一个新的触觉传感器配置的性能数据。该传感器是基于磁阻（MR）技术，但采用了专利的蛇形路径元件结构，提供了广泛的优势，比以前考虑的设计。以前的工作MR触觉传感器没有办法在换能器级的传感器优化的问题。通过强调自下而上的设计方法，可以开发出各种不同应用的传感器。灵敏度是触觉传感器设计中的关键特征。这是可以准确检测到的最小可检测力变化的度量。对高信噪比的要求表明需要高元件电阻、使用AC磁场和小几何尺寸（像素分辨率）。<>
Performance data on a new tactile sensor configuration are presented. The sensor is based on magnetoresistive (MR) technology but incorporates a patented serpentine path element structure which offers a wide range of advantages over previously considered designs. Previous work on MR tactile sensors did not approach the problem of sensor optimization at the transducer level. By placing the emphasis on the bottom-up method of design, a wide range of sensors for different applications could be developed. Sensitivity is a key feature in tactile sensor design. This is a measure of the minimum detectable force change that can be accurately detected. The requirement for high signal-to-noise ratios indicates the need for high element resistances, the use of AC magnetic fields, and small geometric size (pixel resolution).<>
