• Abstract

  Nowadays, it has been a great demand for intelligent materials that on the action of an external stimulus have their physical and/or chemical properties modified as response. Within this class, it highlights the piezoelectric materials, which under the action of an external stimulus produce an electric current. Aiming at this theme, the present project aims to develop new polymer/ferroele…

• Abstract

  Nowadays, the search for intelligent materials that on the action of an external stimulus has its physical and / or chemical properties modified in response has been great. Within this class, we highlight the piezoelectric materials, which under the action of an external stimulus produce an electric current. This project aims at the development of a new piezoelectric three-phase biopolyme…

  Evaluation of the synergistic effect in Biopolymer/Conductive Nanoparticles/PZT three-phase piezoelectric composites, for sensors application, BP.IC

• Abstract

  Materials capable of significantly altering one or more of their properties (mechanical, thermal, optical or electrical) under the action of an external mechanical stimulus are classified as intelligent materials. Due to their unique characteristics, these materials are perfect for sensor development. Among these materials, we highlight piezoelectric materials, which produce an electric c…

• Abstract

  The present project has the objective to evaluate the dispersion of a conductive phase (carbon black or carbon nanotube) in the piezoelectric, dielectric and electrical properties polymer/ferroelectric ceramic piezoelectric composite with 1-3 connectivity aiming their use as energy harvesting. In order to obtain the composites, two polymer matrices will be used as support for the ceramic …

• Abstract

  Biomaterials are defined as substances or mixtures (natural or artificial) that can replace, repair, or treat biological systems partially or totally. Natural polymers have garnered special attention within the class of biomaterials owing to their biocompatibility and low cytotoxicity. Natural rubber (NR) extracted from Hevea brasiliensis has great potential for biomedical applications by…
