开发用于特定生物医学应用的新型优化电极可以显著提高感测信号的质量。同心环形电极已经显示出提供比常规盘电极的空间分辨率更高的空间分辨率。具有不同电极尺寸和配置（单极、双极等）的传感器提供同时记录的方法将非常有助于研究最佳信号感测布置。一个5极电极与一个内部的磁盘和四个同心环的不同大小的开发和测试的表面肠肌电记录从健康人。为了更好地适应弯曲的身体表面，将电极丝网印刷到柔性聚酯基底上。为了便于临床使用，它是自粘性的，包含一个连接器，可以进行干或湿（凝胶）记录。结果表明，它是一个通用的电极，可以评估最佳配置的识别肠道慢波和拒绝不必要的干扰。具有30 mm外环直径、无泡沫粘合剂材料和电解质凝胶的双极同心记录给出了最佳结果。
Developing new types of optimized electrodes for specific biomedical applications can substantially improve the quality of the sensed signals. Concentric ring electrodes have been shown to provide enhanced spatial resolution to that of conventional disc electrodes. A sensor with different electrode sizes and configurations (monopolar, bipolar, etc.) that provides simultaneous records would be very helpful for studying the best signal-sensing arrangement. A 5-pole electrode with an inner disc and four concentric rings of different sizes was developed and tested on surface intestinal myoelectrical recordings from healthy humans. For good adaptation to a curved body surface, the electrode was screen-printed onto a flexible polyester substrate. To facilitate clinical use, it is self-adhesive, incorporates a single connector and can perform dry or wet (with gel) recordings. The results show it to be a versatile electrode that can evaluate the optimal configuration for the identification of the intestinal slow wave and reject undesired interference. A bipolar concentric record with an outer ring diameter of 30 mm, a foam-free adhesive material, and electrolytic gel gave the best results.
