Experience the manufacturing process of printed electronics in real life.
On March 20 and 21, 2019 the manufacturing of hybrid electronics and printed batteries were shown at LOPEC—in a trade fair environment.
As already evident from its name, electronics require power to function. This holds true for classical as well as for printed electronics. Rigid power supplies, e.g. coin cell batteries, go perfectly hand-in-hand with classical, rigid electronics.
However, to unleash the full potential of printed electronics the power source has to be flexible as well. By printing the battery, the power source can be made flexible and can be freely designed to incorporate just the right amount of energy for the envisioned use-case. Furthermore, for lots of computing power on a small scale, classical electronics are still the way to go. In order to combine these with printed electronics these silicon chips can be made flexible and, thus, combine the best of two worlds.
The demonstrator incorporated all of these and more technologies and aspects of printed electronics. A printed primary battery powers a circuit printed on polymer film. When the resistive switch is pressed, the flexible silicon chip generates a number and drives regular SMD-LEDs to display the number. This showcases the huge potential of combining printed electronics with adapted classical electronics to create novel and flexible devices.
OE-A members along the whole value chain collaborated to create this unique project, coordinated by the Hochschule der Medien.
The following companies participated in the 2019 production line: adphos Digital Printing, American Semiconductor, Coatema Coating Machinery, DuPont Teijin Films, Elantas Europe, ELMERIC, NovaCentrix, Pütz Folien, VARTA Microbatteries, VTT and Witte. The demo line was coordinated by Hochschule der Medien. These companies—representing the entire value chain—came together to join efforts in further developing emerging technologies as well as producing innovative products.
During the LOPEC Exhibition days at March 20 and 21, participants had the opportunity to take part in guided tours of the Demo Line.
