Sensors for Diabetic Foot Diagnostics and Ulcer Prevention

 

The goal is to develop 400 sensors to place in a diabetes patient’s shoe to monitor the pressure on their foot and ultimately prevent foot ulcers from developing. The technology is unique because it is designed to measure the pressure and shear on the foot at the same time. The researchers have completed the design of the sensors and have fabricated IC components.

 Explanation of research accomplished.

  • validated the performance of slotted patch antennas and loop antennas for shear and pressure measurements;
  • Realized a smart shoe with shear and pressure sensors embedded in the insole of the shoe;
  • Demonstrated rapid and wireless interrogation of the embedded sensors during walking;
  • Published one journal paper, two conference papers, and one conference presentation;
  • Received funding from UT Transform program to develop a prototype Smart shoe;
  • Filed a provisional patent;
  • Submitted proposals to National Science Foundation and National Institute of Health;
  • Extended the sensor concepts for smart bed and smart prosthetics applications.

 

Sneaker Diabetic Smart Shoe

Current status of projects.

We are working on implementing the interrogation circuits on a printed circuit board so it can be embedded in the insole of the shoes as well. In addition, data processing algorithm that can extract the shear and pressure information from the sensor measurements is under development. We are seeking funding from the National Institute of Health, the National Science Foundation, and DOD Department of Defense Congressionally Directed Medical Research Programs.

 

Publications, Patents filed, additional funding secured for each project

One journal paper has been published. A provisional patent is filed. A small grant from UT Transform program is secured for further refinement of the SmartShoe design and fabrication.
