Programmable directed micro-assembly

We aim to develop the capability to rapidly sort, place, and orient micro objects into custom positions and transfer them to a final substrate eventually at costs similar to laser printers assembling toner particles onto paper. We are using programmable directed electrostatic parallel control to move particles from random to ordered patterns. Such a process could enable significantly more heterogeneity, complexity and customizability in material and device integration. We summarize experimental results including assembly and transfer microchip and microbeads at the 1um to 250um size scale, combined with transfer (including roll-roll based) to a final substrate.
