Claim 10:
11. A method for making the device of claim 1, the method comprising:
providing a reverse auricular mold comprising preparing a three-dimensional artificial ear body by 3D molding to have an ear impression shaping conformably with human auricle, mixing at least one bio-compatible polymer with at least one catalyzer uniformly to obtain a mixture, and filling up the three-dimensional artificial ear body with the mixture until the mixture is solidified in order to form a body of the reverse auricular mold;
scanning a three-dimensional geometry of the human auricle comprising using a structural-light-based three-dimensional scanning to generate a point cloud for subsequent three-dimensional geometrical configuration of the reverse auricular mold;
subjecting the reverse auricular mold simultaneously to a 3D printing device incorporating at least a flexible elastomer and a conductive material so as to generate one or more sensing and stimulating electrodes with a sensing end of each of the one or more electrodes that is exposed at the surface which is proximal to the surface of the wearer's outer ear where the majority of the auricular points is located such that a mechanically stable whilst flexible electrode-human skin interface is formed.
