], humidity [ 5 , 6 ], mass [ 7 , 8 , 9 , 10 , 11 ], and especially for the detection of (bio)chemical binding events on surfaces [ 8 , 9 , 10 ]. So far, SAW sensors are commonly used in two configurations.…”
