嗅覚ディスプレイの表面音響波アトマイザー効率向上法

Executive Industry Relevance

This method enhances atomization efficiency in surface acoustic wave devices by applying amorphous Teflon coatings, addressing a key challenge in olfactory display technology: residual liquid causing smell persistence. Improved atomization enables more reliable scent delivery in human interface systems, supporting predictive confidence in sensory stimulus generation for virtual reality and neurotechnology applications. The approach provides a reusable surface modification strategy that reduces mechanistic ambiguity in olfactory stimulus presentation.
