    • A combination of a vibrational electromagnetic energy harvester and a giant magnetoimpedance (GMI) sensor 

      Beato López, Juan Jesús Upna; Royo, Isaac Upna; Algueta-Miguel, Jose M. Upna; Gómez Polo, Cristina (MDPI, 2020)   Artículo / Artikulua  OpenAccess
      An energy harvesting device combined with a giant magnetoimpedance (GMI) sensor is presented to analyze low frequency vibrating systems. An electromagnetic harvester based on magnetic levitation is proposed for the electric ...
    • Micrometric non-contact position magnetoimpedance sensor 

      Beato López, Juan Jesús Upna; Royo, Isaac Upna; Gómez Polo, Cristina Upna (Elsevier, 2018)   Artículo / Artikulua  OpenAccess
      In this work a sensitive micrometric non-contact position sensor based on the Giant MagnetoImpedance effect (GMI) is analyzed. A nearly zero magnetostrictive CoFeSiBCr wire was employed as sensor nucleus. The sensing ...
    • Thrust actuator with passive restoration force for wide gap magnetic bearings 

      Royo, Isaac Upna; Beato López, Juan Jesús Upna; Castellano Aldave J. C.; Gómez Polo, Cristina Upna (Elsevier, 2019)   Artículo / Artikulua
      Active thrust magnetic bearings provide an axial force to balance the moving parts of machines. However, most devices produce null or unbalancing passive forces. Furthermore, reported designs usually feature very small ...
