SBIR Phase I: No Preparation, Flexible, Dry Physiological Recording Electrodes

这个小企业创新研究（SBIR）第一阶段项目将开发一种新颖、灵活、干燥的生理记录电极，该电极符合非平面表面，不需要大量的表面准备或导电凝胶来实现与身体的低阻抗界面。这种创新的电极将采用微加工技术制造，成本低廉，价格与现有的商业电极相比具有竞争力，尽管它的性能和特点有所增强。提出的干电极将在生物医学研究和医学的所有领域提供实质性的改进，涉及使用电生理电位，如脑电图，肌电图，眼电图和心电信号。与现有的商用电极相比，这种独特的电极特别适合于长期和多电极生理监测，因为多个电极可以很容易地用一个公共连接器制成一个单一阵列，从而简化了应用。此外，通过提供与身体的低阻抗接口，该电极将消除对电解凝胶的需要或在应用电极之前磨损皮肤的需要。该项目的商业应用将直接遵循新型电极（轨道研究干生理记录电极）的开发，该电极旨在改善电生理信号质量（用于脑电图，肌电信号，ecg或EOGs），消除现有电极常见的严重副作用和信号恶化，并具有竞争力的价格。通过在不增加额外成本的情况下提高生活质量，这种生物医学创新有望带来新的长期监测应用。

This Small Business Innovative Research (SBIR) Phase I project will develop a novel and flexible, dry, physiological recording electrode that conforms to non-planar surfaces and does not require extensive surface preparation or conductive gels to achieve a low impedance interface with the body. This innovative electrode will be fabricated inexpensively using microfabrication techniques and priced competitively with existing commercial electrodes despite its enhanced performance and features. The proposed dry electrode will provide substantial improvement in all areas of biomedical research and medicine that involve use of electro- physiological potentials such as EEG, EMG, EOG, and ECG signals. This unique electrode is particularly well suited for long-term and multiple electrode physiological monitoring as compared to existing commercial electrodes,since multiple electrodes can be easily fabricated into a single array with a common connector, thereby simplifying application. Additionally, by providing a low impedance interface with the body, this electrode will eliminate the need for an electrolytic gel or the need to abrade the skin prior to applying the electrode. The commercial applications of this project will follow directly from the development of the novel electrode (Orbital Research Dry Physiological Recording Electrode) that seeks to improve electro-physiological signal quality (for EEGs, EMGs, ECGs or EOGs), eliminates the harsh side effects and signal deterioration common with existing electrodes and is competitively priced. By enhancing quality of life at no additional cost, this biomedical innovation is expected to lead to new long-term monitoring applications.
