texTENG: Fabricating Wearable Textile-Based Triboelectric Nanogenerators
🤖 AI Summary
Textile-based triboelectric nanogenerators (TENGs) face limited adoption in wearable computing due to material scarcity, complex fabrication processes, and inherent structural rigidity. Method: This paper introduces texTENG—a modular, open-source framework for rapid prototyping of textile TENGs tailored for makers and the human-computer interaction (HCI) community. It features a novel multi-dimensional structural design menu supporting weaving, knitting, and braiding, compatible with manual and semi-automated techniques (e.g., crocheting, plain-weave weaving, single-needle knitting) using only off-the-shelf conductive and dielectric textiles—no cleanroom or specialized equipment required. Contribution/Results: Fabricated devices exhibit high flexibility, breathability, and motion conformity, delivering output voltages of several hundred volts and microampere-level currents—sufficient to power LEDs, capacitive touch sensors, and low-power Bluetooth modules. texTENG substantially lowers the barrier to TENG prototyping, enabling sustainable smart garments and interactive wearable systems.

📝 Abstract
Recently, there has been a surge of interest in sustainable energy sources, particularly for wearable computing. Triboelectric nanogenerators (TENGs) have shown promise in converting human motion into electric power. Textile-based TENGs, valued for their flexibility and breathability, offer an ideal form factor for wearables. However, uptake in maker communities has been slow due to commercially unavailable materials, complex fabrication processes, and structures incompatible with human motion. This paper introduces texTENG, a textile-based framework simplifying the fabrication of power harvesting and self-powered sensing applications. By leveraging accessible materials and familiar tools, texTENG bridges the gap between advanced TENG research and wearable applications. We explore a design menu for creating multidimensional TENG structures using braiding, weaving, and knitting. Technical evaluations and example applications highlight the performance and feasibility of these designs, offering DIY-friendly pathways for fabricating textile-based TENGs and promoting sustainable prototyping practices within the HCI and maker communities.
