Electrostatic oscillation of CNT bundles

Electrostatic oscillations of conductive CNT bundles have been successfully demonstrated in air environment. Three unique characteristics have been observed and characterized. First, CNT bundles have been constructed by a simple “pick, stick and break” process using a regular probe tip from vertically aligned CNT forest on a silicon substrate. Second, CNT bundles have been actuated statically under applied DC voltages. Third, CNT bundles oscillated following the applied AC input frequencies. As such, this research present electrostatic oscillation of CNT bundles and could potentially open up a new class of actuator/oscillator research for applications in the general field of MEMS and NEMS.
