  • highly sensitive textile based strain sensors using poly 3 4 ethylenedioxythiophene polystyrene sulfonate silver nanowire coated Nylon Threads with poly l lysine surface modification
    RSC Advances, 2017
    Co-Authors: Jimi Eom, Jae Sang Heo, Minho Kim, Jun Ho Lee, Sung Kyu Park, Yonghoon Kim
    Abstract:

    Here, we demonstrate highly sensitive textile-based strain sensors using poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS)/silver nanowire (Ag NW)-coated Nylon Threads for electronic textile applications. For the coating of Ag NW and PEDOT:PSS layers, we employed a simple and cost-efficient ‘dip and dry’ method which facilitated conformal coating of Ag NWs and PEDOT:PSS on cylindrical-shaped Nylon filaments. In this study, to improve the stability of the strain sensor, we employed poly-L-lysine (PLL) surface modification of Nylon Threads prior to the Ag NW coating process. By stability tests, it was found that the PLL surface modification significantly improved the operational stability of the strain sensor, attributed to the enhanced adhesion between Ag NWs and Nylon Thread. By mechanically sewing the PEDOT:PSS/Ag NW/Nylon Thread onto a fabric, a textile-based strain sensor was fabricated, exhibiting strain gauge factors of 1.69–3.31 (strain range of 5–20%) and stable operation up to ca. 1000 stretch–release cycles. Furthermore, as a possible extensive use of the PEDOT:PSS/Ag NW/Nylon Threads, a capacitive-type touch/pressure sensor was also demonstrated on a textile platform.

  • Piezoresistive Characteristics of Nylon Thread Resistive Memories for Wearable Strain Sensors
    Coatings, 2019
    Co-Authors: Ting-kuo Kang
    Abstract:

    A Nylon Thread (NT) resistive memory is fabricated by performing a simple dip-and-dry solution process using graphene–poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate) (PEDOT:PSS) conductive ink. The piezoresistive characteristics of the NT resistive memory are further evaluated for wearable strain sensors. While a stretching strain (e) is applied to the NT resistive memory, the relative resistance change of low-resistance state (LRS) is found to be higher than that of high-resistance state (HRS). This result implies that the contribution of the local overlapping interconnection change in graphene and PEDOT:PSS materials to the LRS resistance change is greater than that to the HRS resistance change. In addition, through many cycles of repeatedly stretching and releasing the LRS of the NT resistive memory at a fixed e = 7.1%, a gauge factor of approximately 22 is measured and achieved for a highly sensitive and durable strain sensor. Finally, the actual integration of the NT resistive memory into textiles can provide resistive memory and piezoresistive sensor applications simultaneously for wearable electronic textiles.

  • Highly Stretchable Non-volatile Nylon Thread Memory
    Scientific Reports, 2016
    Co-Authors: Ting-kuo Kang
    Abstract:

    Integration of electronic elements into textiles, to afford e-textiles, can provide an ideal platform for the development of lightweight, thin, flexible and stretchable e-textiles. This approach will enable us to meet the demands of the rapidly growing market of wearable-electronics on arbitrary non-conventional substrates. However the actual integration of the e-textiles that undergo mechanical deformations during both assembly and daily wear or satisfy the requirements of the low-end applications, remains a challenge. Resistive memory elements can also be fabricated onto a Nylon Thread (NT) for e-textile applications. In this study, a simple dip-and-dry process using graphene-PEDOT:PSS (poly(3,4-ethylenedioxythiophene) polystyrene sulfonate) ink is proposed for the fabrication of a highly stretchable non-volatile NT memory. The NT memory appears to have typical write-once-read-many-times characteristics. The results show that an ON/OFF ratio of approximately 10^3 is maintained for a retention time of 10^6 s. Furthermore, a highly stretchable strain and a long-term digital-storage capability of the ON-OFF-ON states are demonstrated in the NT memory. The actual integration of the knitted NT memories into textiles will enable new design possibilities for low-cost and large-area e-textile memory applications.

Resistive memory elements can also be fabricated onto a Nylon Thread (NT) for e-textile applications. In this study, a simple dip-and-dry process using graphene- PEDOT PSS (poly(3,4-ethylenedioxythiophene) polystyrene sulfonate) ink is proposed for the fabrication of a highly stretchable non-volatile NT memory. The NT memory appears to have typical write-once-read-many-times characteristics. The results show that an ON/OFF ratio of approximately 10(3) is maintained for a retention time of 10(6)s. Furthermore, a highly stretchable strain and a long-term digital-storage capability of the ON-OFF-ON states are demonstrated in the NT memory. The actual integration of the knitted NT memories into textiles will enable new design possibilities for low-cost and large-area e-textile memory applications.
