Textbook in PDF format This collection on materials and technologies is the first of a three-volume handbook on all aspects of paper-based devices from synthesis of nanocellulose and paper fabrication to discussion of features of fabrication of various flexible sensors and electronic devices on paper substrates. Subsequent volumes address sensors and bio- and environment engineering, electronics, and energy technologies. The books also present a comprehensive and detailed analysis of all aspects of applications of these sensors and devices in environment monitoring, biomedicine, healthcare, agriculture, the food industry, energy, electronics, optoelectronics, and other domains. Paper-based bioengineering and environment engineering are also discussed in detail in these books. The books enable the reader to understand the present status of paper-based sensors and devices and the role of paper in the development of new generation of sensors and electronic devices for various purposes with enhanced efficiency
