Abstract
This paper describes the use of a nonphotolithographic technique-micro contact printing-to fabricate a concentric cylindrical microtransforme r having an outer diameter of similar to 350 mu m. For frequencies of up to 20 kHz, this microtransformer has a high coupling coefficient (> 0.9). At higher frequencies, properties of the ferromagnetic material used in the construction of the microtransformer limit performance.
