- This paper reports on the design and manufacture of the world's first fractal ultrasonic transducer. This contributed to a work package in the £11M EPSRC/RCNDE/industry strategic partnership (EP/L022125/1); 16 large full member companies and over 30 associate. This work led to a funded EPSRC project EP/P005268/2 (£517K, iNEED: including Non-destructive Evaluation in Engineered Design). Modern ultrasonic transducers have a single length scale design and operate at a single frequency. This fractal transducer has a range of length scales which allows it to operate at a range of frequencies. This enables the transducer to produce higher resolution images for medical imaging.
