Abstract
Disclosed are methods and systems of controlling the placement of micro-objects on the surface of a micro-assembler. Control patterns may be used to cause phototransistors or electrodes of the micro-assembler to generate dielectrophoretic (DEP) and electrophoretic (EP) forces which may be used to manipulate, move, position, or orient one or more micro-objects on the surface of the micro-assembler. A set of micro-object may be analyzed. Geometric properties of the set of micro-objects may be identified. The set of micro-objects may be divided into multiple sub-sets of micro-objects based on the one or more geometric properties and one or more control patterns.
Claims20
A method, comprising:
- analyzing a set of micro-objects located on a surface of a micro-assembler, wherein the micro-assembler comprises an array of force generating pixels;
- identifying one or more geometric properties of the set of micro-objects;
- and
- dividing the set of micro-objects into a first subset of micro-objects and a second subset of micro-objects based on the one or more geometric properties and one or more control patterns, wherein the one or more control patterns indicate one or more force patterns on one or more portions of the array of force generating pixels.
An apparatus, comprising:
- a memory configured to store control data;
- a processing device, operatively coupled to the memory, the processing device configured to:
- analyze a set of micro-objects located a surface of a micro-assembler, wherein the micro-assembler comprises an array of force generating pixels;
- identify one or more geometric properties of the set of micro-objects;
- and
- divide the set of micro-objects into a first subset of micro-objects and a second-subset of micro-objects based on the one or more geometric properties and one or more control patterns, wherein the one or more control patterns indicate one or more force patterns on one or more portions of the array of force generating pixels.
A non-transitory computer-readable medium having instruction stored thereon that, when executed by a computer processing device, cause the computer processing device to:
- analyze a set of micro-objects located a surface of a micro-assembler, wherein the micro-assembler comprises an array of force generating pixels;
- identify one or more geometric properties of the set of micro-objects;
- and
- divide the set of micro-objects into a first subset of micro-objects and a second-subset of micro-objects based on the one or more geometric properties and one or more control patterns, wherein the one or more control patterns indicate one or more voltage patterns on one or more portions of the array of force generating pixels.
