Abstract

Muscle fatigue is a highly prevalent condition experienced by individuals of all populations, to different varying degrees. The severity with which muscle fatigue can impact or disrupt an individual’s daily life depends on a number of factors, such as regular level of physical activity leading to the onset of fatigue, or if the fatigue came about as a side effect from another underlying disease or ailment. While most individuals are content with allowing fatigue to subsist via rest and relaxation, others seek a more proactive method in immediate treatment of fatigue. To explore the possibility of developing a system for monitoring and treatment of fatigue, we seek to demonstrate the use of stretchable electronics in non-invasive fatigue monitoring with limited user interaction.

Chapter 1 is an introduction to muscle fatigue and its contributing physiological factors. I discuss potential mechanisms behind and assessment of fatigue, and I also introduce the potential of muscle fatigue analysis with a stretchable platform. Chapter 2 provides background to stretchable electronics and electromyography sensing. Chapter 3 discusses signal processing algorithms for fatigue assessment. Chapter 4 discusses treatment mechanisms for fatigue, including electrical stimulation. Chapter 5 discusses the results of exercise experiments for monitoring fatigue and recovery in the biceps. In the future, this work will provide the foundation for a system capable of obtaining bio-signals from the muscles, processing these signals for fatigue assessment, and treating the afflicted muscle through stimulation therapy.
