Electrothermal mechanism is the most widely used mechanism for providing large displacements at very small voltages. The new model is designed by combining asymmetric arm structure and a thin gold layer is inserted in the asymmetric arms which make it a typical bimorph structure. The microgripper presented here is electro-thermally actuated and optimized geometrically and materially to explore the effect of dimensional variation and material change on its performance. The in-plane, out of plane displacements, strain, stress, current density and temperature has been analyzed and the results are discussed.

The people working underground are generally caught unawares of the hazardous gas emission around their workplace. Hence an effective sensing and communicating system is required to effectively monitor and alert the neighbourhood to save them. This paper aims in finding out a way to quantitatively measure the hazardous gas molecules. The gravimetric type sensor works by absorbing the chemical in an absorbers compound, which changes the overall mass of the sensing element i.e. a cantilever, and its displacement. Here a micro-cantilever beam is fabricated using selective coatings on the surface to selectively absorb the hazardous gases.This change in displacement gives the measure of amount of gas present in that environment.The advantage of this technique are easy portability, sensitivity, repeatability and overall fabrication cost of the sensor.
