Development of Microneedle-Based Biosensing Systems

Microneedles are small sub-millimeter projections that allow for pain free access to the dermal layers of the skin. This allows for enhanced drug delivery and biosensing capabilities that are much more accessible and comfortable for the patient. This work aims to improve the capabilities of a solid metal microneedle system designed for use in electrical bio signal monitoring to enhance accuracy of the system while maintaining the simplicity of the current patch style electrodes used for electrocardiography (ECG), electromyography (EMG), etc. By utilizing an existing fabrication process for these microneedles, this work will study the impacts of array design, fabrication techniques, and surface modifications to improve system accuracy, leading to better patient outcomes, higher manufacturability, and increased reliability. Specifically this work will focus on the development of an electrode system for EMG analyses of patients with Parkinson’s disease.
