Surface acoustic wave sensors are important division of micro-electro-mechanical systems (MEMS) that work on principle of modulating surface acoustic waves for sensing physical phenomenon. The sensor transduces an electrical signal into a mechanical wave which, dissimilar to an electrical signal that can be influenced by external physical activities. Surface acoustic wave (SAW) sensors are widely used as important component of surface acoustic wave devices. Surface acoustic wave devices are being used as actuators, sensors, resonators, and filters. These SAW devices can be effectively used in gaseous and liquid environments and these products are very sensitive to changes in the surface environment. Surface acoustic wave sensors enabled devices help in measuring a number of parameters such as temperature, pressure, electrical conductivity, liquid density, liquid viscosity etc.
The Surface Acoustic Wave (SAW) Sensors market is gaining importance due to increase in its applications in various fields such as safety monitoring, communication and military among others. The growth of Surface Acoustic Wave (SAW) sensors market across different countries is driven by rising demand of SAW devices and advanced cell phone infrastructure having SAW components. Moreover, the rising penetration of telecommunications network in developing countries, new product innovation, and low manufacturing cost are propelling the market for SAW sensors. And it is estimated that the market for Surface Acoustic Wave Sensors would grow with an impressive CAGR, for the period between 2016 and 2024.
Another trend driving the growth of the SAW sensor market is the fact that, globally it is becoming obligatory to implement the Tire Pressure Monitoring System (TPMS) in light vehicles to avoid unsafe driving conditions. The main purpose of TPMS is to warn the driver when one or more than one of the tires in the vehicle is under-inflated. Various laws issued in both Europe and North America has made it compulsory to install TPMS in light weight vehicles. And since there is a major use of Surface Acoustic Wave (SAW) sensors in TPMS it is expected that this factor will augment the SAW sensors market in both Europe and North America.
Major restraints for growth of SAW sensor market are replacement of the SAW sensors by other sensors in conventional applications and low mass sensitivity. Moreover, lack of compatibility of the SAW sensors is also hindering the growth of the market.
