AB  - Cellulose, a major constituent of our natural environment and a structured 
      biodegradable biopolymer, has been shown to exhibit shear piezoelectricity with 
      potential applications in energy harvesters, biomedical sensors, electro-active 
      displays and actuators. In this regard, a high-aspect ratio nanofiber geometry is 
      particularly attractive as flexing or bending will likely produce a larger 
      piezoelectric response as compared to axial deformation in this material. Here we 
      report self-assembled cellulose nanofibers (SA-CNFs) fabricated using a 
      template-wetting process, whereby parent cellulose nanocrystals (CNCs) introduced 
      into a nanoporous template assemble to form rod-like cellulose clusters, which 
      then assemble into SA-CNFs. Annealed SA-CNFs were found to exhibit an anisotropic 
      shear piezoelectric response as directly measured using non-destructive 
      piezo-response force microscopy (ND-PFM). We interpret these results in light of 
      the distinct hierarchical structure in our template-grown SA-CNFs as revealed by 
      scanning electron microscopy (SEM) and high resolution transmission electron 
      microscopy (TEM).
