AB  - Flexible multiferroic composite films are perspective materials for sensors, actuators and similar com-ponents of wearable and stretchable devices. Here we present the study of functional properties of flexible composites prepared by embedding nickel zinc ferrite and barium titanate powder into polyvinylidene fluo-ride (PVDF) polymer optimizing the ratio of polymer and fillers to get the best flexibility and functionality. ATR-FTIR analysis revealed that hot pressing of the flexible films causeda transformation of about 38% of the electro-inactive PVDF α phase into electrically active β and γ phases. Broadband dielectric spectroscopy revealed two relaxation processes responsible for PVDF and space charge relaxations. Activation energies of  both  processes  and  the  freezing  temperature  of  PVDF  to  the  glass  phase  were  estimated  for  all  films.  Ferroelectric  measurements  have  shown  unsaturated  hysteresis  loops  for  all  samples,  although  the  clear  dependence of the amount of the electrically active phase on polarization values of composites is visible.
