1. A neural network interface (NEI) device for stimulating a cerebral nerve of a patient to control abnormal motor and sensory functions of a brain of the patient, the NEI device comprising: a hat module configured for placement over a head of the patient, wherein the hat module is configured to wirelessly supply power; and a deep brain monitoring and stimulation (DBMS) module including: a thin film configured to be fixed between a skull and a scalp of the patient; a probe pin device (PPD) having a shape of a pin, having a head portion that is directly attached to a lower surface of the thin film, and configured to be implanted through the skull under the scalp of the patient to thereby contact the cerebral nerve of the patient; and a power and signal processor disposed on the thin film and configured to wirelessly receive the power from the hat module, wirelessly transmit nervous system data monitored by the PPD to the hat module, and wirelessly receive a control command signal from the hat module to thereby control the DBMS module according to the nervous system data; wherein: (a) the hat module is configured to generate a rotating magnetic field toward the DBMS module and the DBMS module is configured to be driven using induced power which is generated by a magnetic induction which is generated by the rotating magnetic field; or (b) the hat module is configured to transmit a microwave to the DBMS module and the DBMS module is configured to receive the microwave, transform the microwave into direct current (DC) power, and be driven by the DC power.
