Influence of Axial Mechanical Stress on the Xonductivity of Fullerite Powder

Abstract

The possibility to use powder consisting of fullerite microcrystallines as a device sensitive to the external axialmechanical load is considered. We suppose that the change of conductivity of fullerite microcrystalline powder as afunction of external mechanical stress will be useful for the creation of nanoscale devices of sensor electronics. This neweffect based on changing of intermolecular distance between fullerene molecules due to the action of external mechanicalforce, which can change the distance between fulerene molecules because of weak van der Waals interaction exists. Thefounded effect is quite linear and sensitive to external mechanical stress is better then in well-known pressure transducersis based on silicon technology.
