Abstract
Micro-windmills, micro-systems including micro-windmills, and methods of forming the same are described. The micro-systems with a micro-windmill are configured to withstand wind pressures and environmental conditions and can be used for various applications.
Claims9
A micro-system, comprising:
- a micro-windmill, comprising:
- a substrate;
- and
- a fan comprising a plurality of structural layers deposit and patterned on the substrate, the fan comprising:
- a hub;
- and
- a plurality of vanes attached to the hub;
- wherein each of the hub and the plurality of vanes comprises at least one of the plurality of structural layers;
- and
- wherein the fan is configured to rotate in a first plane relative to the substrate;
- and the substrate defines a second plane, wherein the first plane and the second plane are substantially parallel to one another;
- and
- a coil;
- wherein the fan is formed from a ferromagnetic material and each vane is magnetized;
- wherein neighboring vanes have opposite polarities;
- and
- wherein the coil is configured to be rotated to be positioned such that:
- a third plane defined by a loop of the coil is orthogonal to the first plane;
- and
- the third plane intersects the hub;
- and
- wherein rotation of the fan creates an alternating magnetic field at the coil.
