Tactile Sensing: Sound, vibration and friction between soft materials under light loads

(Ongoing Project)



Tactile perception of materials and surface texture involves friction under light normal loads and is fundamental to further advancing areas such as tactile sensing, haptic systems used in robotic gripping of sensitive objects, and characterization of products that range from the softness of fabrics to effects of surfactants, such as lotions, on skin. This research focuses on the development a new apparatus and a technique to measure friction simultaneously with dynamic quantities such as accelerations, forces, and sound pressures resulting from light contact over a soft material, much like a finger lightly touching a soft material. The methods under development is a novel friction and adhesion measurement method that can be particularly useful for soft materials and light normal loads.
