Master’s Thesis Abstract

Two novel geometries of dielectric elastomeric actuators have been designed, optimized and a selection methodology for these two actuators for specific clinical applications have been developed. Designed two novel DEA geometries for large displacement-smaller force and small displacement -larger force applications. Developed an analytical model for the designed geometries and optimized the parameters using MATHEMATICA 7.0 . Simulated the geometries in ANSYS and the results were compared to the analytical model. Devised an algorithm for selecting these devices for specific applications and made a prototype of the device and compared the performance with the modeled results.  link to my thesis

Mini -Projects during  Master’s

Spasticity quantification & device for measuring the spasticity. A quantification methodology for spasticity in the patients affected by stroke or cerebral palsy has been developed and a device was designed to measure it.

Biomechanical testing is essential to understand the effectiveness of some surgical procedures. During abdominal surgeries, the surgeon may accidentally touch the intestinal tissues resulting in aberrations. Developed an instrument for testing the effect of these aberrations in rats and the device applies a constant force on the rat intestine. The aberration is quantified by the surface roughness of the applicator and the force applied.

A mathematical model of the kinetics of the neurotransmission was used to find out the effectiveness of the “burst” as a method of transferring information between the neurons. This work was done as part of a project done at CSHL Asia Workshop- July 2010, held in Suzhou China

Bachelor’s Project
