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 capable of detecting anomalies, in real time, related to the implementation of prosthetic devices inside the human body. The objective is to produce biocompatible and antibacterial electrodes without compromising the electrical conductivity. Along the literature the reader can find a state of the art related to this matter as well as the main results of the physical, chemical, electrical and structural characterization performed in this study.

The present paper deals with a design of a linear stepper motor for biomedical applications. The involved biomedical system is a syringe pump generally used for continuous drug infusion. The syringe pump consists of a linear switched reluctance motor (LSRM) coupled to a syringe plunger. In order to determine the axial force to control the syringe plunger, it was necessary to begin by evaluating the thrust force. The latter constituted the key element for designing the motor. Based on the concept of energy balance, a simplified analytical model was developed to predict the electromagnetic characteristics of the linear switched reluctance motor. The validity of results was ensured by direct comparison with the finite element method (FEM).

This book presents and describes imaging technologies that can be used to study chemical processes and structural interactions in dynamic systems, principally in biomedical systems. The imaging technologies, largely biomedical imaging technologies such as MRT, Fluorescence mapping, raman mapping, nanoESCA, and CARS microscopy, have been selected according to their application range and to the chemical information content of their data. These technologies allow for the analysis and evaluation of delicate biological samples, which must not be disturbed during the profess. Ultimately, this may mean fewer animal lab tests and clinical trials.
