      Article
      Accés obert
      Flexible symmetric supercapacitor prototypes composed of electrodes that were prepared by polymerizing poly(hydroxymethyl-3,4-ethylenedioxythiophene) inside a poly-¿-glutamic acid (¿PGA) biohydrogel matrix, previously ...

    • Self-healable and eco-friendly hydrogels for flexible supercapacitors 

      Babeli Aguilera, Ismael; Ruano Torres, Guillem; Puiggalí Jou, Anna; Ginebra Molins, Maria Pau; Alemán Llansó, Carlos; García Torres, José Manuel (Wiley (John Wiley & Sons), 2021-03-11)
      Article
      Accés obert
      One limitation of wearable electronics, and at the same time a challenge, is the lack of energy storage devices with multiple functionalities produced using clean and environmental-friendly strategies. Here, a multifunctional ...

    • Study on storage energy devices: supercapacitors, a green alternative 

      Rancaño Fernandez, Ariadna (Universitat Politècnica de Catalunya, 2011-11-03)
      Projecte Final de Màster Oficial
      Accés obert
      Nowadays, it is increasingly common to hear about environmental issues. This fact keep us to continually try to improve energy optimization, either through new storage devices that pollute less or improvements in the ...

    • Supercapacitor impedance in time and frequency domains 

      Cuadras Tomàs, Àngel; Ovejas Benedicto, Victòria Júlia (IEEE, 2012)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      In this contribution we estimate supercapacitor impedance from temporal measurements from two points of view: i) fitting a predefined model to the temporal data and ii) transform time domain analysis to frequency domain ...
