Conductive yarns can be incorporated into fabrics with traditional textile techniques, such as weaving, knitting and sewing. The electromechanical properties of conductive yarns are very different from conventional yarns, and they also affect the processability during end-product manufacturing processes. However, systematic evaluation of the electromechanical properties of commercial conductive yarns is still elusive. Different conductive materials and production methods for making conductive yarns lead to diverse electromechanical properties. In this work, three types of conductive yarn with different conductive materials and yarn structures were selected for electromechanical characterization. A total of 15 different yarns were analyzed. In addition, the change of resistance with strain was tested to simulate and predict the possible changes in electrical properties of the yarn during weaving, knitting, sewing and other end uses. It was found that Metal-based yarns have good electrical properties but poor mechanical properties. The mechanical properties of Metal-coated yarns are similar to conventional yarns, but their electrical properties are relatively poor. The data shown in this research is instructive for the subsequent processing (weaving, knitting, sewing, etc.) of yarns.}, journal={Textiles}, author={Chen, Yu and Hart, Jacob and Suh, Minyoung and Mathur, Kavita and Yin, Rong}, year={2023}, month={Aug} } @article{suh_park_2022, title={Breast Geometry Characterization of Young American Females Using 3D Image Analysis}, volume={12}, ISSN={["2076-3417"]}, DOI={10.3390/app12178578}, abstractNote={The current research deals with the characterization of breast geometries in young American populations. Breast measurements using 3D image analysis tools are focused on spatial assessments, such as quadrant evaluations of angle, surface area, and volume, together with traditional linear measurements. Through the statistical analysis, different types of breast shapes and placements are clustered, and characteristic breast anthropometry was identified for each cluster. The research findings indicate that there are four shape clusters and three placement clusters. Among the American females aged 26 to 35, four different breast shapes are identified: droopy breasts (31%), small/flat breasts (19%), upward breasts (24%), and large/inward breasts (26%). Taking 36%, 44%, and 20% of the population, respectively, their breast placement characteristics are either high, medium, or low/open. Breast shapes and placement are highly associated with each other. Larger breasts are located relatively lower, while most smaller/flat breasts are positioned relatively high.}, number={17}, journal={APPLIED SCIENCES-BASEL}, author={Suh, Minyoung and Park, Jung Hyun}, year={2022}, month={Sep} } @article{mukai_suh_2022, title={Design and characterization of a cotton fabric antenna for on-body thermotherapy}, volume={6}, ISSN={["1530-8057"]}, DOI={10.1177/15280837221107160}, abstractNote={ As a non-invasive therapeutic modality, microwave hyperthermia has gained increasing prominence in recent breast cancer research. In microwave hyperthermia, the temperature of a cancerous lesion is raised to 39–45°C by microwave irradiation to shrink tumors. Currently available applicators in clinics are aperture antennas (or waveguides) that are bulky and stationary; as such, patients are required to stay in an uncomfortable position for an extended period of time. On this account, this paper introduces the design and characterization of a novel cotton fabric antenna for a truly wearable and patient-friendly breast hyperthermia therapy. The developed antenna, consisting of cotton and copper-plated polyester fabrics, offers flexibility, tenacity, moisture-absorbing properties and breathability desirable for potential integration into intimate apparel. On the other hand, the use of cotton fabric brings about a major concern: moisture is documented to alter the dielectric properties of cotton fabrics and hence could impact the antenna performance. Therefore, for the purpose of concept and design validation, this research investigated the impedance matching and heating performance at three levels (20%, 65% and 80%) of relative humidity (RH). From both simulations and measurements, the RH was found to shift the resonant frequency slightly, but did not critically affect the impedance matching and the heating performance – the measured temperature rises were 4.7–4.9°C and 2.3–2.5°C at the depths of 5 mm and 15 mm, respectively. These theoretical and experimental insights cast light on the feasibility and benefits of moisture-absorbing, cotton-based medical textiles for administration of highly patient-friendly breast hyperthermia. }, journal={JOURNAL OF INDUSTRIAL TEXTILES}, author={Mukai, Yusuke and Suh, Minyoung}, year={2022}, month={Jun} } @article{mukai_li_suh_2021, title={3D-printed thermoplastic polyurethane for wearable breast hyperthermia}, volume={8}, ISSN={["2198-0802"]}, DOI={10.1186/s40691-021-00248-7}, abstractNote={Abstract}, number={1}, journal={FASHION AND TEXTILES}, author={Mukai, Yusuke and Li, Sixian and Suh, Minyoung}, year={2021}, month={May} } @article{mukai_suh_2021, title={Development of a conformal woven fabric antenna for wearable breast hyperthermia}, volume={8}, ISSN={["2198-0802"]}, DOI={10.1186/s40691-020-00231-8}, abstractNote={Abstract}, number={1}, journal={FASHION AND TEXTILES}, author={Mukai, Yusuke and Suh, Minyoung}, year={2021}, month={Feb} } @article{mukai_suh_2021, title={Enhancing the Electrical Properties of Inkjet-Printed Silver Ink by Electrolyte Sintering, Photonic Sintering, and Electroless Plating}, volume={53}, ISSN={["0350-820X"]}, DOI={10.2298/SOS2101119M}, abstractNote={Conductive inkjet printing is an emerging rapid manufacturing technology in the field of smart clothing and wearable electronics.

Post-treatments are commonly employed to enhance the electrical conduction of inkjet-printed tracks. This research discusses the effects of electrolyte sintering, photonic sintering and electroless copper plating on the DC electrical resistance and resistivity of inkjet-printed silver nanoparticles.

Consequently, the predicted displacements have not yet been satisfactorily validated. In this study, real time motion capture of the natural vibrations of a breast that followed, after raising and allowing it to fall freely, revealed an obvious difference in the vibration characteristics above and below the static equilibrium position. This implied that the elastic and viscous damping properties of a breast could vary under extension or compression. Therefore, a new piecewise mass-spring-damper model of a breast was developed with theoretical equations to derive values for its spring constants and damping coefficients from free-falling breast experiments. The effective breast mass was estimated from the breast volume extracted from a 3D body scanned image. The derived spring constant (ka = 73.5 N m−1) above the static equilibrium position was significantly smaller than that below it (kb = 658 N m−1), whereas the respective damping coefficients were similar (ca = 1.83 N s m−1, cb = 2.07 N s m−1). These values were used to predict the nipple displacement during bare-breasted running for validation. The predicted and experimental results had a 2.6% or less root-mean-square-error of the theoretical and experimental amplitudes, so the piecewise mass-spring-damper model and equations were considered to have been successfully validated. This provides a theoretical basis for further research into the dynamic, nonlinear viscoelastic properties of different breasts and the prediction of external forces for the necessary breast support during different sports activities.}, number={1}, journal={Journal of Biomechanics}, publisher={Elsevier BV}, author={Cai, Yiqing and Chen, Lihua and Yu, Winnie and Zhou, Jie and Wan, Frances and Suh, Minyoung and Chow, Daniel Hung-kay}, year={2018}, month={Jan}, pages={137–143} } @misc{mukai_suh_2018, title={Development of a Conformal Textile Antenna for Thermotherapy}, author={Mukai, Y. and Suh, M.}, year={2018}, month={Oct} } @article{curto_garcia-miquel_suh_vidal_lopez-villegas_prakash_2017, title={Design and characterization of a phased antenna array for intact breast hyperthermia}, volume={34}, ISSN={["1464-5157"]}, DOI={10.1080/02656736.2017.1337935}, abstractNote={Abstract Purpose: Currently available hyperthermia technology is not well suited to treating cancer malignancies in the intact breast. This study investigates a microwave applicator incorporating multiple patch antennas, with the goal of facilitating controllable power deposition profiles for treating lesions at diverse locations within the intact breast. Materials and methods: A 3D-computational model was implemented to assess power deposition profiles with 915 MHz applicators incorporating a hemispheric groundplane and configurations of 2, 4, 8, 12, 16 and 20 antennas. Hemispheric breast models of 90 mm and 150 mm diameter were considered, where cuboid target volumes of 10 mm edge length (1 cm3) and 30 mm edge length (27 cm3) were positioned at the centre of the breast, and also located 15 mm from the chest wall. The average power absorption (αPA) ratio expressed as the ratio of the PA in the target volume and in the full breast was evaluated. A 4-antenna proof-of-concept array was fabricated and experimentally evaluated. Results: Computational models identified an optimal inter-antenna spacing of 22.5° along the applicator circumference. Applicators with 8 and 12 antennas excited with constant phase presented the highest αPA at centrally located and deep-seated targets, respectively. Experimental measurements with a 4-antenna proof-of-concept array illustrated the potential for electrically steering power deposition profiles by adjusting the relative phase of the signal at antenna inputs.

A light wearable system can improve patient comfort and be located in close proximity to the breast, thereby enhancing energy deposition and reducing power requirements. The objective of this work was to design and assess the feasibility of a conformal patch antenna element of an array system to be integrated into a wearable hyperthermia bra. The feasibility of implementing antennas with silver printed ink technology on flexible substrates was evaluated. A coupled electromagnetic-bioheat transfer solver and a hemispheric heterogeneous numerical breast phantom were used to design and optimize a 915 MHz patch antenna. The optimization goals were device miniaturization, operating bandwidth, enhanced energy deposition pattern in targets, and reduced Efield back radiation. The antenna performance was evaluated for devices incorporating a hemispheric conformal groundplane and a rectangular groundplane configuration. Simulated results indicated a stable -10 dB return loss bandwidth of 88 MHz for both the conformal and rectangular groundplane configurations. Considering applied power levels restricted to 15 W, treatment volumes (T>410C) and depth from the skin surface were 11.32 cm3 and 27.94 mm, respectively, for the conformal groundplane configuration, and 2.79 cm3 and 19.72 mm, respectively, for the rectangular groundplane configuration. E-field back-radiation reduced by 85.06% for the conformal groundplane compared to the rectangular groundplane configuration. A prototype antenna with rectangular groundplane was fabricatd and experimentally evaluated. The groundplane was created by printing silver ink (Metalon JS-B25P) on polyethylene terephthalate (PET) film surface. Experiments revealed stable antenna performance for power levels up to 15.3 W.

Anomalous behavior of static charge when measured at a temperature of 35°C, provided a meaningful clue to control the environmental conditions in the textile industry.}, number={3}, journal={Journal of Textile Institute}, publisher={Informa UK Limited}, author={Suh, M. and Seyam, A.M. and Oxenham, W. and Theyson, T.}, year={2010}, pages={261–269} } @misc{kim_smith-jackson_carroll_suh_mi_2009, title={Implications of Participatory Design for Wearable Near and Far Environment Awareness System for Users with Severe Visual Impairments}, ISBN={9783642027062 9783642027079}, ISSN={0302-9743 1611-3349}, url={http://dx.doi.org/10.1007/978-3-642-02707-9_10}, DOI={10.1007/978-3-642-02707-9_10}, abstractNote={This paper presents experiences from a study that included five users with Severe Visual Impairments (SVIs), fashion designers, and human factors engineers. We used participatory design (PD) to develop a wayfinding and object-recognition system. The PD study consisted of three sessions and was designed to include actual users in the design process. The primary goal of the PD was to validate the system concept and to determine the attributes of system interaction. Two of the three sessions are discussed here. We obtained several insights from a technological perspective, textile and apparel perspective, and user interface design perspective. Among the results identified, users with SVIs preferred to wear assistive technology unless that was not distracting to the participant or those that came into contact with the participant. Auditory feedback was chosen as a primary modality in user interface design, and we realized that constructing a good pool of PD members is essential to transform actual users’ needs and requirements into the design process.}, journal={Universal Access in Human-Computer Interaction.
