Controlled Vacuum Packed Particles as a Part of Machine Interface System

Abstract

Abstract. New opportunities of the Vacuum Packed Particles (VPP) and its application as a part of human-machine interface system are investigated. VPP are conglomerates composed of grains encapsulated in a tight, flexible envelope and submitted to an internal underpressure. The underpressure value has a great impact on the behavior and properties of the medium. This property may be used in various novel applications. The experimental results related to the stiffness and the vibration analysis and the controllable mechanical properties of VPP are given. The possibilities of numerical simulation of VPP behavior in a function of internal pressure are shown. The potential and perspectives for novel applications of VPP as a part of human-machine interaction are pointed out.
