1. A composite microneedle structure based on an integrated circuit chip, comprising:
a microstrip line;
at least one microprobe; and
at least one integrated circuit chip, wherein
the microprobe comprises a hard needle and a soft needle, the soft needle is fixed to an upper surface of the hard needle by a fixed structural member, and the integrated circuit chip is provided at a tail of the microprobe; the integrated circuit chip and the soft needle of the microprobe are fixed to form an electrical connection, and the microstrip line and one end of the integrated circuit chip are fixed to form the electrical connection;
the hard needle is provided with a hard needle tail and at least one hard needle microelectrode formed on the hard needle tail, and the soft needle is provided with a soft needle tail and at least one soft needle microelectrode formed on the soft needle tail; the soft needle tail is fixed to the hard needle tail, and the soft needle microelectrode is fixed to the hard needle microelectrode;
the fixed structural member comprises a first fixing member for fixing the soft needle microelectrode and the hard needle microelectrode, and second fixing members for fixing the soft needle tail and the hard needle tail; and
the second fixing members are a plurality of plug structures provided at intervals along a width direction of the hard needle at the hard needle tail, the plug structure comprises two coaxial cylinders with a larger upper part and a smaller lower part, a plug hole is provided at the soft needle tail corresponding to the plug structure, and a plurality of central symmetrical figures are provided outward along an edge of the plug hole on the soft needle tail, and an upper cylinder diameter of the plug structure is larger than a diameter of the plug hole.
