Ultrasonic Transducers in Medical Applications

Ultrasonic transducers are based on piezo technology and serve as highly compact tools within IVD devices. These transducers utilize ultrasound waves to completely disintegrate cell structures without physical contact, minimizing any risk of contamination. This allows for direct analysis of cellular components such as DNA from blood or other bodily fluids, for instance in the detection of foreign DNA in virus testing. Additionally, these transducers facilitate rapid and efficient mixing of samples within analytical instruments and microfluidic units for IVD.

In liquid handling applications, ultrasonic transducers create powerful vibrations in the range of several 10 kHz while consuming comparably low amounts of energy. As such, they are highly versatile tools, suitable for use in both stationary medical devices and mobile point-of-care solutions. They can also provide support for other medical applications.   Additional miniaturized piezo transducers for nano-precision applications are also available.

How does Piezo Material Produce Ultrasonic Waves?

Piezo material produces ultrasonic waves by rapidly expanding and contracting when driven by an alternating electrical voltage. At high frequencies, these tiny mechanical deformations create pressure waves in air, liquids, or solids – one example here are ultrasonic motors.  By selecting the ceramic shape, resonance frequency, and drive signal, piezo transducers generate controlled ultrasonic vibration for sensing or actuation.
