Transparent wood, as an innovative type of biomass-based sustainable and environmentally friendly material, exhibits significant advantages in the realm of sustainable materials due to its renewability, biodegradability, and low-carbon manufacturing processes. With its high light transmittance, exceptional mechanical properties, and low thermal conductivity, it presents extensive application prospects in areas such as optoelectronic devices, electromagnetic shielding equipment, and green buildings. However, current research primarily centers on the development of the functional characteristics of transparent wood, while systematic investigations into its technical aesthetic value remain insufficient. This study, grounded in the theoretical framework of technical aesthetics, systematically explores the pathways to realizing the aesthetic value of transparent wood in cross-disciplinary applications from three dimensions: process aesthetics, structural aesthetics, and design aesthetics. The research reveals that transparent wood embodies distinct technical aesthetic characteristics and ecological value in facets such as material processing technology, structural innovation, and visual presentation through the unique integration of optical transparency and natural wood grain. This study not only broadens the application boundaries of transparent wood within the design field but also provides theoretical support and practical guidance for the innovative application of biomass-based materials within the framework of green design.
