人造电子皮肤（e-skin）包括布置在柔软的可重构表面上的柔性设备的集成矩阵。这些传感器必须感知外部物体与机器人或人类之间的物理交互空间。在各种类型的传感器中，柔性磁传感器和矩阵配置对于这种位置感测是优选的。然而，传感器矩阵必须有效地映射磁场，并对磁性物体的位置和运动进行实时编码。本文报道了一种磁阻传感器矩阵系统，包括一个2 × 4阵列的磁阻传感器，一个自举有机移位寄存器驱动的传感器矩阵，和有机信号放大器集成在一个单一的不可感知的平台。由于采用了有机放大器，该系统具有很高的磁灵敏度。此外，移位寄存器实现了2D磁场分布的实时映射。
Artificial electronic skins (e-skins) comprise an integrated matrix of flexible devices arranged on a soft, reconfigurable surface. These sensors must perceive physical interaction spaces between external objects and robots or humans. Among various types of sensors, flexible magnetic sensors and the matrix configuration are preferable for such position sensing. However, sensor matrices must efficiently map the magnetic field with real-time encoding of the positions and motions of magnetic objects. This paper reports an ultrathin magnetic sensor matrix system comprising a 2 x 4 array of magnetoresistance sensors, a bootstrap organic shift register driving the sensor matrix, and organic signal amplifiers integrated within a single imperceptible platform. The system demonstrates high magnetic sensitivity owing to the use of organic amplifiers. Moreover, the shift register enabled real-time mapping of 2D magnetic field distribution.
