This chapter provides an introduction to a certain class of nonlinear electrokinetic phenomena, where the applied electric field acts on its own induced-charge in an electrolytic solution near a polarizable surface. Many applications are discussed, such as colloidal particle dynamics (induced-charge electrophoresis) and microfluidic mixing and pumping (induced-charge electro-osmosis), while emphasizing the basic physics of each phenomenon. A Standard Model for these situations is introduced and analyzed in simple cases. Similarities and differences are noted with other electrokinetic phenomena, such as classical linear (fixed-charge) electrokinetics in electrolytes and electrohydrodynamics in leaky dielectrics.
