The construction, measurement, and modeling of an artificial cochlea (ACochlea) are presented in this paper. An artificial basilar membrane (ABM) was made by depositing discrete Cu beams on a piezomembrane substrate. Rather than two fluid channels, as in the mammalian cochlea, a single fluid channel was implemented on one side of the ABM, facilitating the(More)
The synthetic aperture focusing technique (SAFT) is a well-established method for improving the resolution of an ultrasonic image. A major shortcoming is the inherent assumption that the pulse reflected from a flaw has a spectral content that is independent of the flaw's location relative to the transducer. In this project, we address the issue by using(More)
