DUAL FLEXIBLE CELLULOSE-BASED MATRIX FOR THE INTEGRATION OF ELECTRONICS AND MICROFLUIDICS

This invention consists of a renewable and biodegradable, flexible, lightweight and miniaturized, cellulose-based, double-layered matrix having a double structure with different degrees of compactness, which is capable of simultaneously integrating microfluidic functions as well as electronic and electrochemical components. One of the layers of the double-layered cellulosic matrix consists of a porous structure, with pores and a hydrophilic affinity which are suitable for fluid flow, ensuring microfluidic functionality. The second layer of the double-layered cellulosic matrix has a highly compact structure, exhibiting an adequate level of surface smoothness to ensure the continuous printing and integration of electronic devices and circuits. The present matrix is applicable in the production of sensors in a wide variety of fields, namely in the fields of medicine, pharmaceutics, food, packaging and distribution, safety, agriculture, the environment and veterinary science.
