In this paper, we show how to combine microfluidics and feedback control to independently steer multiple particles with micrometer accuracy in two spatial dimensions. The particles are steered by creating a fluid flow that carries all the particles from where they are to where they should be at each time step. Our control loop comprises sensing,(More)
We show how it is possible to combine micro-fluidics and feedback control (sense, compare, and apply corrective actuation) to steer many particles at once. The particles are steered by creating a spatially complex and time-varying fluid flow that carries all particles along their desired trajectories. We demonstrated experimental results for steering of a(More)
Electrowetting on dielectric (EWOD) micro-fluidic systems use electrodes to effectively locally change the surface tension properties of liquid droplets and to thereby move, split, merge, and mix liquids inside microscale devices. The system is aimed at creating a laboratory on a chip: a miniaturized device that can carry out all the tasks that are(More)
All PV systems have cells or groups of cells connected in series in order to build up voltage and minimise current. Because current is almost linearly dependent on the incident light, the current in a string of identical solar cells will be limited by the cell with the least illumination. It is therefore important to achieve a flux profile as uniform as(More)
