    • Development and optimisation of a zinc oxide nanowire nanogenerator 

      Van den Heever, Thomas Stanley (Stellenbosch : Stellenbosch University, 2013-12)
      ENGLISH ABSTRACT: This study developed and optimised zinc oxide (ZnO) nanowire-based nanogenerator. The nanogenerator works on the piezoelectric effect that is, a mechanical force is converted to an electrical voltage. ...

    • A zinc oxide nanowire pressure sensor 

      Van den Heever, Thomas Stanley (Stellenbosch : University of Stellenbosch, 2010-12)
      ENGLISH ABSTRACT: Measurement of pressure with zinc oxide (ZnO) nanowires was investigated. ZnO exhibits the piezoelectric effect, generating a voltage when pressure is applied to the material. This relationship between ...

    • ZnO nanowire gas sensor with UV-light for improved sensitivity 

      Van den Heever, T. S.; Hardie, G. L.; Perold, W. J. (SciDoc Publishers, 2013-04)
      ZnO nanowires are synthesised on a patterned substrate in order to see the response to different gases. Under ambient conditions the sensor shows very little response to any gas. A UV-light source is used to increase the ...
