Study of Capacitance in Electrostatic Comb-Drive Actuators

P. Hanasi [1], B. G. Sheeparamatti [1], V. Abbigeri [1], N. Meti [1],
[1] Visvesvaraya Technological University, Belagavi, Karnataka, India

Capacitor is mainly defined as two conducting plates that can hold the opposite charges on it. These plates can be used either as a sensor or an actuator. If the relative distance between the two conductors changes as result of given input, then capacitance values will change. This ... Read More

CAE-Based Design and Optimization of a Plasma Reactor for Hydrocarbon Processing

C. Soares [1], F. A. Cassini [1], N. Padoin [1],
[1] Universidade Federal de Santa Catarina, Florianópolis, SC, Brasil

Plasma reactors can be applied to the conversion of waste, biomass and fuels to synthesis gas (mixture of hydrogen and carbon dioxide) with efficiencies as higher as 90-95% and low energy demand, depending on the design optimization. In this work, a multi-step approach was applied to the ... Read More
