“…The calendaring procedure gave rise to a 10% increase in quality factor of the LC‐circuit used in the sensor design, whereas the resonance frequency decreased somewhat. Flex sensors have been produced by R2R microgravure printing of composites of activated carbon and PVDF at rather low web speeds of 18 cm min −1 on PET films . Stable and consistent changes in electrical resistance were observed when bending samples cut out of the roll up to 120° outwards and inwards.…”

The production of electronic devices using solution based ("wet") deposition technologies has some decisive technical and commercial advantages compared to competing approaches like vacuum based ("dry") manufacturing. Particularly, the potential to scale up production processes to large areas and high volumes by introducing continuous roll-to-roll (R2R) methods on flexible substrates has been the topic of intense studies from both applied research institutes and industry already for some years. Decisive steps forward have been achieved during that time, resulting in the dawn of commercial applications for a number of processes, while additional development work is still needed in some other fields. This review summarizes the work published during the last few years on the R2R printing and wet coating of electronic devices. An overview is presented of the basic operational principles for the most commonly used R2R printing and coating methods and techniques for proper web handling in R2R lines. Then, the most commonly used types of flexible substrate materials are introduced, followed by a review of the work published in the application areas of transparent conductor materials, printed electric connections, light emitting devices, photovoltaic energy generation, printed logic, and sensing.

Wearable sensors are attracting great attentions due to their potential applications in human health monitoring and caring systems. The wide utilization of wearable electronics may cause great burden to the environment, due to the vast contaminants generated in their fabrication and after their usage. Consequently, great efforts are devoted to the eco-friendly strategies for the material and fabrication in wearable sensors. Herein, recent advantages in developing wearable sensors with eco-friendly materials and green manufacturing approaches are reviewed. The functional materials with accessibility, recoverability and degradability have participated in the sensors as substrates, sensing elements and conductors. The fabrication strategies, from facile manual schemes to low-emission automated techniques are also introduced with their merits and demerits. Finally, the existing challenges and future opportunities in this field are summarized.
