This paper describes the measurement of the electric wind phenomenon via using Global Imaging methods. Electric wind can be described as movement of the air generated by free ions metal object (in our case electrodes) which are powered by high voltage. This physical phenomena is a vital part of the AC electrospinning technology that was developed at Technical university of Liberec. We visualize and measure electric wind velocities around vicinity of the electrode. Measurements are done with our custom build setups. Both high voltage power source system and chamber are original pieces of equipment. We substitute nanofibrous sleeve, the product of the AC electrospinning with various electrically neutral monodispersed particles. The differences in particles are mainly conductivity and polarizability. Particles are accelerated by movement of the air and then lightened by laser and recorded on high speed camera. The outputs of our measurements are vector maps that clearly describe movements of the air around electrode.Keywords: AC nanofibers, Particle tracking velocimetry (PIV), ionic wind
