A Voice Activated Prosthetic Mode Of Control, Will Picken

UNO Student Research and Creative Activity Fair

There are many options for a prosthetic mode of control. The most commonly created modes of control involve surface EMG (sEMG) and require that the user have well defined muscle activation in order to trigger the movement of the prosthetic. Unfortunately, many prosthetic users do not have the required muscle tone or strength to trigger these sensors, so the need for a control mechanism that doesn’t rely on sEMG is clear. This study focuses on the development of a low-cost, voice activated prosthetic mode of control compatible with the prosthetics developed by Dr. Zuniga and his research team.

An Electrooculography Prosthetic Control System, Walker Arce

UNO Student Research and Creative Activity Fair

For many surface EMG (sEMG) prosthetic control systems, the muscles on the affected limb are used to trigger the control system. This can lead to fatigue in the user as they have to maintain continuous muscle activation and coactivation in order to achieve prosthetic control [3]. The crux of any prosthetic control system is the human machine interface that is developed, and at present many control systems have complicated interfaces that limit the degrees of freedom of the prosthetics. This study focuses on the development of a low-cost prosthetic control peripheral that is compatible with the prosthetics developed by Dr. …

A Radio Frequency Identification (Rfid) Prosthetic Control System, Andrew Butler

UNO Student Research and Creative Activity Fair

Item classification and tagging in embedded systems has become ubiquitous in our society due to radio frequency identification (RFID) and the cost has dropped significantly for hardware that can interact with these devices. Due to this, possibilities in the realm of prosthetic control systems opens up for dynamic grip selection without user intervention. This study focuses on the development of a device capable of this functionality that is compatible with the prosthetics designed by Dr. Zuniga and his research team.

The printed circuit board (PCB) was designed using the EAGLE EDA package and incorporates a lithium polymer battery with a …

Development And Testing Of 3d Printed Prostheses, Orthoses, And Assistive Devices For Children And Adults, Walker Arce

UNO Student Research and Creative Activity Fair

User controllable interfaces for exoskeletons have consisted of either switch controlled interfaces, for ‘on’ or ‘off’, or elastic powered schemes that allow the user’s wrist flexion to provide the resistance for their therapy. This project aims to develop a hands-free mode of control for the exoskeleton, that uses more advanced electronic components to achieve a more natural user interface. Our approach to this project is the prototyping of a control system that uses the MyoBand Gesture Control Armband (MyoBand), and a simple Arduino based electronic design. The three modes of operation possible for this design is measuring the electrical signals …

Quantifying Static And Dynamic Stability Using Mobile Sensors, Mason Schleu

UNO Student Research and Creative Activity Fair

Balance disorders impact millions of people causing substantial impact on quality of life due to psychological and physical hardships associated with poor balance. However, a clinically relevant, low cost, self-service system in detecting such disorders does not exist. Previous research has shown the built in accelerometer and gyroscope sensors of a smart phone to be valid tools in detecting standing balance performance using traditional linear analysis, however, such a system has yet to be proven useful in detecting dynamic postural variability. Indeed, more quantitative methods than are typically used in clinical settings are necessary for early detection of poor postural …
