    Abstract

    This thesis presents an effort to understand electrokinetic energy conversion systems which are based on motion of ionic charges in micro- and nano-confinements. In particular, both experimentally and theoretically the utilization of different kind of liquids was investigated to convert mechanical to electrical energy in both on-chip and off-chip platforms by applying different forces to drive the fluids: a steady pressure, a periodic pressure and a centrifugal force. The fluids included Newtonian and non-Newtonian fluids. The content of this thesis is constructed as follows: Chapter 1 presents the aim and the outline of the thesis. Chapter 2 presents the fundamental and theoretical aspects of fluid flow in microchannels, introducing both electrostatics and electrokinetics, which concepts are encountered throughout the thesis. Chapter 3 shows the results of experiments when polymers are added to the solution in microchannels for streaming potential energy conversion. In chapter 4 we investigate the potential use of another kind of non-Newtonian fluid, namely a viscoelastic fluid for energy conversion. Chapter 5 shows theory and experiments for ballistic energy conversion systems using the centrifugal force. Chapter 6 offers conclusions based on this work and perspectives for future development.
