QL+ UTSA projects are centered around developing designs, the innovation, and implementation of the latest device technologies in order to advance the quality of life for many individuals.

Knife Polisher

(In Progress)

Team is collaborating with reforged to design a knife sharpening device. Many veterans suffer from musculoskeletal injuries and constant back and forth motions can pose serious pain during the sharpening process. The team is in the design process to facilitate sharpening of the blade.

Tools for Tremors


Group designed a device that will allow a veteran with Essential Tremor ("ET), specifically intention tremor, to use a hammer.  We designed the TremAid Hammer for veterans that suffer from ET.  This device is for veterans that would like to pursue their hobbies or continue working, but their tremors hinder them from using a traditional hammer. Our goal was to create a safe alternative to the traditional hammer.

Having an amputated limb means you not only have to deal with the prosthetic itself, but the additional problems that it brings with it. One of these common issues is excess heat build up inside of the prosthetic. With fewer muscles to carry the load, more energy is produced by the body at these injured sites and results in excess heat production. The prosthetic device drastically slows the body’s natural cooling processes by limiting the wound’s access to efficient heat transfer. This device should replace the liner and stump sock currently used today to limit the effects that the excess heat can cause.

The idea of the project is to recreate an EMG with a smaller microcontroller and paint wires to minimize size, and maximize comfort alongside usability. With the sleeve design, developers would have an easier time incorporating biometric readings and data output. The application goals of this team is to overcome traditional wired circuit board of EMG device provide comfort for potential all day wear, and make the EMG device simple and modular.

The device is trying to solve restriction of movement in the hand of the user. It is also creating a new sense of motion if the user could not move their hand independently due to some physical injury. The goal of the hand-brace is to allow the user to clamp their hand around objects to lift, use, as well as release items of need or want. It will utilize an EMG coupled with computer programming to allow the user to open and close their hand. The idea is to have the device be attached to the hand and wrist with the EMG sensor on the forearm and elbow. Overall, the device should improve upon the user’s quality of life and independence.

The team is working on designing and fabricating an electromyogram. Implementing basic electrical components, we would to design a working EMG for measuring the activity of certain skeletal muscles. This design process would include assembling of the device and calibration of the equipment to adequately read the bio electrical signals. The purpose for this EMG would be its implementation in other, more complex, mechanisms. One of the highest applications in mind for this device would be its unification with mechanical prosthesis to provide a functional artificial limb that moves in unison with certain biochemical signals of the upper limb.

AI Optimization of Myoelectric Controlled Prostheses with Feedback Systems (Completed)

This teams project aims to tackle the dispersion of different systems in current electronic prostheses and combine them into a single high functioning system. They plan to incorporate AI systems to improve feedback, input and output signals. The overall goal is to improve function and decrease the user’s learning curve that exists in current prostheses. Problems include combining multiple systems into a single system and overcoming possible varying signals regarding both input and output.
