The steady increase in electronic properties of polymer thin films made organic electronics feasible to high-frequency operation, suggesting a possible and appealing scenario where lightweight, cost-effective, and conformable electronics can integrate both sensing and radio-frequency RF transmitting functionalities, which are the key to unlock pervasive networks of distributed sensors revolutionizing human–environment interaction. However, severe limitations in terms of device performance at RF, when large-area and scalable fabrication techniques and solution-processed polymers are employed, have largely precluded the achievement of such an appealing goal and achieving wireless operation in printed organic electronics has been a long chased milestone. PME group in the last few years has deeply investigated such unexplored path through the European Research Council project “High-frequency printed and direct-written organic-hybrid integrated circuits” (HEROIC). 
PME has recently set the record in operational frequency for organic transistors, achieving a frequency of transition of 160 MHz, with devices based on solution processed polymers and laser-sintered electrodes.
