#2 Online-Session »Advanced flexible circuits for novel applications«

PCB technologies for foil based conformable electronics

Conformal electronics as a new paradigm in electronic system fabrication will be presented. Such systems are build-up so that they can be deformed and stretched, and are supple to adapt to arbitray shaped and even dyamically changing surfaces. In this presentation foil based conformal electronics will be discussed.

Speaker: Dr. Thomas Löher

Be part of our second lecture session on February 15, 2022: Within 45 minutes we would like to show you one presentation and afterwards our experts will be available in a deep dive for your questions and comments. Participation is free of charge, registration is required.

A method to fabricate stretchable and thermo-formable electronics substrates will be presented. The basis of such build-ups are thermoplastic polyurethane foils with a typcial thickness of 100 µm. The foils are soft and can be stretched up to 500 % without disrupture. Using prinited circuit board technologies copper tracks with thickness of 18 or 35 µm are defined on top of the polyurethane foils. The interconnect tracks are designed with meander shape in order to be stretchable. Substrates are further equipped with a solder mask and finally the interconnets fully embedded into the polyurethane matrix. Electrical components can be mounted using conventional component assembly techniques, complemented eventually by encapsulation of individual components. The mechanics of single and multiple deformation of such circuits will be presented and discussed.

Electronic cirucits fabriacted in this way can be attached to further carriers like polycarboante panels or various textiles, which allow wide range of applications to be realized.

Fraunhofer IZM stands for application-oriented, industry-oriented research.
With its technology clusters in the field of wafer and substrate process technology as well as its high competence in simulation and metrology, Fraunhofer IZM covers the entire range required for the realization of reliable electronics and their integration into applications. With our expert session series "Advanced flexible Circuits for novel Applications"we want to introduce you to the world of flexibles!

Combination of search terms

You can combine search terms with and, or and/or not, e.g. Philo not logy.


You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).


Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.

Selection criteria

You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).

If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
