Method for connection to a rigid or flexible device using multifunctional ink

Abstract

The technology is based on a conducting, ferromagnetic ink made from, in an aqueous suspension: conducting nanopolymers, ferromagnetic nanoparticles, an adhesion promoter and optionally, a surfactant and/or stabilizer. The ink is used to form reversible physical and electrical connections between e.g., rigid and flexible devices. In some aspects, the conducting nanopolymers are PEDOT:PSS (poly(3,4-ethylenedioxythiophene) polystyrene sulfonate) nanopolymers and the magnetic nanoparticles are iron oxide nanoparticles. The ink, which may be magnetic, is used to form solid, flexible, ferromagnetic conducting designs or nodes which may also be magnetic. The flexible, ferromagnetic conducting designs or nodes are used to form reversible magnetic electrical connections with devices such as potentiostats and data telemetry devices.
