Simulating Airborne Ultrasound Vibrations in Human Skin for Haptic Applications

The ability to focus high amplitude ultrasound onto human skin and elicit a tactile sensation in mid-air poses number of scientific opportunities challenges. For example, common issue with haptics is the relatively low forces generated on user’s skin, thus limiting dynamic range vibrotactile sensations that can be induced. To end, we develop viscoelastic rheological finite element model apply it show different acoustic radiation patterns generate varying forces, displacements, oscillatory targeted its nearby vicinity. Our framework allows for resolution computational exploration wide stimulus saving time resources spent running expensive experiments while.
