Enhancing the longevity and functionality of Ti-Ag dry electrodes for remote bi...
Carvalho, Daniel; Marques, Sandra Mariana Silva; Siqueira, Giorgia; Ferreira, Armando José Barros; Santos, João; Geraldo, DulceThis study aims to evaluate the lifespan of Ti-Ag dry electrodes prepared using flexible polytetrafluoroethylene (PTFE) substrates. Following previous studies, the electrodes were designed to be integrated into wearables for remote electromyography (EMG) monitoring and electrical stimulation (FES) therapy. Four types of Ti-Ag electrodes were prepared by DC magnetron sputtering, using a pure-Ti target doped with...
Evaluation of cell activation promoted by tantalum and tantalum oxide coatings ...
Moreira, Hugo; Barbosa, Augusto Alexandre Costa; Marques, Sandra Mariana Silva; Sampaio, Paula; Carvalho, S.Previous studies have shown both Ta and TaeO to be bioactive, rapidly forming a strongly-bonded surfaceadherent layer of bone-like hydroxyapatite (HAp) when immersed in simulated body fluid (SBF). Consequently, Ta and TaeO coatings are promising for the surface-modification of Ti or stainless steel endodontic endosseous implants, being conducive to a reduction in the risk of developing post-operatory infection ...
Development of multifunctional coatings deposited on polymers based sensors for...
Marques, Sandra Mariana SilvaWithin the framework of materials for biomedical applications, piezoelectric materials are interesting for the development of sensors and actuators in areas such as smart prosthesis, implantable biosensors and biomechanical signal monitoring, among others. However, for the acquisition/application of the electrical signal, suitable electrodes must be produced. Therefore, the aim of this work was the development ...
