Front Cover: Flexible Piezoelectric Chitosan and Barium Titanate Biocomposite Films for Sensor Applications (Eur. J. Inorg. Chem. 9/2021)

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 dielectric permittivity increases with the barium titanate content. The evidence of piezoelectricity turns this material promising for the design of flexible piezoelectric sensor films. More information can be found in the Full Paper by P. Ferreira and co‐workers.
