Self-assembly apparatus, method for self-assembling devices, and method for assembling thermoelectric devices

Provided is a self-assembly apparatus for assembling a plurality of devices with a predetermined aspect ratio. The self-assembly apparatus includes a guiding element, a vibration device, and a magnetic field inducing device. The guiding element has a mesh structure. The vibrating device is connected to the guiding element so as to vibrate the guiding element. The magnetic field inducing device is disposed under the guiding element and generates a time-varying magnetic field so as to rotate each of the devices. By the collective effect of the vibration of the guiding element, the time-varying magnetic field, and the self-gravity of each of the devices, each of the magnetic devices is positioned, via the mesh structure, on a plate between the guiding element and the magnetic field inducing device.
