Real-Time Thermoacoustic Ultrasound Sensor
Researchers at the University of Alberta have developed a miniature thermoacoustic sensor capable of measuring ultrasound intensity via direct coupling to a transducer. Designed to complement traditional ultrasound calibration equipment, such as radiation force balance and hydrophone, our sensor can be used to continuously measure low intensity (below 100Hz) ultrasound output in real time during industrial processes, to ensure accurate output. The sensor may provide process improvements for end users.
Low intensity ultrasound is rapidly growing in use and in a number of industries, including bioprocessing, enzyme activation, fermentation, water treatment and non-destructive material testing. Low intensity ultrasonication has been shown to provide cost-effective improvements in productivity, on a commercial scale, due to availability and improved energy efficiency of commercial scale transducers, low maintenance costs and process improvements; however; precision control of intensity is critical. Our real-time sensor may provide an important competitive advantage to manufacturers and users of low intensity ultrasound transducers.
