High-Resolution Self-Assembly of Functional Materials and Microscale Devices via Selective Plasma Induced Surface Energy Programming.

ABSTRACT: Current technologies preclude effective and efficient self-assembly of heterogeneous arrangements of functional materials between 10^-1 and 10^-5 m. Consequently, their fabrication is dominated by methods of direct material manipulation, which struggle to meet the designers' demands regarding resolution, material freedom, production time, and cost. A two-step, computer-controlled is presented, multi-material self-assembly technique that allows heterogenous patterns of several centimeters with features down to 12.5 µm in size. First, a micro plasma jet selectively programs the surface energy of a polydimethylsiloxane substrate through localized chemical functionalization. Second, polar fluids containing functional materials are simplistically introduced which then self-a
