AB  - Cellulose is an abundant natural piezoelectric polymer and is also a renewable 
      resource of significant importance. Here in this work we realize an enhanced 
      piezoelectric response with cellulose in a polydimethylsiloxane (PDMS) matrix by 
      forming a nanocomposite with the incorporation of gold nanoparticles (Au NPs). In 
      the Au NP-cellulose/PDMS nanocomposite an enhancement in the dielectric constant 
      is recorded due to the presence of cellulose alone and a reduction of dielectric 
      loss is found owing to the presence of Au NPs. This opens the possibility of 
      realizing a nanodielectric material from the nanocomposite under current study. 
      This also indicates the significant potential of the nanocomposite towards energy 
      conversion applications. Subsequently, a mechanical energy harvesting device was 
      fabricated using the Au NP-cellulose/PDMS nanocomposite, which is named as a 
      piezoelectric nanogenerator (PNG). The PNG delivered an enhanced open circuit 
      voltage of  approximately 6 V, short circuit current of  approximately 700 nA and a peak power density of 
      8.34 mW m(-2) without performing any electrical poling steps. The PNG could 
      charge a 10 muF capacitor to 6.3 V in 677 s and could light two commercial blue 
      light emitting diodes (LEDs) simultaneously. The PNG exhibited a good energy 
      conversion efficiency of 1.8%. A touch sensor application of the PNG is also 
      shown.
