We present a novel method to render color patterns using electrolysis applied onto open wet surfaces. By implementing electrodes within a wet object and electrifying them, electrolysis can occur and generate ions. Using color indicators reacting with such ions, we can create a color-forming display. By applying common techniques, such as a printed circuit board, arbitrary patterns can be displayed by computer control. By reversing the polarity of the electrodes and varying the number of ions, it is possible to fade the existing pattern and display a contrasting color. The proposed method does not require moving parts; thus, it is low cost and easy to compact. Also, some foods containing pH-reactive substances can be used as a display medium. Therefore, the proposed method can realize an information display using various objects common in everyday life, such as decor or foods. In this paper, we report on the implementation of the display, possible applications, and feasibility study.

Research was conducted on an electrolysis bubble display intended to be used as an everyday information display device [1]. In contrast, we intuitively assume that the bubbles also hold potential as a method for interactive artwork because of their ephemeral nature. However, the conventional electrolysis bubble display has a low response time and can only realize a low-pixel binary display, limiting the range of expression. This research addresses this challenge and presents two bubble display devices to explore applications to artwork. First, we present "UTAKATA," a tickerlike bubble display, using a running-water channel. Seven electrodes are placed linearly on the channel bed, and they generate text messages using drifting bubble dots. Second, we present the "Bubble Mirror," a water pan with a camera that captures a visitor’s face and displays it using electrolysis bubbles. Facial images with eight grayscale levels are displayed on the water surface using 32 × 32 electrodes.

Research was conducted regarding a display that presents digital information using bubbles. Conventional bubble displays require moving parts, because it is common to use air taken from outside of the water to represent pixels. However, it is difficult to increase the number of pixels at a low cost. We propose a liquid-surface display using pixels of bubble clusters generated from electrolysis, and present the cup-type device <I>BubBowl</I>, which generates a 10×10 pixel dot matrix pattern on the surface of a beverage. Our technique requires neither a gas supply from the outside nor moving parts. Using the proposed electrolysis method, a higher-resolution display can easily be realized using a PCB with a higher density of matrix electrodes. Moreover, the method is simple and practical, and can be utilized in daily life, such as for presenting information using bubbles on the surface of coffee in a cup.
