piezoelectric synonyms
the temperature at which the PZT is polarized
680°
curie point
application of a chemical agent to reduce or eliminate infectious organisms on an object
disinfection
cylindrical appearance
sound pulse emmitted from front
wire connecting the transducer to the system
transducer construction
case
electrical cord
acoustic insulator
PZT or active element
wire
matching layer
backing material (damping material)
components of transducer
range of frequencies that a transducer operates within
bandwidth
is a result of using the damping palyer in a transducer
Low Q factor
imaging=pulsed
non-imaging=continiuos
imaging
vs non imaging
transducers
created byt he electrical signal applied to a crystal
crystal size determines freq output and speed of sound
transducer freq creation
freq at which something naturally vibrates
resonant freq
