Multiplanar planar electromagnetic array
| DWPI Title: Multiplanar electromagnetic array, comprises first-layer electromagnetic coil, second-layer electromagnetic coil, third-layer electromagnetic coil, programable microactuator, where the programable microactuator generates spatiotemporal magnetic field by sequentially energizing electromagnetic coils |
| Abstract: A multiplanar electromagnetic array is disclosed herein, where the array includes a first electromagnetic coil in a first plane, a second electromagnetic coil in a second plane, and a third electromagnetic coil in a third plane. A microactuator is configured to energize electromagnetic coils in the array in sequence, thereby forming a moving electromagnetic field that moves a permanent magnet positioned above the multiplanar electromagnetic array. Movement of the permanent magnet effectuates desired movement of a bead that is in a channel of an immunoassay device. |
| Use: Multiplanar electromagnetic array. |
| Novelty: Multiplanar electromagnetic array comprises: (a) a first-layer electromagnetic coil located in a first plane; (b) a second-layer electromagnetic coil located in a second plane, where the second-layer electromagnetic coil is partially overlapping the first-layer electromagnetic coil and is offset from the first-layer electromagnetic coil in X and Y directions; (c) a third-layer electromagnetic coil located in a third plane, where the third-layer electromagnetic coil is partially overlapping the second-layer electromagnetic coil and is offset from the second-layer electromagnetic coil in the Y-direction, where the third-layer electromagnetic coil and the second-layer electromagnetic coil are aligned in the X-direction; the third-layer electromagnetic coil is partially overlapping the first-layer electromagnetic coil and is offset from the first-layer electromagnetic coil in the X-direction, and the third-layer electromagnet. |
