Systems and methods for forming micro-object assemblies

摘要

A xerographic micro-assembler system, method and apparatus that includes a sorting unit that is adapted to receive a plurality of micro-objects. The micro-objects can also be sorted and oriented on the sorting unit and then transferred to a substrate. The system, method and apparatus can also include a device for detecting errors in at least one of the micro-objects on the sorting unit and a protection means for preventing an improper micro-object from being transferred to the substrate. The system, method and apparatus can also include an organized micro-object feeder assembly that can transfer at least one of a plurality of micro-objects to the sorting unit or directly to the substrate.

1. A system for forming a micro-assembly, comprising:
a wave pattern encoded sorting unit including at least one photoconductor disposed and adapted to receive a plurality of micro-objects on a surface thereof, and an electrode disposed adjacent to the photoconductor for generating an alternating voltage on said surface; an optical pattern writer for optically charging the wave pattern encoded sorting unit by directing light onto the surface of the photoconductor, wherein the optical pattern writer being synchronized with the alternating voltage to form a dynamic reconfigurable field on the surface of the photoconductor that attracts said micro-objects.
