    Magnetic behavior of polymer-based scanners is studied in detail with emphasis on a new magnetic actuator model and dc deflection experiments. A 30-mu m-thick permalloy sheet is plated on a polymer cantilever scanner and actuated using an external coil. Mechanical and magnetic modeling of the device and experimental results are presented. Shape anisotropy of the thin, soft magnetic film is explored for push and pull operation in different configurations. A new magnetic actuator model is developed based on the distributed point-by-point calculation of the magnetostatic moments and forces across the film surface. This effort helps one to obtain generic equations for magnetic force and torque without limiting the use of the model to the case where magnetic material is assumed to be fully saturated. Two-dimensional (2-D) scanning utilizing the orthogonal modes of the scanner, using only one actuation coil is presented.

    Polymer magnetic scanners for bar code applications
    (Elsevier Science Sa, 2007) Yalçınkaya, Arda Deniz; Department of Electrical and Electronics Engineering; N/A; Ürey, Hakan; Ergeneman, Olgaç; Faculty Member; Master Student; Department of Electrical and Electronics Engineering; College of Engineering; Graduate School of Sciences and Engineering; 8579; N/A
    Resonant mode polymer-based electromagnetic scanners are developed for barcode reading applications. The electromagnetic scanner consists of a mirror suspended by a polymer cantilever beam, a permalloy sheet attached to the mirror, and an external coil to generate the driving magnetic field. The simple fabrication process involves polymer molding and electroplating of magnetic material, yielding inexpensive devices suitable for high volume manufacturing. Mechanical and magnetic modeling of the device as well as analytical, numerical and experimental results are presented. A barcode reading system is demonstrated successfully using this inexpensive, easy to manufacture scanner. Fabricated cantilever scanners achieve an optical theta-D product of 123 degrees mm at 56.5 Hz, consuming an actuation power of 168 mW. 2D actuation of the cantilever scanners is also demonstrated.
