Ultrasonic phased arrays are used to deliver midair haptic feedback in both research and commercial applications and strongly rely on the Acoustic Radiation Pressure (ARP) that arises at the air-skin interface. The ARP generated by ultrasonic mid-air haptic feedback technology today is orders of magnitude lower than most forces involved in traditional contact haptic devices, however can be leveraged to produce a rich plethora of perceptible tactile sensations. Therefore, how a viscoelastic structure such as the human skin responds to the ARP is an important research topic that merits further investigation. To that end, we detail herein a methodology to investigate the mechanical response of viscoelastic materials to this type of stimulation. Our research is divided into a laser doppler vibrometry experimental study and a Finite Element Model (FEM) computer simulation of a skin-mimicking phantom slab. Through comparison of experimental and simulation results under different ultrasound stimulation schemes we observe good qualitative and quantitative agreement, thus successfully advancing towards the development of a numerical tool for optimising ultrasonic mid-air haptic stimuli. |
