    摘要： The skin preparation device and sensor of the present invention include an array of rigid tines. The tines serve to “self-prepare” the skin at each electrode site. These tines, when pressed against the skin, penetrate the stratum corneum, thereby reducing skin impedance and improving signal quality. A self-prepping device of the present invention is an optimized array of short non-conductive rigid tines in which the individual tines are created in a geometry that allows for a sharp point at the tip when molding, machining or etching is used as a method of fabrication. This non-conductive array with rigid penetrating structures may, therefore, be used in combination with a conductive medium, preferably an ionic conductive gel. In penetrating the stratum corneum, micro-conduits are created in the layers of the skin enabling the conductive medium to reach the low impedance layers and to transmit bioelectrical signals from the skin to the electrode surface. Such a self-prepping device can be readily mass produced using molding methods or possibly other manufacturing methods, thereby providing for a low cost means of achieving improved performance of the biopotential sensor. Additionally this invention includes the integration of this self-prepping device into a biopotential sensor comprising an array of one or more electrodes.

    摘要翻译： 本发明的皮肤制备装置和传感器包括刚性齿的阵列。 齿用于“自我准备”每个电极部位的皮肤。 这些尖齿当被压在皮肤上时，穿透角质层，从而减少皮肤阻抗并提高信号质量。 本发明的自制准备装置是一种优化的短非导电刚性尖齿阵列，其中单个尖齿以几何形状产生，当成型时，允许尖端处的尖锐点，加工或蚀刻用作方法 的制造。 因此，具有刚性穿透结构的这种非导电阵列可以与导电介质，优选离子导电凝胶组合使用。 在穿透角质层时，在皮肤层中产生微导管，使得导电介质能够到达低阻抗层并且将生物电信号从皮肤传输到电极表面。 这种自制准备装置可以使用模制方法或可能的其他制造方法容易地批量生产，从而提供实现生物电势传感器的改进性能的低成本手段。 此外，本发明包括将该自准备装置整合到包括一个或多个电极的阵列的生物电位传感器中。
