A method for manufacturing an electrical conductor includes: depositing a solid metal conductive layer or film on a substrate; depositing a liquid metal on the solid layer; and allowing the liquid metal and the solid layerto alloy by diffusion of the liquid metal into the solid layer or film so as to form a solid conductive layer or film of the alloy; as well as allowing the liquid metal to further infiltrate the alloy so as to form percolating paths and/or droplets of the liquid metal in the the solid conductive layer or film, thus forming a biphasic conductive layer.

Method for manufacturing electrical conductors, and electrical conductors manufactured according to same

A method produces a device adapted to be implanted into the human body for purposes such as neural stimulation, sensing or the like. The method includes: providing a stretchable layer or membrane of an insulating material; forming on the layer or membrane at least one stretchable conductive path; depositing at least one small bolus of a soft and conductive paste or material onto pre-defined areas or portions of the at least one conductive path, and inserting a first end portion of a conductive elementinto the at least one bolus of soft conductive paste or material. A second end portion of the conductive element opposite to the first end portion is not inserted into the at least one bolus.

Synthetic skin for recording and modulating physiological activities

A method produces a conductive paste comprising 15-20% by weight of PDMS and 80-85% by weight of metallic micro-nano particles, wherein the conductive paste is obtained by repeated addition of singular doses of PDMS to a heptane diluted PDMS low viscosity liquid containing the metallic micro-nano particles, wherein the heptane fraction is allowed to evaporate after addition of each of the singular doses of PDMS. A method forms a conductive path on a support layer, wherein the conductive path is encapsulated by an encapsulation layer comprising at least one via through which at least one portion of the conductive path is exposed, the method comprising filling the at least one via with the conductive paste.
