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…

Home-based rehabilitation post orthopedic lower-extremity interventions is difficult to monitor objectively, as clinic-based gait labs are expensive, inaccessible for frequent use, and impractical for everyday settings. Patients also often have no clear feedback on whether they are performing prescribed exercises correctly, which may slow recovery and increase the risk of re-injury. This study aims to…

Tissue marking, or tattooing, is used during endoscopic procedures to identify lesions for follow-up and surgical resection. However, existing tattoo inks diffuse extensively, reducing the accuracy of later localization. Tissue-Adhesive Tattoo, Generation 2 (TAT2) is a novel mucoadhesive ink that improves spot containment by more than 90% compared with current clinical inks. Although TAT2 enables…

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…

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…

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…

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…

Validation of core needle biopsy (CNB) devices currently relies on the use of fresh porcine tissue (shoulder, kidney, and connective tissue) which presents significant drawbacks for laboratory testing. Biological tissues inherently vary in mechanical properties and decay rapidly over time leading to inconsistent results, leaving room for improved test evaluation models. To address these challenges,…

The increasing prevalence of skin tears among elderly populations presents a significant clinical challenge, particularly in long-term care settings where fragile skin and reduced mobility elevate injury risk. These wounds not only compromise patient comfort and quality of life but also increase the likelihood of infection, prolong healing time, and raise healthcare costs. Current interventions…

Our concept works to prevent image disturbances in pathology scans by automating the Coverslipping process. The design will reproduce the slide preparation process using robotic automation, applying the appropriate PBS solution and a coverslip. CND Life Sciences aids in the diagnosis of Parkinson’s through skin biopsy to successfully provide a diagnosis before clinical onset. Current…
