  Design and Simulation of Piezoelectric Energy Harvester

  By Rajashekhar Savadi, M Mallikarjun, Shivashankar Huddar, B. G. Sheeparamatti

  Abstract: SU-8 has the high aspect ratio, good pattern ability property, mechanical and chemical stability. The energy harvester structure is made of SU-8 as substrate and zinc oxide as the piezoelectric layer. The optimal dimension is found out to be 500 µm×20 µm×3 µm. The simulation shows that for input 10 N/m2 at the frequency of resonance of the structure, the energy harvester generates 13.1 mV. Keywords: Zinc Oxide (ZnO), cantilever …

  A Study on Increasing Sensitivity of Microcantilever Biosensor of Different Geometries

  By Rajashekhar Savadi, Basavaraj Bagewadi, Prashant Revadigar, Shivukumar Gouda, Shivashankar Huddar

  Abstract: In this paper, the authors present the activities within their research group on increasing the sensitivity of microcantilever of SU-8/2050. They believe that SU-8 is an interesting polymer for fabrication of cantilevers for biosensing due to its simple processing and low Young’s modulus. They show that the SU-8 cantilever surface can be functionalized directly with receptor molecules for analyte detection, thereby avoiding gold layer. To increase the overall sensitivity of …
