Description
Summary:We report an enhanced actuation in bulk carbon nanotubes (CNTs) under coupled electric and magnetic fields, which is much higher than that evaluated in the presence of individual fields. Coupled electric and magnetic fields induce a directional actuation demonstrating a transformation from polarity independent to dependent actuation behavior of CNTs. Both qualitative and quantitative analyses are performed to understand this transformation in the bulk CNTs. Moreover, actuations along radial and axial directions of CNTs have also demonstrated a similar directional behavior. The transformation of electrostrictive to piezoelectric behavior is observed in carbon nanotube under coupled electro-magnetic field. Five times higher actuation response was observed under coupled field as compared to the individual fields.
