Our device is a single-microneedle attachment that administers liquid nitrogen in a top-down manner. By delivering the cryogen 2-3 mm below the surface of the skin, this novel top-down intralesional cryogen administration allows for keloid tissue remodeling below the surface, resulting in a more effective cryotherapy treatment while still reducing additional skin trauma.

Rational design of a LiMn2O4 composite cathode through investigation of the impact of catholyte mechanical properties, cathode active material particle size distribution, and cathode active material content on ionic transport, stress evolution, capacity retention, and mechanical degradation.

Novel soft robotic rehabilitation device designed to assist in the range-of-motion therapy of the shoulder in newborns with brachial plexus palsy. This device emulates physical therapies focused on motor stimulation of the affected nerve branches derived to the shoulder. The soft robotic device is mounted on the neonate’s upper limb and torso using hypoallergenic, non-woven bands, focusing specifically on the external-internal rotation of the shoulder during its operation.

The JHH Pacemakers project aims to develop a training simulator for nurses to practice using external pacemakers. The solution includes a handheld electronic prototype mimicking a real pacemaker, featuring knobs, buttons, and sensor lights, connected wirelessly to an interactive website. The website offers modules with step-by-step simulations, real-time EKG monitoring, and a points-based scoring system to evaluate nurse proficiency. Key features include short quizzes, error feedback, and scenario-based training for conditions like tachycardia. The project addresses gaps in current training methods, which lack hands-on, interactive elements. The final prototype integrates hardware (Raspberry Pi, encoders, buttons) with software (React-based interface) to provide a realistic, user-friendly training tool. The goal is to enhance nurse confidence and competency in pacemaker management through immersive, practical learning.
