Detection of chemicals is required for many industries including the medical felids. MEMS sensors bring a novel solution for that requirement in small devices with its high sensitivity. One aspect of these sensors is that they can be customized for most applications. While they seem like the perfect solution, they are not without flaws. There are many aspects to chemical sensors. They can be simple or highly complex. In most cases, they are very accurate. It is possible, for example, for a cantilever sensor to detect mass changes in picograms. In this paper, some important design parameters to be considered for the optimization of a contilever beam glucose sensor performance are presented. Also the underlyning principle for this sensor is also simulated. This sensor works on the principle that a shift in resonance frequency of the cantilever beam indicates the amount of chemical absorbed which in turn indicates the presence of glucose molecules. This can be achieved by keeping the spring constant which is one of the parameters in defining resonance frequency constant. With this parameter kept constant, a change in mass which is the other resonance frequency parameter will cause a corresponding shift in resonance frequency and suggests the presence of specific molecules using a polymer engineered to selectively bind with only glucose molecules.
