    • Desenvolupament sostenible i transferència de coneixemenet: el cas de la UPC 

      Losantos Viñolas, Pedro (Centre per a la Sostenibilitat, 2009-07-09)
      Conference report
      Open Access
      La recerca sobre el desenvolupament sostenible -tal i com fa palesa la pròpia proposta de temes d’aquest congrés- tracta sovint del medi ambient, de la utilització de recursos naturals, d’arquitectura, de cooperació, de ...
    • Improvement of the quality factor of RF integrated inductors by layout optimization 

      López-Villegas, José M.; Samitier, Josep; Cané, Carles; Losantos Viñolas, Pedro; Bausells, J. (IEEE Microwave Theory and Techniques Society, 2000-01-01)
      Article
      Restricted access - publisher's policy
      A systematic method to improve the quality (Q) factor of RF integrated inductors is presented in this paper. The proposed method is based on the layout optimization to minimize the series resistance of the inductor coil, ...
    • Magnetic-field sensor based on a thin-film SOI transistor 

      Losantos Viñolas, Pedro; Cané, Carles; Flandre, Denis; Eggermont, Jean-Paul (1998-01-01)
      Article
      Restricted access - publisher's policy
      This paper presents a magnetic sensor on thin-film SOI-SIMOX that takes advantage of a previous bipolar structure, the VCBM (voltage-controlled bipolar MOS transistor) to improve magnetic response with low power consumption. ...
    • Micromachined optical fiber current sensor 

      Heredero, R.L.; Fernández de Caleya, Ramón; Guerrero, Héctor; Losantos Viñolas, Pedro; Acero, M.C.; Esteve, J. (1999-10-01)
      Article
      Open Access
      We describe a micromachined optical fiber current sensor. The sensing element consists of a squared silicon membrane (8 mm long and 20 μm thick) that has a cylindrical permanent magnet (NdFeB alloy, 3-mm diameter, 1.5 mm ...
    • Multilayer ISFET membranes for microsystems applications 

      Cané, Carles; Götz, A.; Merlos, A.; Gràcia, I.; Errachid, Abdelhamid; Losantos Viñolas, Pedro; Lora-Tamayo, E. (1996-09-01)
      Article
      Restricted access - publisher's policy
      The fabrication of microsystems in which chemical measurements play a role make the on-chip combination of chemical sensors and signal processing circuitry highly desirable. Chemical sensors use sensitive layers which are ...
    • The use of ferrofluids in micromechanics 

      Pérez Castillejos, R.; Plaza, J.A.; Esteve, J.; Losantos Viñolas, Pedro; Acero, M.C.; Cané, Carles; Serra-Mestres, F. (2000-08-01)
      Article
      Restricted access - publisher's policy
      An introduction to ferrofluids in MEMS applications is presented. Ferrofluids are fluids with magnetic properties. By applying a magnetic field, the balance of forces within the ferrofluid is varied so that the magnetic ...
