We are launching a new joint project 2024-2027

partners: with institutes and companies from South Korea, a company from Austria,

Fraunhofer Institute and MEINHARDT Ultrasonics

Topic: TexPie - Textured Lead-free Piezoceramic Materials by Additive Manufacturing for High-Performance Ultrasonic Transducers

Project summary

Piezoceramic materials change their shape and exert forces under electrical fields. They are essential in many industrial, medical and consumer applications. The most powerful and therefore most commonly used piezoceramic materials contain lead. Lead-free piezoceramic materials which are in line with the RoHS directive of the EU are known, but still have inferior properties and higher costs. The aim of the TexPie project is to improve their properties using texturing. Their applicability should be demonstrated in power ultrasonic applications. Additionally, the use of additive manufacturing for shaping of piezoceramic components avoids machining steps and thus hazardous waste. Near net-shape manufacturing and optimizing thermal processes will reduce energy consumption in thermal processes and machining effort to net-shape for piezo ceramic components with high complexity, thus supporting the future European circular and sustainable industry.

our part: selection and description of demonstrator applications in the field of high-performance ultrasound, primarily sonochemistry and medical HIFU

August 2020
The UvPaa network project Fish Farm Wastewater with AWI and Geomar is coming to an end,

the results are promising.

Despite Corona, production and development continued -
in June/July, multi-frequency systems were delivered to France and Australia.
______________________________________________________________________________
August-September
The 3rd generation of the multifrequency system is under development,

first tests have been carried out.

January 2020

20 units consisting of a 35 kHz ultrasonic bath with heating and a 20 kHz sonotrode laboratory unit with 200 Watt, we have delivered to a university in Great Britain.

________________________________________________________________________

We participate in numerous national and international congresses and fairs and continuously expand our ultrasound systems including new fields of application.

Since 2018 Dr. rer. nat Martin Ecke our team, as a chemist he has many years of experience in sonochemistry.

A new joint project - funded by the BMBF - was start in September 2018 and
runs until 2021. We look forward to u.a. the fish farming our experiences and
Allowed to use multi-frequency technology. Our partners are AIMES GmbH and the renowned GEOMAR Kiel Institute as well as the ALFRED-WEGENER-Institut Bremerhaven.
