Quality is Top Priority: Ultrasound Piezo Elements in Medical Technology
Ultrasound, which is sound above the human hearing limit of approximately
16 kHz, is applied in numerous ways in medical engineering and
research. Applications range from distance measurement and object
recognition, filling level or flow rate measurements, through highresolution
material tests, up to medical diagnosis and therapy.
Here, piezo elements often play a key role, as is also the case in a new
system for the wireless monitoring of mother and child during pregnancy
and birth (Fig. 1).
