The population in Ohio and everywhere continues to grow older and many challenges remain which require low cost, efficient solutions which are deeply rooted in engineering design and use available technology. This project is to address the challenges associated with predicting risk of falls in older adults. Thus reducing health care cost and improving quality of life for older adults. Using clinical studies as well as simulation tools, this research seeks to identify markers for predicting falls during activities of daily living.

Recent mathematical models of human posture have been explored to better understand the space of control parameters that result in stable upright balance. These models have demonstrated that there are two types of instabilities – a leaning instability and an instability leading to excessive oscillation. While these models provide insight into the stability of upright bipedal stance, they are not sufficient for individuals that require the aid of assistive technologies, such as a passive-cane or a walker. Without a valid model one is unable to understand the control parameters required for maintain upright posture or if similar instabilities even exist when assistive technologies are used. Therefore, in this study, we developed a mathematical model of human posture while using a passive-cane to examine the nonlinear dynamics of stance. This study will enable design of a better cane for use in balance and gait.

Design of a Controller for Surgical Cutting Tools

Team:

Amit Shukla (Mechanical & Manufacturing Engineering)

Nonlinear dynamics is exhibited by electro-mechanical-structural systems under certain operating conditions. This nonlinear phenomenon, for harmonically excited systems, may include emergence of sub- harmonic and/or super harmonic response. Linear analysis tools inherently fail to capture the nonlinear phenomena in the design stage and hence are of little value when utilized for prediction of nonlinear dynamics of interest and the associated parametric analysis for trade-off studies. Many sources of nonlinearities are inherent in the ultrasonic cutting tool which include geometric, material, piezoelectric nonlinearities. This research is to investigate a design of controller for operating these cutting tools.

Energy harvesting for cardiac pacemakers would enable technology to eliminate repeated battery removal and replacement in patients. This project seeks to identify and exploit nonlinear sub harmonic resonance associated with nonlinear oscillators to design and develop energy harvesters with tunable frequency response characteristics. The students from Miami University and Technical University of Eindhoven are collaboratively working on this project.
