This technology utilizes multiple magnetic field coils to apply independent external magnetic fields to the entire or local areas of a human-on-a-chip, enabling the actuation (fluid flow control) and precise positioning (organ docking) of microrobots injected inside.
Existing human-on-a-chip systems rely on constant flow control using external pumps, which makes local precision control difficult and results in complex structural designs and low efficiency when docking artificial or micro-organs at specific locations.
This technology uses independently arranged magnetic field coil units around the chip network to perform local/global magnetic field steering and intensity modulation. By controlling the rotational speed and direction of helical or propeller-type microrobots, it simulates fluid flow or precisely docks microrobots at target locations. Applicable to industrial robots and automation systems, it improves the efficiency of micro-organ positioning and fluid flow within the network, enabling the creation of environments that closely mimic the human body.
This invention was developed with support from the Ministry of Science, ICT and Future Planning for the development of 3D precision magnetic microstructures and cell/drug delivery-based technology.
