title: Skin surface shock wave.
abstract: This paper discusses the Skin Surface Shock Wave which is generated after we impart an impulsive force to human skin. The force is given by an air jet during 200 [ms]. The basic behavior of shock wave is measured by a high speed camera with the frame rate of 2000 [Hz]. Through the experiment, we found an interesting behavior where there exists a remarkable difference between young and elder subjects especially during the recovery phase, while there is nearly no difference between two during the force imparting phase.
