1. Self-Tuning Multimodal Piezoelectric Shunt Damping
Piezoelectric shunt damping is a well known structural vibration control technique that consists in connecting an electrical circuit to a piezoelectric transducer attached to the structure. In the case of a resonant shunt, the network consisting of an inductor-resistor network when combined with the capacitive nature of the piezoelectric transducer impedance

2. INFLUENCE OF THE OPERATION PRESSURE ON THE PERFORMANCE OF A DIFFERENCIAL PRESSURE TRANSMITTER: A METROLOGICAL ANALYSIS / INFLUÊNCIA DA PRESSÃO DE OPERAÇÃO NO DESEMPENHO DE TRANSMISSORES DIFERENCIAIS DE PRESSÃO: UMA ANÁLISE METROLÓGICA
Nesta dissertação é realizada uma análise experimental da influência da pressão estática na medição de pressão diferencial com transmissores eletrônicos, dotados de sensores capacitivos ou sensores de silício ressonante, cuja tecnologia é amplamente difundida nos dias atuais por serem de elevada repetitividade, reprodutibilidade, exatidão e bai

3. CARACTERIZAÇÃO DE ATUADORES BASEADOS EM MÚSCULOS ARTIFICIAIS POLIMÉRICOS POR EFEITO CAPACITIVO / CHARACTERIZATION OF ACTUATORS BASED ON POLYMERIC ARTIFICIAL MUSCLES WITH CAPACITIVE EFFECT
It is well known the needs of finding new technologies for robotic systems actuations, with the same efficiency of the natural muscles. The common actuators have better agility and force when compared to natural muscles, but the dimensions and weight are bigger and for that the demand of energy necessary for the actuation is higher. Smaller and cheaper robot

4. Desenvolvimento de um sistema de tomografia capacitiva para processos multifasicos
This work presents the development of a capacitive tomography system to the study of multiphase processes. The research starts with a literature review about tomography. A finite element analysis is accomplished to offer data for the optimization of the capacitance sensor and for a comparative analysis with the experimental results. The image reconstruction
