Inkantatory Paper : 銀ナノ粒子インクを用いた発熱制御に基づく発色式紙面インタフェース(<特集>デジタルファブリケーションとVR) Inkantatory Paper : Color-forming Paper Interface Based on Temperature Control Using Silver Conductive Ink(<Special Issue>Digital Fabrication and VR)
We propose a combination of multiple functional inks, including conductive silver ink, thermo-chromic ink, and regular inkjet ink, for a novel paper-based interface called Inkantatory Paper that can dynamically change the color of its printed pattern. Constructed with off-the-shelf inkjet printing using silver conductive ink, our system enables users to fabricate thin, flat, flexible, and low-cost interactive paper. In addition, we realize thermal feedback control by using a thermo sensor. We evaluated the characteristics of the conductive silver ink as a heating system for the thermo-chromic ink and created applications demonstrating the usability of the system.
