vibration

Vibration-absorbing, sound-damping materials such as sheets of rubber and expanded foam tend to be thick, bulky and soft. A new material is a big exception to that tendency, however, as it absorbs vibrations while staying stiff and thin.

For the past year or so, a student team from the Eindhoven University of Technology has been working on a wearable that could allow folks to understand what's being said in another language through vibrations on the arm.
