Description
Objectives
  • The objective of this research is to develop new, magnetically-directed, self-assembly approaches to enable complex, three-dimensional structures to be formed in parallel from a heterogeneous mixture of parts of arbitrary size and shape. To achieve this goal, arrays of tiny magnets will be integrated onto the surfaces of batch-fabricated microelectronic components using conventional, low-cost electroplating approaches.
Benefits
  • Self-assembly may reduce the size and cost of electronic devices by eliminating the robotic manipulation and enabling high volumes of parts to be processed in parallel.
