Abstract

Last year we demonstrated the microjet ballistic energy conversion system[l]. Here we show that the efficiency of such a system can be further improved by gate control. With gate control the electrical current generation is enhanced a hundred times with respect to the current generated from the zeta potential. A maximum efficiency of 48% is obtained using a 30μm pore. Energy was still lost on viscous flow, surface production and air friction. The higher droplet charge density using gate control can also be used to decreases the required target voltage. Thus a 12% efficiency was achieved with 500V target voltage using a 10μm pore and voltage gating.
