Microcoil element, array-type microcoil element and device

An array-type microcoil element, comprising:

• multiple microcoil elements, in which each of microcoils is energized to generate a magnetic field equivalent to a multiturn coil;
• and the array-type microcoil element is used to generate an equivalent magnetic field through the energized multiple microcoil elements, wherein each of the microcoil elements includes:
• a wiring layer having continuous multiple metal line segments that is formed of multiple loops of continuous multiple metal line segments around a starting point, and every metal line segment including a first electrode end and a second electrode end, wherein the starting point is a first electrode of the microcoil element, and an end of the continuous multiple metal line segments is a second electrode of the microcoil element;
• and
• an electrode layer having at least one first electrode zone and at least one second electrode zone, wherein the at least one first electrode zone is used to converge the first electrode ends of the multiple metal line segments, and the at least one second electrode zone is used to converge the second electrode ends of the multiple metal line segments.

A microcoil device, comprising:

• at least one magnetic component constituted of one or more microcoil elements, wherein the magnetic component is a single microcoil element or an array-type microcoil element;
• and
• a circuit board connected with a power supply for supplying power to the at least one magnetic component;
• wherein the microcoil element includes:
• a wiring layer having continuous multiple metal line segments that is formed of multiple loops of continuous multiple metal line segments around a starting point, and every metal line segment including a first electrode end and a second electrode end, wherein the starting point is a first electrode of the microcoil element, and an end of the continuous multiple metal line segments is a second electrode of the microcoil element;
• and
• an electrode layer having at least one first electrode zone and at least one second electrode zone, wherein the at least one first electrode zone is used to converge the first electrode ends of the multiple metal line segments, and the at least one second electrode zone is used to converge the second electrode ends of the multiple metal line segments.
