The broad frequency range of operation is one of the transducers' advantages over piezoelectric materials.
The transducers are connected to an output device on the keyboard base.
He and his group are using a manufacturing process that they hope will make the transducers more compact.
The width of this stripe is about four times the depth of water under the transducers.
Dr. Khuri-Yakub's research on the transducers has been sponsored throughout the last decade by several organizations, including the Office of Naval Research.
Dr. Khuri-Yakub has obtained research financing from the National Institutes of Health to use the transducers to go inside arteries to search for plaque.
The width of the stripe is about four times the depth of water under the transducers, so in water with 250 meters under the transducers, we map a stripe about a kilometer wide.
Many of the transducers used in everyday life operate in both directions, such as the speakerphone on certain intercoms.
The transducers were manufactured at the V.Ye.
Figure 4 On-axis amplitude responses of the transducers.
The transducers recorded AEs during the loading experiment.
