Research

Dr. Jur leads the Nano-EXtended Textiles (NEXT) research team, which aims to leverage nanotechnology materials and processing methods in to impart new characteristics to polymer films and fibers, with a specific focus on electronic and electro-optical modifications. Such an investigation requires a engineering design philosophy to be applied toward the ‘system-level’ development of the textiles and electronics to advance our technologies beyond the lab. Of particular interest to the NEXT team is the design of ‘smart’ textile platforms (wearable,internet of things) that enable improved materials integration of sensors, energy harvesting, energy storage, and communication devices.

Abstract

The overarching goal of this research project is to explore the fundamental principles of electronics integration in wearable platforms, while at the same time transitioning these strategies toward the development of the ASSIST defined testbeds. A key differentiator of the ASSIST NERC to commercially developed platforms (wristbands, chest straps) is the ability to make novel integrated wearable systems on textile platforms. E-Textiles is considered a truly disruptive technology that will begin to establish itself in major applications in the near future. Through our efforts with ASSIST, the PI’s research team in textile engineering has been leading the effort in design of electronics/sensors integration in textiles and the development of novel electronics platforms that enables the evaluation of on-body energy harvesting. These textile-based platforms will serve as a basis for an open-source/open-integration system to promote academic and industrial advances in wearable energy harvesting (Thrust 1), sensors (Thrust 3), communications (Thrust 4), and low power electronics (Thrust 4). This research not only supports the current testbed generations, but serves as launch points for the development of future testbed generations and possible new testbeds definitions. In this current year projects, we aim to focus on 3 separate research projects, 1 undergraduate engineering project, and 1 course development project – 1) Durable e-Textiles Sensors for the Human Microclimate: Based on our prior effort for durable, electrically conductive traces on textiles, methods for ink printing and atomic layer deposition patterning will be incorporated studied for biochemical and thermal sensing directly in the textile. 2) Materials evaluation for the body ‘energy map’: The Energy Harvesting Subsystem, developed in Yr 3, will be used for to evaluate textile-inspired heat spreader and heat sink designs using nanoscale materials techniques in ink printing and atomic layer deposition. Human trial studies will be performed for evaluation of ASSIST devices and the materials developed. 3) Isotropic ALD-modified CNT mesoscale structures for thermal and moisture management: Thermal management opportunities exist in the through the use of mesoscale structures of nanoscale materials, such as aligned CNTs foams. This effort, in conjunction with Philip Bradford in Textile Engineering, Chemistry and Science at NCSU, will study the isotropic thermal and capillary wicking ability of aligned CNT foams with ALD modified surfaces that enables control of thermal conductivity, thermal insulation properties, and liquid surface tension. 4) TECS/ECE Senior Design Project: IoT integration on the garment is a missing link toward allowing user-informed decisions on the state of their garment and their health. In this effort, a Senior Design team in the PI’s Engineering Design course will lead an effort to use embedded sensor technology to provide an estimated use lifetime of a garment. This effort will be in conjunction with Tom Snyder and an IAB member company 5) E-textiles Multi-disciplinary Course Development: Materials, Concepts and Design: In Spring 2014, the PI developed a new course which provides students the ability to utilize the engineering design process to create new concepts in engineering design. In the coming year, the PI aims to develop this course so as to become a multi-disciplinary opportunity for ASSIST students at NC State and at partner institutions. In addition to aforementioned research projects, our team will lead the development of the ‘Health and Environment Tracker Testbed’ and support on-body integration of the ‘Self-Powered and Adaptive Low Power Platform Testbed’.

Conductive Ink-Jet Printing of Conductive Patterns on Textiles

Sponsor: FUJIFILM Corporation

Start Date: 10/16/17

End Date: 12/31/18

Abstract

The goal of this research proposal is to develop design principles for ink-jet printing on textile substrates as a function of the textile construction and surface pretreatments. Conductive ink-jet printing is a rapidly developing in the flexible electronics world, which has been benefiting by the rapid market growth of the wearables industry. Opportunities exist for the use of conductive inks in textile-based wearable (and non-wearable) applications which requires custom-based high-throughput, roll-to-roll capabilities that are a trademark for inkjet printing. The primary challenge is understanding how to print on the textured surface of the fabric so as to obtain a continuous conductive pattern, all awhile ensuring that the conductive pattern withstands the durability requirements of the textile upon which it is applied. This research aims to perform a design of experiments that develops correlation factors between patterning effects of conductive ink printing based on the textile fiber, yarn and construction. Furthermore avenues for pretreatments of the textile to improve the adhesion of the conductive ink print will be explored and tested against standard textile durability tests.
