Design and control of an ultrasonic surface haptic device for longitudinal and transverse mode comparison

Mechanisms of Friction Reduction in Longitudinal Ultrasonic Surface Haptic Devices With Non-Collinear Vibrations and Finger Displacement

“…The deformation induced on the plate is the result of opposite surface tensions induced on both sides of the plate by the piezoelectric ceramics. As explained in [20], it was confirmed through cartography measurements that the lateral motion induced on the surface is primarily along the x axis, with very low comparative residual motion along the y and z axes (< 2%).…”

“…Fig. 1 shows the experimental equipment that includes a longitudinal surface haptic device, built as described in [20]. It is composed of an aluminum plate with dimensions 128 x 30 x 1.94 mm.…”

Conditional Generative Adversarial Network-Based Tactile Stimulus Generation for Ultrasonic Tactile Display

“…The associate editor coordinating the review of this manuscript and approving it for publication was Zheng Chen . using ultrasonic transducers have also been suggested [12], [13], [14] because of their compact structure and the potential for flexible predictability in vibration stimulation using amplitude modulation techniques [15]. Hence, it is important to focus on vibration as a sensing method for the quantification of tactile sensation, and an ultrasonic transducer is an effective way to apply vibration stimuli.…”
