MEMS-based resonant sensor arrays : selective detection of volatile and toxic chemicals

With growing concerns about homeland security, public health, and environmental cleanliness, there is a strong need today for robust chemical sensing systems that are portable in addition to being highly sensitive. While there are many options available for gaseous chemical detection and identification, not all are well-suited toward the creation of a portable device. Boston MicroSystems, Inc. (BMS) has developed a resonant chemical sensor that is predicted to meet the performance needs of the current market in terms of gas sensitivity, operational reliability, and overall device portability. Desirable device characteristics are attained through integrating aluminum nitride and silicon carbide in processes that are protected through a strong base of intellectual property. By developing a standardized platform for gas detection based on this sensor technology, barriers to entering the targeted markets may be overcome.
