Technology is used in high-end technology markets, such as medical technology, mechanical and automotive engineering or semiconductor technology, but is also present in everyday life, for example as a generator of ultrasonic vibrations in a cleaning bath for glasses and jewelry or in medical tooth cleaning.
Piezo-based ultrasonic sensors are used as park distance control and monitor the heartbeats of babies prior to birth. Ultrasound is defined as sound at frequencies above the human hearing frequency range, i.e. starting from around 16 kHz. Industry, medical technology and research use this frequency range for many purposes. Applications range from distance measurement and object recognition, filling level or flow rate metering, to ultrasonic welding or bonding,
high-resolution material tests, and medical diagnostics and therapy.
