Abstract
Raman spectroscopy is a commonly used tool in bio-diagnostics and micro sensor technology. Surface-enhanced Raman scattering provides high signal enhancements especially at micro and nanostructured metallic surfaces. Micro tubular coil heaters have been widely investigated because of their extensive applications in PET Preformed Moulds, Hot Runner Nozzles & Bushings and Thin Walled Container Moulds and other Microsystems. This paper describes the characterization, experimental investigation and analysis of Titanium Nitride (TiN) micro tubular coil heater using Raman spectroscopy and Comsol multiphysics. The material characterization was performed using Raman spectrometer and the geometric optimization for the micro tubular coil heater was performed by simulating a wide range of possible geometries using COMSOLTM, a commercial Finite Element Analysis (FEA) package. The characteristic dimensions of the microstructures are varied and the results are discussed and compared to each other. The simulated results of micro tubular heaters having an improved temperature distribution over the sensing area and a higher density of integration is presented in this paper.
