International Classification:

H02K 41/02
H02P 8/00

US Classification:

310 1205, 318696, 310 1221

Abstract:

A system has a circuit substrate having conductive traces in a first layer of the substrate, the traces arranged in independent zones, a diamagnetic layer residing on a surface of the circuit substrate, at least two manipulators residing adjacent the magnetic layer, the manipulators being moveable within the zones, the manipulators being magnetic and controllable through magnetic fields, and a controller electrically coupled to the traces arranged to produce signals to generate magnetic fields.

Abstract:

A method of propelling a magnetic manipulator above a circuit substrate includes arranging a magnetic manipulator on a diamagnetic layer on a surface of the circuit substrate, generating drive signals using a controller, and applying the drive signals to at least two conductive traces arranged in the circuit substrate below the diamagnetic layer. A circuit substrate to control movement of a magnetic manipulator has a diamagnetic layer on a surface of the substrate, and conductive traces arranged under the diamagnetic layer, the conductive traces arranged in a parallel line pattern in at least two separate layers.
