| Description | The research developed new methods to convert simple excitation signals into broadband signals suitable for imaging. The technology is based on solitary waves progressing in closely grouped spheres, similar to newtons cradle but on the micro-scale. In this study, an analytical model is created to predict the motion of a finite material attached to a granular chain as a matching layer. An experimental setup is created to verify the estimated motion of the matching material with the new model. The setup consists of a one-dimensional chain of six aluminum spheres, a vitreous carbon matching layer, and an ultrasonic horn. The ultrasonic horn generates a narrow-band input of a 25-cycle sinusoidal tone burst with a center frequency of 73 kHz and a-6-dB bandwidth of 3.5 kHz.The output is measured in water as a train of wideband ultrasonic pulses with a-6-dB bandwidth of 280 kHz,which is predicted with the model as 252 kHz. The results derived in this research work indicate that such chain like systems may be of interest to the biomedical ultrasound community,where a train of high-frequency impulses might have applications in imaging, microbubble dynamics, and high-intensity therapy |
| Exploitation Route | The technology could eventually lead to new types of transducers that can be used for both diagnostic imaging and therapeutic purposes. |
