Organic electronics application overview from automotive HMI to X-ray detectors

In order to address requirements in terms of flexibility, lightweight, mechanical robustness, low cost and large area of new electronic devices, hybrid integration bring new opportunities for traditional electronics on flexible substrates. Hybridization consists in merging two categories of electronics: 3D silicon electronics for high speed/frequency digital signal processing and high packaging density (logic, memory) and electronics on foil for interactions with humans and environments where large-area printed technologies are needed (organic multiplexing/reading/amplifying circuits, energy harvesters and batteries, sensors, human-machine interface, displays, antennas). Among the very broad range of printed devices, we will focus this paper on the challenges and opportunities of using TOLAE technologies for 2 applications. The first case will be illustrated by the Horizon 2020 HAPPINESS project (Haptic Printed and Patterned Interfaces for Sensitive Surface), where main goal is to integrate Printed Touch-Sensitive Layers with Haptic Feedback devices made by printing of polymers materials, on a plastic-injected Automotive Dashboards. The second case will be illustrated by the Horizon 2020 LORIX project (Large Organic Robust Imager for XR sensing). The principal means of manufacturing these innovative LORIX sensors is to combine printed organic photodiodes with thin film transistor arrays on glass (traditional silicon electronics) or on flexible, organic TFT-based plastic foils, depending on the targeted application (medical, Non Destructive Testing and security).
