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.

Disposable, Medication-integrated Tactile and Motion Sensor for Glaucoma Therapy Compliance Improvement

Sponsor:

Start Date: 7/01/20

End Date: 8/31/21

Abstract

Glaucoma is the leading cause of irreversible blindness in the world. The number of people with primary open angle glaucoma (POAG) is expected to exceed 100 million by 2040. The first-line therapy for glaucoma treatment is patient-administered hypotensive medication delivered topically via an eye drop to reduce intraocular pressure. However, patient compliance with glaucoma drop therapy is a persistent and well-known problem without a viable solution. Studies have consistently shown the extent of the problem: nearly 50% of individuals discontinue topical ocular hypotensive therapy entirely within six months of their first prescription; of those that persist beyond six months, only 37% continue the therapy after three years; and only 10% of those prescribed glaucoma drops are persistent (without gaps) over the first year. This widespread failure to adhere dramatically reduces the effectiveness of eye drops in reducing intraocular pressure and delaying the progression of glaucoma. The prevalence of glaucoma and the magnitude of the adherence issue has led to the development of numerous alternative treatment therapies, including implantable slow-release drugs and minimally-invasive glaucoma surgery (MIGS). Likewise, technological solutions of varying complexity for tracking glaucoma drop adherence have been proposed by several groups. Retinal Care’s proposed solution is fundamentally different. The tool proposed here is a relatively straightforward, inexpensive combination of sensors designed to provide crucial feedback to patients, providers, and payers on the way a patient interacts with an eye drop applicator. This interaction, which includes both tactile and motion data via a force-sensitive resistor (FSR) and an accelerometer, can be leveraged to actively monitor drop adherence and drop administration mechanics. More importantly, that data can be used to provide decision support on how and when to intervene with the patient, how and when to incentivize, how and when to educate (on correct drop administration, for example), and, crucially, when to forego drop therapy entirely and transition to something less dependent on patient compliance such as minimally-invasive glaucoma surgery (MIGS) or an implanted slow-release drug formulation. Retinal Care approaches eye care, and health care in general, more holistically than traditional companies; recognizing the behavioral and psychosocial factors that are a root cause of blindness from manageable diseases like glaucoma, diabetic retinopathy, and age-related macular degeneration. While Retinal Care employs cutting-edge technology such as deep learning, novel electroretinography tools, and the device proposed here, we understand and work actively toward implementing technology in a way that translates directly to improved quality of life for our patients by managing the entire care path. The ability to track glaucoma adherence alone, for example, does nothing to reduce blindness. The technology proposed here, while novel in design, is not intended primarily as an eye drop tracking tool, though we expect it will accomplish that sub-goal with greater effectiveness and at less cost than any product on the market or in development. Instead, it is designed explicitly to reduce blindness by providing Retinal Care the crucial data needed to tailor our interaction and intervention strategies to the individual patient; to maximize patient engagement in their glaucoma care through a combination of incentivization, education, tailored communications, and interaction with trained care coordinators.

Canine Bite Force Sleeve: Proposal for TE/TT Capstone Design Program

Sponsor:

Start Date: 9/01/18

End Date: 12/31/20

Abstract

Working dogs play an integral role in the day to day operations of both military soldiers and law enforcement officers worldwide. All canine handlers and trainers use protective bite sleeves for engagement and apprehension training. However, the canine bite sleeves on the market today fail to measure the bite force of the working dog. The result is that trainers must rely on years of training experience to subjectively evaluate their canines which may result in ineffective training, canine/handler injury or unsafe environments during operations. The development of the canine bite force sleeve would help provide an objective measurement tool for trainers to more thoroughly understand canine bite dynamics. The objective of the project is to re-design a commercial bite sleeve by incorporating electronic (or other) pressure sensors within the sleeve that accurately measures, records, and displays bite force data in real time. Canine bite profile includes overall bite pressure, mapping the bite print and duration of a bite.

Textiles Senior Design Projects

Sponsor:

Start Date: 3/05/19

End Date: 4/30/19

Abstract

This project involves 2 senior design projects. The goal of the first project (Wall Tent Fabric Development) is to develop a fabric that meets criteria to make economical wall tent panels with specific performance criteria. The fabric needs to be waterproof, mildew resistant, fire retardant and meet a minimum specification for tear strength. The project team will work with a range to fabric producers to characterize materials that meet the minimum specifications, creating sample for sew testing, and determining the most cost effective fabrics for the required performance criteria. Project to begin Spring Semester 2019. The goal of the second project (Modular Wall Tent) is to identify new strategies for the implementation (sew/construct) of panels of various sizes and purposes (i.e wall tents, roofs, plain walls, windowed walls, doors, vestibules, etc.) into a customized tent system. Design and validate a modular system where individuals could but various sewn panels but "connect" them to build their own tent design in their backyard or campground. The connection mechanism is the key to this project, with factors based on the ease and durability of the connection. Project to begin Spring Semester 2019.
