A Design Transformation Framework for Biologically Processed Materials in Biodesign

抄録

This study examines how biologically processed materials in biodesign are transformed into final design outcomes, with a focus on what forms of materiality remain from biological processes and how such residual materiality is organized into design experience. While existing discussions of biodesign have often focused on living materials, sustainable alternatives, or biological fabrication technologies, this study attends to the residual materiality that remains in design outcomes after biological activity has ceased, including color, texture, structure, membranes, fibers, and porosity. To this end, the study reviews prior research on biodesign, material experience, material biography, and the material aesthetics of heterogeneity and temporality. It then compares twenty contemporary biodesign cases in terms of their biological processes, final states of application, residual materiality, and modes of design transformation. Among these cases, Totomoxtle, Oki Naganode, Mycelium Chair, Project Coelicolor, and Microbial Textile Platform are selected as representative cases for in-depth analysis. The analysis identifies four modes of design transformation in biologically processed materials: the materialization of formation conditions, the sensory articulation of process traces, the persistence of temporality after inactivation, and the experiential organization of residual materiality. By proposing a framework that explains the relationship between biological processes, residual materiality, and design experience, this study offers a perspective for interpreting biodesign materials as design materials in which the conditions and traces of processes are transformed into experience.
