Biomimetic self-assembly of a functional asymmetrical electronic device

摘要

This paper introduces a biomimetic strategy for the fabrication ofasymmetrical, three-dimensional electronic devices modeled on thefolding of a chain of polypeptide structural motifs into a globularprotein. Millimeter-size polyhedra—patterned with logicdevices, wires, and solder dots—were connected in a linear string byusing flexible wire. On self-assembly, the string folded spontaneouslyinto two domains: one functioned as a ring oscillator, and the otherone as a shift register. This example demonstrates that biomimeticprinciples of design and self-organization can be applied to generatemultifunctional electronic systems of complex, three-dimensionalarchitecture.
