Device and Method for Healing Wounds

This technology is a device that uses electrical activity to facilitate the wound healing process while protecting the wound. The bandage is made of an electroactive material (see figure) that is stimulated by the heat of the body and the pressure of cell growth, thus no external power source is required.

Relativistic Ion Tracks (RITRACKS)

Once astronauts venture beyond Earth’s protective atmosphere, they are exposed to the high-energy charged particles of galactic cosmic rays (GCR) and solar particle events (SPE), and secondary protons and neutrons. GCR are composed of ions, the great majority of which are protons (≈87%) and helium nuclei...

Using a Blood Clot in Microfluidic Valving Applications

This type of valve is satisfactory for most microfluidic applications for on-chip blood analysis.

The lack of reliable microvalves impedes many lab-on-a-chip applications for blood analysis. On the other hand, blood clotting — the formation of solid blood aggregate to stop...

Drug-Encapsulated Prosthetic Enhancement

This invention places a drug delivery system inside a prosthetic implant to circumvent the physical issues encountered after fitting the implant. Implants being relatively large in size would be able to house the drug-carrying device inside them without compromising the structural integrity or the...

Ultrasound Competence Test Metrics

Diagnostic medical ultrasound requires psychomotor skill in image acquisition and cognitive skill in image interpretation. There is a lack of an objective, quantitative, and standardized method to assess psychomotor skill. In traditional radiology and cardiology training programs, physicians are certified based...

Bayesian Sleep Fusion

To ensure mission success, astronauts must maintain a high level of performance, even when work-rest schedules result in chronic sleep restriction and circadian misalignment, both of which can contribute to fatigue and performance deficits unless effective countermeasures are used. The overarching goal of this project is to...
