PhD student in Universidade de Aveiro at the investigation center CICECO-Aveiro institute of materials. I Work in the area(s) of Materials Engineering and Technology with an emphasis on biomedical materials and devices. I'm interested in developing new sensors or actuators with alternative materials such as polysaccharides and the application of new techniques to create functional and smart composites that could be useful for biomedical applications. Currently working with chitosan-based bionanocomposites.

Invention
  1. Demonstrator for piezoelectric bending response: This is a didactic device that allows us to test whether our materials, based on a flexible bionanocomposite containing piezoelectric particles, have piezoelectric properties concerning the direct effect or not. It works at low frequencies from 1Hz to 5 Hz. https://drive.google.com/file/d/1frMFd3wzemhfKEw2_HOC0bFFPhPVFukD/view.. Children and young audience. 2019. Guzman Sierra, Dayana.

  1. Front cover: Flexible Piezoelectric Chitosan and Barium Titanate Biocomposite Films for Sensor Applications. The Front Cover shows a flexible functional biocomposite film composed of chitosan biopolymer and BaTiO3 particles, which was prepared by environmentally benign methodologies. This film is flexible, and its elasticity can be tailored by the addition of BaTiO3 particles. The evidence of piezoelectricity turns this material promising for the design of flexible piezoelectric sensor films.. 2021.
