Magmedics seeks to develop a non-intrusive patient wearable device that actively reduces patient blood pressure by changing the viscosity of blood. In several studies, researchers have demonstrated that a large magnetic field applied to a person wrist and parallel to the direction of blood flow was able to reduce blood viscosity, and therefore blood pressure, up to 30%. However, device size, power generation, and cooling are all significant engineering obstacles and limit the ease of use of this large electromagnet. Magmedics has designed and simulated a proof of concept device that is capable of generating magnetic axial fields greater than 1.2 T, which is necessary to overcome the ambient thermal noise of one’s body temperature, while being completely composed of permanent magnets. Generating a field greater than 1 T out of only permanent magnets is not straight forward due to the magnetic saturation of the materials.
In the United States, heart disease is the No. 1 cause of death, primarily due to hypertension. Based on AHA’s report, the death rate due to high blood pressure has increased by 38% from 2005 to 2015. If untreated, hypertension can raise the chance of heart attacks and strokes. Magmedics seeks to reduce the number of deaths related to heart disease by providing an accessible alternative to antihypertension drugs, which will increase overall patient compliance.
What I Will Do With $5,000
With an additional $5k, we will create a novel jig that will be used to hold the strong magnets in place while they can be adhered together. The final result will be an efficient and safe method for assembling the magnets in order to create a large axial field. Investigation of the magnetic field orientation and the shape of the magnets will illuminate the best possible way to fabricate a prototype such that the largest field possible is achieved with the fewest number of permanent magnets.
