The study, titled Chemical Sensors, says the development of multianalyte sensors and the use of biosensors in high-density arrays will also support demand, while biosensors used outside of medical applications will continue to face considerable challenges from other existing detection and measurement methodologies. Optical sensors — including products based on infrared, fiber optic, photoionization, fluorescence, chemiluminescence, light-emitting diode, laser and ultraviolet technologies — are expected to continue to benefit from their high sensitivity, stability, immunity to interference and product improvements, such as smaller size and enhanced ruggedness. The large automotive sensor market is also expected to post favorable growth through 2012, due to a rebound in motor vehicle production and the introduction of new sensor applications, such as cabin air quality control. The development of lower-cost, more durable and higher-performance chemical sensors is expected to drive demand in other markets as well, such as process industries, water and wastewater monitoring, and homeland security.
