Individuals with profound hearing impairment often face difficulty experiencing the emotional richness of live acoustic environments such as concerts. Although assistive technologies improve communication, they frequently fail to reproduce the subtle, emotional characteristics of sound essential for a deeply immersive experience. Current haptic feedback devices typically convert sound into vibrations using a unidirectional transformation of…

Proprioception is essential for body awareness and motor planning; however, its role in multisensory integration during movement planning remains poorly understood. Most existing tests only assess conscious proprioception through position-matching and localization tasks, overlooking the role of proprioception in movement planning, which occurs at a largely unconscious level. We recently developed a method to reverse…

Information overload is a growing concern in manufacturing environments where operators must make rapid decisions under conditions of uncertainty, ambiguity, and escalating task demands. This study investigated how progressively degraded instructions and increasing informational load affect cognitive performance and physiological stress during a simulated assembly task. Ten participants completed a 49-step digital LEGO assembly set…

Magnetic Resonance Imaging (MRI) of the wrist is difficult because the wrist has a complicated structure and the limitations of the conventional rigid radiofrequency (RF) coils. This research investigates the design and electromagnetic performance of a 4-channel flexible RF coil array intended to improve high-field (7T) wrist MRI imaging. The primary aim is to evaluate…

Of millions of individuals in the U.S. with diabetes, a large percentage will suffer from diabetic foot ulcers—chronic, non-healing wounds that can lead to amputation and death. Available remedies for diabetic foot ulcers include topical therapies or scaffold-based wound dressings. Despite availability, current solutions do not provide sufficient antioxidant release to counteract oxidative stress that…

Plantar pressure analysis tools are commonly used to characterize a variety of gait related pathologies and to track healing progress. Commercial plantar pressure software tools are often expensive and non-modifiable. This project presents Miraculous, an open-source Python tool which allows researchers and clinicians to view, modify, and add to stock data processing pipelines and metric…

Understanding how alternating current (AC) signals propagate through soft tissue is essential for optimizing implantable neurostimulation systems. This study quantifies frequency- and depth-dependent attenuation of AC signals transmitted through ex vivo porcine skin using inductive volume coupling and an implanted Schottky diode circuit. Signals at 50 kHz, 500 kHz, and 1 MHz were delivered through…

This paper presents the design, development, and experimentation of a wireless, battery-free neural stimulation system utilizing an intraoral pathway for power delivery to deep brain targets for the treatment of trigeminal neuralgia. Traditional neuromodulation systems require implantable pulse generators and wired leads. This introduces surgical risks and hardware complications. To address these limitations, a resonant…

Over 14 million people are affected by increased intracranial pressure (ICP) due to traumatic brain injury or conditions like hydrocephalus, which causes excess cerebrospinal fluid in the brain. This research aims to develop and test a novel remote impedance measurement system (RIMS) that uses wireless power transfer between an external ultrasound emitter and an implanted…

This study investigates whether uncomfortable footwear increases neural activation in the primary somatosensory cortex by measuring brain hemodynamic activity via fNIRS (Functional Near-Infrared Spectroscopy). Participants first walked on a treadmill for 5 minutes wearing their regular shoes, then repeated the trial after inserting provided uncomfortable shoe padding, while oxygenated hemoglobin levels, a key indicator of…
