Chemical Applications of FBAR sensors

Chemical sensors are possibly the most widely exploited category of sensors. They fulfill roles across industries including; pharmaceutical, oil & gas, industrial, military & security and environmental monitoring. The sensors utilised perform tasks such as process control and measurement, environment monitoring and chemical leak/threat detection. 

Current technology allows for the detection and monitoring of chemicals both inside and outside of systems to the limits required by government and industry standards. Worcester Scientific can manufacture sensors to meet these standards. However, the capability to go beyond these standards and measure amounts of chemicals in gases and liquids at ultra-sensitive levels is now available through our FBAR sensor technology. 

A 2018 PWC report on the ‘Trends of the Chemicals Market’, stated that chemical companies have been forced to “reconsider their place in the digital revolution”, resulting in intense research and development in digital technologies that complement their processes, products and services with the ultimate goal of increasing profitability. The development of accurate, innovative sensors will be key for the pursuance of the digitisation strategy as the new methods to increase profitability will need to be validated.   

Furthermore, the increasing popularity of Industrial Internet of Things (IIoT) alongside ordinary IoT devices and quality, big data sets will drive the need for embedded sensor systems inside ordinary objects. This could have domestic, industrial and security applications, detecting anything from increased levels of pollution in homes, a leak from a chemical plant or the deliberate release of a harmful substance. This type of integration is achievable through the utilisation of FBAR sensor technology as they have a nano-scale form factor.  

The FBAR sensor technology produced by Worcester Scientific is capable of detecting ultra-low (femtogram) levels of chemical substances, from hydrogen upwards. The specific detection of target chemicals is achieved through the coating of the FBAR sensor devices with specialists sensitising layers. Typical applications for the FBAR sensors would be to prevent major leaks within the chemical production industry through early detection and subsequent preventative maintenance and within the military and security industry, detecting harmful substances before they reach physiologically damaging levels.
