Hybrid Integration Made Possible by Printed Electronics

One of our goals is the continuous further development of printed electronics to make them more marketable and usable in all areas.

On the way to completely printed flexible circuit boards, we are working on a hybrid integration within the BMBF-funded research project 2-HORISONS in which silicon chips are to be placed directly on the conductor tracks of the printed films. This technology enables a partial integration of a classic PCB and also part of the peripheral electronics to be integrated directly into the printed sensor. This minimizes the number of connectors and connecting wires, an important aspect for saving space and costs. In this specific example, the number of connections can be reduced by 80%, leading to the micro-controller (with integrated analog-to-digital converter) for controlling and reading the sensors.
 
The next step then becomes the integration of the controller to avoid external connections altogether. Thus, in combination with (printed) batteries and WiFi or Bluetooth modules, a flexible and completely self-sufficient system can be developed to offer an all-in-one solution.
