• Research Motivation and Related Work:
  • This study is inspired by the resist-blasting technique, originally used for ceramic decoration.
  • The motivation lies in combining the value of traditional craftsmanship with novel interactive circuit design, exploring how resist-blasting can create functional yet aesthetically pleasing ceramic interactive interfaces.

Solution

• Method or Solution:
  • Introduce the resist-blasting technique to etch conductive traces on ceramic surfaces.
  • Apply conductive ink to these etched traces, enhancing the interactive functionality of ceramic circuits.
  • Develop a systematic approach, including ceramic type selection, process formulation, circuit printing, and functionality testing.
• Innovations:
  • Developed a new technique that integrates traditional ceramic craftsmanship with modern interactive computing technologies.
  • The resulting circuits can flexibly adapt to complex three-dimensional ceramic surfaces, allowing designers to exercise high control over circuit functionality and appearance.
• Implementation Steps and Key Techniques:
  • Use resist-blasting to carve paths on ceramics.
  • Apply conductive ink manually or mechanically, followed by removal of excess coating to leave clear conductive traces on the ceramic surface.
  • Test various conductive materials (silver, nickel, carbon-based) for coating and resistance characteristics.
  • Validate interactive functionality by connecting the developed prototypes to microcontrollers.

Research Outcomes

• Specific Results:
  • Proposed a highly reproducible and adaptable method for manufacturing electronic circuits using resist-blasting and ink coating.
  • Created various interactive ceramic devices, such as touch-sensitive sliders, temperature and humidity sensors, and heating modules.
  • Developed a series of application cases, including temperature-sensitive ceramic tiles for home environments, humidity-sensing floor tiles, and interactive dinner plates.
• Comparative Advantages:
  • Compared to existing technologies, this method is applicable to more complex three-dimensional structures.
  • The resist-blasting technique imparts unique functional aesthetics to the products, enhancing circuit durability and resistance to environmental interference.
• Experimental or Evaluation Results:
  • Circuit performance: Conductive ink adheres stably to ceramic surfaces, with experimental results showing resistance characteristics varying with coating thickness and trace depth.
  • The interactive performance of ceramic interfaces was effectively validated through a series of system prototypes.
• Limitations and Future Directions:
  • Limitations: Adhesion precision is significantly influenced by manual operations, and resistance uniformity is insufficient for wide traces; devices require external microcontrollers for operation.
  • Future Directions:
    1. Explore digital manufacturing processes, such as optimizing laser etching and resist-blasting collaboration.
    2. Expand network control integration for conductive ceramic devices.
    3. Investigate repair techniques for ceramic interactive devices to provide sustainable solutions for extending their lifespan.
