A casting coil for a motor assembly, which is formed in a multi-layer structure, includes: a first coil formed to extend in one direction; a second coil bent to extend from an end of the first coil; a third coil bent to extend from an end of the second coil in a direction parallel to the first coil; and a fourth coil bent to extend from an end of the third coil in a direction parallel to the second coil. The first coil, the second coil, the third coil, and the fourth coil form one layer so that a hollow multi-layer structure is formed. A larger magnetic field can be formed by securing a slot filling factor of 50% or more of a stator in the same motor package.

Disclosed are a microneedle patch and a method for fabricating the microneedle patch. The microneedle patch includes a base layer including a mesh structure or auxetic materials having a negative Poisson's ratio, and a microneedle array disposed on the base layer. The method includes forming a base layer including a mesh structure or auxetic materials having a negative Poisson's ratio, and forming a microneedle array on the base layer.
