/ ELECTROMAGNETIC DRIVE SYSTEM FOR MEDICAL MICRO/NANO ROBOT USING SUPERCONDUCTING ELECTROMAGNET

摘要

The present invention relates to an electromagnetic driving apparatus for a medical micro/nano robot, which magnetizes a micro/nano robot inserted in the body and controls driving of the micro/nano robot by electromagnetic. The apparatus comprises: an electromagnet part for generating a magnetic field in a direction of the micro/nano robot by including a coil for generating a magnetic field in an axial direction and a magnetic core for focusing a magnetic flux to the coil, wherein the coil comprises a high-temperature superconducting coil showing a superconducting phenomenon at a critical temperature of 100 K or higher; and a cooling unit for cooling the high-temperature superconducting coil of the electromagnet part to a temperature below the critical temperature to maintain the superconducting state of the electromagnet part. The present invention can solve the problem of the power loss and the reduction of intensity of the magnetic field due to the heat generation of a conventional copper coil electromagnet.
