A Study on Increasing Sensitivity of Microcantilever Biosensor of Different Geometries
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 …

Design and Simulation of a MEMS Piezoresistive Floating Element Shear Stress Sensor
Abstract: The paper presents the modelling, simulation and comparison of a MEMS piezoresistive (PZR) floating element shear stress sensor with various dimensions which has potential applications in underwater measurements. The floating element design utilizes a plate element of small mass suspended by four tethers. PZR patches are implanted at the root of the tethers. Shear stress is inferred by the deflection in the tethers and the corresponding change in the resistance …

Design and Simulation of Piezoelectric Energy Harvester
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 …

Exploration of Different Microcantilever Geometries for Thermal Sensing using COMSOL and Development of ANN Model
Abstract: In this paper, modeling and simulation results of a thermal sensor which is capable of producing increase in length and deformation with increase in temperature is analyzed. Different geometries of a microcantilever beam are accounted. Further, the simulated results are used to develop an artificial neural network (ANN) model of slotted triangular type of microcantilever. A comparative study of COMSOL and ANN results of different types of cantilever models is …
