Differential Sensing of Lamb Wave Using Piezoelectric Transducer for Baseline-Free Tactile Sensing on a Glass Plate

This paper utilizes only the anti-symmetric fundamental (<i>A</i>₀) mode of Lamb waves for tactile sensing to realize a baseline-free ultrasound-based touchscreen. Disk-shaped piezoelectric transducers are mounted in pair on a glass plate to excite and detect pure <i>A</i>₀ mod...
