LivingLoom: Investigating Human-Plant Symbiosis through Integrating Living Plants into (E-)Textiles

Research Background and Issues

• Identified Problems or Challenges

  • Traditional textile industries view plants as passive resources, utilizing only their fibers to meet human needs while neglecting the intrinsic value of plants as living organisms.
  • Existing human-plant technology interaction designs focus on the sensory-actuator functions of microorganisms or plants, with limited research on directly integrating seeds into textiles as active materials.
  • The current textile lifecycle (e.g., usage, washing, disposal) overlooks the "living characteristics," limiting users' perception of their value.

• Significance

  • Integrating plants into textiles not only reimagines human-plant coexistence but also promotes sustainable design, advancing more "non-human-centered" design concepts.
  • Exploring the interaction potential between plants and humans could inspire new forms of wearable technologies and electronic textiles.

• Research Motivation and Related Work

  • Human-Computer Interaction (HCI) research has partially explored plant sensory and interactive functions but has yet to delve deeply into the design space of directly integrating seeds into textiles.
  • This study aims to pioneer a "care-driven" manufacturing approach and interactive experiences based on the growth properties of plants.

Solution

• Method or Solution

  • Proposes a "care-driven manufacturing" method, integrating plant seeds directly into yarn during textile production, leveraging the growth and variability of materials to support new designs and user interactions.
  • Developed the LivingLoom system, which uses wet spinning technology to produce seed-containing hydrogel yarns, weaving them into textiles to facilitate plant germination and growth.

• Innovations

  • Technical Innovation: For the first time, plant seeds are directly integrated into fibers via wet spinning, creating growable, perceivable textile materials.
  • Design Innovation: Introduces a "care-based interaction model," emphasizing the user's role as both a wearer and a caregiver throughout the textile lifecycle.
  • Ecological Sustainability: Ensures biodegradability and environmental friendliness of the yarn through bio-based materials (e.g., algae-derived hydrogel).

• Implementation Steps and Key Technologies

  1. Wet Spinning of Seed-Integrated Hydrogel Yarns:
     • Uses materials like sodium alginate and glycerol to create hydrogel yarns while integrating seeds.
     • Adjusts the plasticizer ratio in the hydrogel solution to optimize fiber mechanical properties and seed germination rates.
  2. Textile Integration Methods:
     • Surface Attachment: Manually embroidering the yarn onto base textiles.
     • Structural Interweaving: Using weaving or knitting techniques to embed seed yarns into textiles for support.
     • Layered Hybridization: Combining fabric layers and yarns to enable moisture retention and sunlight absorption.
  3. Electronic Integration for Support Functions:
     • Incorporates humidity and temperature sensors to monitor the plant growth environment and promotes human-plant interaction through tactile feedback.

Research Outcomes

• Specific Results

  • Proposed and validated a new design space: fabric design based on microgreens (hydroponic-adapted plant seeds) covering a 10-day growth cycle.
  • Demonstrated care-driven interaction and its potential in wearable textiles through prototype designs.
  • Developed five sample applications, including a tactile headband, self-watering hat, outdoor sandals, and indoor decorative items.

• Advantages Over Existing Solutions

  • Based on the concept of "human-plant symbiosis," it introduces a non-human-centered textile design approach.
  • Emphasizes users' "care behaviors," fostering deeper relationships between humans and non-human entities.
  • Provides a full lifecycle analysis, integrating textile production, care, and eventual biodegradation into a collaborative design process.

• Experimental or Evaluation Results

  • User studies revealed that wearers developed unique emotional connections to seed-integrated textiles, with daily observation and care inspiring behavioral changes such as adjusting life rhythms and actively learning plant care knowledge.
  • Statistical analysis of different yarn formulations and fabric structures on plant growth rates and mechanical performance highlighted design limitations and optimization directions for key technical configurations.

• Limitations and Future Directions

  • The current study focuses on the early stages of the textile lifecycle (10-day growth cycle), lacking deeper lifecycle analysis of plants and textiles.
  • The compatibility of microgreen seeds is limited by textile techniques and size; future research could explore a broader range of plant types.
  • User study duration was relatively short (3 days), necessitating long-term studies to better understand the evolution of human-plant interactions.

Through this research, the LivingLoom system not only demonstrates technical innovation but also introduces a novel paradigm of human-nonhuman symbiotic interaction, inspiring future sustainable and emotionally meaningful textile design practices.
