Research Institution
Not Available Sensant Corp intends to investigate the use of a new, non-contact ultrasound technology for the rapid detection of corrosion in large areas. Sensant Corp believes that recent improvements in transducer technology that now enable air-coupled inspection may overcome many of the traditional shortcomings of costly, time-consuming ultrasonic inspection systems for large areas. The recent application of micro-electromechanical systems (MEMS) technology to ultrasonic devices has created an advanced ultrasonic sensor with significantly improved dynamic range (110 db) and wide range of operating frequencies in air (2-12 MHz). These new ultrasonic transducers are fabricated in the same manner as a silicon chip using a technique known as micromachining. In many cases, these devices enable the possibility of air-coupled, non-contact inspection of materials as demonstrated by Sensant using aluminum and Plexiglas sheets. For this research, Sensant will characterize the acoustic properties of the multi-layer material to be inspected and will determine the required properties of an ultrasonic inspection system. Then, the company will develop a custom MEMS transducer to investigate the feasibility of ultrasonic inspection of multi-layer materials. To ensure rapid inspection of large areas, Sensant will evaluate both a longitudinal wave and lamb-wave approach using arrays of focused MEMS transducers.
