This chapter describes and updates the development, design, and potential of resistive sensors from smart nanocomposites. Conductive bioPolymer nanoComposites (CPC) are obtained by structuring a network of conductive nanofillers (carbon or metallic) into an insulating biopolymer matrice. Additionally from being helpful to reduce sensors carbon footprint, the use of biopolymers, also offers new functionalities like a higher affinity for polar target molecules, biocompatibility, biodegradability etc. Special attention is paid to the construction of 3D conducting architectures, to their characterisation with the different tools available to image their morphologies at the different scales of observation, and to the innovative electrical properties responsible for their smart behaviours.

Keywords: conductive biopolymers nanocomposite; transducers; vapour sensing; liquid sensing; temperature sensing; strain sensing
