  • Publication number: 20130085359
    Abstract: A flexible microelectrode for detecting neural signals and a method of fabricating the same are disclosed. The method comprises steps: growing a graphene electrode layer on a temporary substrate; growing a flexible substrate on the graphene electrode layer and patterning the flexible substrate; removing the temporary substrate but preserving the graphene electrode layer and the flexible substrate to form an electrode body; and using an insulating layer to wrap the electrode body but exposing a bio-electrode end to contact a living body and detect the signals thereof. The graphene electrode layer features high electric conductivity, high biocompatibility and low noise. The flexible substrate is bendable. Thus is improved the adherence of the skin tissue to the bio-electrode end and decreased the likelihood of skin inflammation.

  • Patent number: 8280479
    Abstract: The present invention discloses a flexible 3D microprobe structure, which comprises at least one probe, a base and a hinge portion. The probe is connected to the base via the hinge portion. The probe forms a bend angle with respect to a normal of the base by attracting the probe through an electrostatic force to make the hinge portion bend with respect to the base, and thus to form a 3D structure having the bend angle. The probe, the base and the hinge portion are made of a flexible polymeric material to reduce the inflammation response of creatures. Further, a fixing element is used to enhance the structural strength of the flexible 3D microprobe structure.
