Wearable three-dimensional auricular multi-point bio-signal acquisition, health status monitoring, and bio-stimulation device

A three-dimensional printed, personalized auricular multi- point bio-signal acquisition, heath status monitoring, and bio-stimulation device comprising:

• an artificial ear model configured to be complementary morphologically to a wearer's outer ear comprising a plurality of 3D printable materials forming a body prepared according to multiple geometrically pre-marked and pre-sampled point locations by 3D scanning, and one or more sensing and simulating electrodes by 3D printing with a plurality of bio-signal sensing ends that are exposed on a surface of the artificial ear model that is proximal to a surface of the wearer's outer ear where the majority of auricular points of human body is located;
• at least a data acquisition unit for independently and simultaneously collecting real-time bio-signals detected by the plurality of sensing and stimulating electrodes from the multiple auricular points of the wearer's outer ear and processed by an automatic 3D contour mapping user interface.
