Electronic textiles (e-textiles) merge textiles and electronics to monitor physiological and environmental changes. Innovations in textile functionalities and diverse applications have propelled e-textiles’ popularity. However, challenges like connection with external devices for signal processing and reliable interconnections between flexible textiles and rigid electronic circuits persist. Wearable connectors enable the effective communication of e-textiles with external devices. Factors such as electrical functionality and mechanical durability along with textile compatibility are crucial for their performance. Merging the rigid connectors on the flexible textiles requires conductive and flexible interconnects that can bridge this gap between soft and hard components. This work focuses on designing two-part detachable mechanical snap connectors for e-textiles. The textile side connectors are attached to the data transmission cables within the textiles using three interconnection techniques—conductive epoxy, conductive stitches, and soldering. Three types of connectors were developed that require three detaching or unmating forces (low, medium, and high). All connectors were subjected to 5000 mating–unmating cycles to evaluate their mechanical durability and electrical performance. Connectors with low and medium unmating forces exhibited a stable performance, while those with high unmating forces failed due to wear and tear. Conductive stitches maintained better conductance as compared to conductive epoxy and soldering methods.

The advent of wearable electronic textiles (e-textiles) is transforming human–computer interaction by enabling seamless, comfortable, and continuous connectivity between users and digital systems. Although the wearable e-textile market is poised for significant growth, there is a need for durable, reliable connectors to link e-textiles to digital systems. This study presents and evaluates two novel magnetic connectors—buckle and snap—integrated into textile substrates using conductive epoxy, conductive stitches, and solder as interconnect methods. Durability testing involved 5000 mating/unmating cycles at low, medium, and high forces, with electrical performance assessed through resistance and impedance measurements. Results showed significant increases in resistance and impedance with 1000-cycle intervals. However, both connectors retained robust electrical and mechanical integrity, with all resistance values remaining below 1.6 Ω, indicating no critical degradation. Buckle connectors consistently outperformed snap connectors, which is attributed to their design that reduces mechanical stress on interconnects. Conductive epoxy demonstrated superior stability and slower degradation compared to conductive stitches and solder, particularly under higher mating forces. Impedance results mirrored resistance trends, confirming reliability. These findings advance durable, user-friendly connectors for long-term e-textile use, addressing both mechanical endurance and electrical performance to enhance wearable computing and interactive environments.

The escalating volume of textile waste poses a critical challenge to global sustainability efforts. Each discarded garment, whether heavily worn, lightly worn, or unused, contributes to a growing environmental crisis. While sustainability remains the overarching goal, circularity offers a practical and immediate pathway to mitigate textile waste through reuse, repair, and recycling. However, a significant barrier to circularity is the industry’s inability to preserve and access a garment’s unique “fingerprint,” vital information such as fiber composition. Without this, efficient bulk sorting, and the production of high-purity feedstock for recycling remain limited. This paper presents a comprehensive overview of the current textile waste management infrastructure, identifying key operational challenges, particularly those related to sorting and feedstock purity. It emphasizes the growing need for scalable solutions that can automate and enhance material identification at the end of a garment’s life. Radio frequency identification (RAIN) emerges as a promising technology to address this gap. By embedding RAIN tags directly into garments, it becomes possible to track items throughout their lifecycle. The paper also examines market forces accelerating RAIN adoption, including evolving regulatory mandates for product-level traceability, increasing brand participation driven by competitive pressure, and advancements in embedded and mobile device-readable RAIN tags. Alongside a comparative analysis of alternative identification technologies, the article concludes with a forward-looking vision of how a RAIN-enabled framework could empower producers, brands, consumers, and sorters, unlocking the full potential of textile circularity.
