Abstract
The present disclosure relates to a piezoresistive ink composition for sensors production. This ink, change linearly their electrical resistivity with an applied deformation and can easily recover when the external applied stress is released. The composition comprises flexible polymers as thermoplastic elastomers from the styrene-butadiene-styrene family (SBS, SEBS or others), nanostructures of carbon or metal, polar solvents and dispersive agents. With this ink, the user can print the sensor with any desired geometry and use different printing techniques, including drop casting, spray, screen and inkjet printing.
