A method for fabricating an electrochemical sensor material includes positioning sheets of molded graphene nanoplatelets on each side of a proton exchange membrane and integrating graphene nanoplatelets into regions of the proton exchange membrane adjacent its surfaces by applying heat to increase the temperature of the proton exchange membrane to its glass transition temperature and applying compressive pressure to press a portion of each sheet of molded graphene nanoplatelets into the softened polymeric material of the proton exchange membrane. Following application of heat and pressure, the proton exchange membrane is cooled and excess graphene material is exfoliated. Electrochemical sensor components are cut from the material and electrochemical devices and systems are constructed therefrom.

The present invention describes a method and a machine for the formation of a capsule (100) for producing beverages in which the capsule (100) comprises a pleated capsule body (101) and a reinforcing element (102). The method comprises the following steps: a step of forming the pleated capsule body (101) of the capsule (100) in a first station (110); a step of supplying the reinforcing element (102) in a second station (111) different from the first station (110); a step of transporting the pleated capsule body (101) from the first station (110) to the second station (111); a step of insertion in the second station of the pleated capsule body (101) in the reinforcing element (102); a step of coupling between the pleated capsule body (101) and the reinforcing element (102) in the second station (111).
