The effect of axial mechanical stress on fullerite powder conductivity

The possibility to use powder consisting of fullerite microcrystals as device sensitive to external axial mechanical load is considered. As we suppose the change of conductivity of fullerite microcrystal powder as function of external mechanical stress to be useful for creation of nanoscale devices of sensor electronics. This new effect based on changing of intermolecular distance between fullerene molecules due to action of external mechanical force, which can change the distance between fullerene molecules because of weak van-der-Waals interaction exists. The founded effect is quite linear and sensitivity of this effect to external mechanical stress more then in well-known pressure transducers based on silicon technology.
