The 2019 IEEE International Symposium on the Applications of Ferroelectrics (ISAF) was held at the Swiss Tech Convention Center near the EPFL in Lausanne, Switzerland, from July 14th to 19th, 2019 within the joint Conference, “F2cπ2 2019”, that united ISAF with several other international and European symposia :
-International Conference on Electroceramics (ICE);
-European Meeting on Ferroelectricity (EMF);
-International Workshop on PiezoMEMS (IWPM);
-Piezoresponse Force Microscopy Workshop (PFM).
The full name of the Conference was thus “2019 ISAF-ICE-EMF-IWPM-PFM Joint Conference”. It was chaired by Prof. Paul Muralt (General Chair) and Prof. Dragan Damjanovic (General Program Chair), both from EPFL. For the joint Conferences, Prof. Geoff Brennecka (Colorado School of Mines, USA) was ISAF Chair, Prof. Harry L. Tuller (MIT, USA) was ICE Chair, Prof. Brady Gibbons (Oregon State University, USA) was IWPM Chair and Prof. Neus Domingo (Catalan Institute of Nanoscience and Nanotechnology, Spain) was PFM Chair.
The F2cπ2 2019 brought together many diverse fields with focus on electroceramics and ferroelectrics, and hosted many of the world’s most prominent researchers from academia, national laboratories, and industries.
In total, 859 participants from 39 different countries were registered to F2cπ2 2019 and presented their work during the numerous technical sessions. The Conference has seen a strong participation from Germany and USA (100 attendees each), followed by Japan (78), Switzerland (65), China (63) and South Korea (62). Many countries with populations below 10 million have strong groups in ferroelectricity. The ratio of ferroelectricians/million people is highest in Luxembourg (20), and above 5 in Switzerland and Slovenia, based on F2cπ2 2019 participants.
Technical Program of F2cπ2 2019:
Talks were arranged in up to ten parallel sessions, for a total of 140 different oral sessions. Moreover, three poster sessions were presented (on July 15th, 16th and 18th). A total of 410 talks (including 133 invited talks) and 273 posters were presented at the F2cπ2 2019 IFAAP Conference. 390 contributions (oral + posters, including 47 invited) were assigned to ISAF alone.
Every morning the sessions were opened by Plenary lectures delivered by prominent scientists, who provided the audience with cutting-edge research and insightful views into the present and future trends in research in ferroelectric and electroceramic materials and the related characterization techniques. One Plenary Speaker was related to the PFM Workshop and IWPM each. Two Plenary Speakers each were associated with EMF and ICE conferences, whereas four were related to the ISAF.

It took place in the evening (18:00 – 20:00) of July 16th, and consisted in a series of 1-minute presentations given by a total of 36 student participants, in which they presented their research, the concept behind it, and its applications, with an eye on marketing. Three students were selected by a Jury composed almost half/half by members of the Industry and the Academia. The prizes were announced during the Banquet on July 18th.
Social and “not-strictly technical” Program of F2cπ2 2019
The Social Program of the F2cπ2 2019 Conference was also very dense and provided the attendees with numerous opportunities to network, strengthen existing collaborations or establish new research ties with worldwide partners.
First of all, on Sunday evening (July 14th), a Welcome Reception was held, in which all participants could have a first contact with the location and other attendees. The following day, private receptions were held for Members of the respective Societies.
The IEEE President’s reception was given on Tuesday, July 16th, by Prof. Nazanin Bassiri-Gharb, the President of IEEE-UFFC. During this occasion, Prof. Bassiri-Gharb recognized IEEE-UFFC Members who contributed to the organization of the F2cπ2 2019 Conference, and the speakers of Plenary and Tutorial lectures. It was also a very nice occasion to wish Happy Birthday to Prof. Paul Muralt, General Chair of F2cπ2 2019!
The Women in Engineering – Unconscious Bias Workshop took place on July 18th, sponsored by UFFC-S Women in Engineering, and facilitated by Gillian Arnold (Director, Tectre). Unconscious bias is a view or attitude towards characteristics such as race, gender, age, etc, that exist outside one’s conscious awareness. Everyone has unconscious bias and it can have a negative impact on innovation and research progress. Research has shown that diversity and inclusion increases productivity and creativity, results in faster problem solving, and leads to higher employee/student engagement. Therefore, it is imperative to remove implicit bias to improve diversity and inclusion in the workplace.
Unconscious bias training creates awareness for implicit biases, provides tools to adjust automatic patterns of thinking, and aims to eliminate discriminatory behaviors. Aspects of this powerful concept were discussed during the Workshop. The main points of this activity were the following:
- Defining unconscious bias.
- Exploring the benefits of removing unconscious bias.
- Understanding how biases are formed.
- Auditing own unconscious biases.
- Defining ways to implement change (if necessary) into one’s own organization.
Excursions were held in the afternoon of Wednesday, July 17th, and many different options were available to the attendees:
- Visit to Chateau de Chillon by boat or by train, including a stroll in the city center of Montreux.
- Visit to the chocolate factory in Broc, castle of Gruyère, and a cheese plant, including a rural-style dinner.
- Visit to the Museum dedicated to Charles Chaplin in the town of Vevey.
- Visit to Rocher de Naye, a mountain overlooking Lake Geneva, including a ride on a traditional mountain train.
- Visit to the Vineyards of Lavaux, including wine degustation.
For the ones who preferred to remain in town, Lake Geneva offered lots of opportunities for a relaxing afternoon bathing and barbequing in a wonderful scenery.
The Conference Dinner was organized in the main hall of the Swiss Tech Convention Center, which was used for plenaries during the day. The main course was preceded by talks by Paul Muralt and Dragan Damjanovic, who presented some statistics about the conference and information about the 2020 ISAF Conference (to be held in Keystone, Colorado, USA). The dinner was accompanied by music, and this time the musical offer was reminiscent of the Alpine culture typical of Switzerland: a trio of alpine horns played both traditional and modern tunes, and also offered to interested ferroelectricians the opportunity to give it a try!
During the Banquet, Dr. Astri Haugen (DTU, Denmark) and Lukas Riemer (EPFL, Switzerland) presented the Student Paper Competition Award, whereas Prof. Dr. Jacob L. Jones (NCSU, USA) and Stuart Burns (UNSW, Australia) presented the Student Pitch Competition Awards. Concerning the latter, the “Industry’s Choice Award” went to Àlvar Torelló (University of Luxembourg, Luxembourg) for his presentation “Electrocaloric heat exchangers for high efficient cooling”. Scarlet Kong (UNSW, Australia) got the “Academia’s Choice Award” for her presentation “Texture: Get your ducks in a row”. Finally, the “First Place Award” went to Nicolas Godard (LIST, Luxembourg) for “Inkjet printing of large-area piezoelectric thin films”.
During the Conference Banquet, also the IEEE UFFC Society Awards and Recognition for Ferroelectrics were presented by Geoff Brennecka (Awards Chair for Ferroelectrics).
-The IEEE UFFC Distinguished Lecturer 2019 is Prof. Clive Randall of Pennsylvania State University, USA. He can be invited by research groups worldwide until June 2020 to carry out lectures. More details can be found at www.ieee-uffc.org.
After a short introduction on how the Awardees for Ferroelectrics are selected, Geoff Brennecka announced the 2019 recipients:
