This book illustrate the study and development of bioactive electrodes to apply in piezoelectric sensors for biomedical applications, respectively in internal orthopedic prosthesis. These electrodes are composed by Titanium doped with Silver and Gold. Titanium, being widely known for its biocompatibility, serves as electrical conductor, Silver acts as antibacterial agent and Gold is used to induce Silver ionization due to the formation of a galvanic pair, once the antibacterial effect is achieved by Silver ions. These electrodes were deposited on piezoelectric polymer, assembling a sensor...
