AB  - Relative displacements between the atomically smooth, nested shells in 
      multiwalled carbon nanotubes (MWNTs) can be used as a robust nanoscale motion 
      enabling mechanism. Here, we report on a novel method suited for structuring 
      large arrays of MWNTs into such nanobearings in a parallel fashion. By creating 
      MWNT nanostructures with nearly identical electrical circuit resistance and heat 
      transport conditions, uniform Joule heating across the array is used to 
      simultaneously engineer the shell geometry via electric breakdown. The biasing 
      approach used optimizes process metrics such as yield and cycle-time. We also 
      present the parallel and piecewise shell engineering at different segments of a 
      single nanotube to construct multiple, but independent, high density bearings. We 
      anticipate this method for constructing electromechanical building blocks to be a 
      fundamental unit process for manufacturing future nanoelectromechanical systems 
      (NEMS) with sophisticated architectures and to drive several nanoscale 
      transduction applications such as GHz-oscillators, shuttles, memories, syringes 
      and actuators.
