Low-cost paper-based sensors for strain-induced applications.

The paper presents the work done on the fabrication and implementation of low-cost, dip-coated sensors for tactile applications. Graphene nanoparticles and tissue papers were used as raw materials to form the sensors. The prototypes were encapsulated with polydimethylsiloxane (PDMS) to make them tear and wear resistant. Graphene has been one of the pioneering materials in forming flexible, conductive prototypes. The prototypes were formed using dip-coating process, which has been one widely used synthesis technique due to advantages like customization of layer thickness, quick batch production and ability to process a wide range of nanomaterials and polymers. The results shown here provides a proof-of-concept and forms a podium to use these sensors for multiple strain-induced applications.
