Functional electronic systems have been screen- or inkjet-printed on different plastic substrates, including polyethylene terephthalate, polycarbonate and polycarbonate/acrylonitrile butadiene styrene blends. Mutual capacitive sensors were designed and printed on flexible substrates and the capacitive response and functionality of the printed sensor with integrated passive electronic components was demonstrated. The applicability of both, inkjet printing and screen printing for the development of such capacitive sensors was evaluated. The influence of the substrate, sensor design and the printing technique parameters on both printability and functionality are discussed. Further, a flexible illumination system was developed, where the printed circuit was combined with surface mounted light emitting diodes and integrated circuits. Finally, the developed capacitive sensors and the illumination system were connected to each other to demonstrate the connectivity and interoperability of the different printed circuit components.

功能电子系统已经丝网印刷或喷墨印刷在不同的塑料基材上，包括聚对苯二甲酸乙二醇酯，聚碳酸酯和聚碳酸酯/丙烯腈丁二烯苯乙烯共混物。设计了互电容传感器并将其印刷在柔性基板上，并演示了带有集成无源电子组件的印刷传感器的电容响应和功能。评估了喷墨印刷和丝网印刷对于此类电容式传感器开发的适用性。讨论了基材，传感器设计和印刷技术参数对可印刷性和功能性的影响。此外，开发了一种柔性照明系统，其中印刷电路与表面安装的发光二极管和集成电路结合在一起。最后，
