Abstract：
Abnormal oculomotor movements are known to be linked to various types of brain disorders, physical/mental shocks to the brain, and other neurological disorders, hence its monitoring can be developed into a simple but effective diagnostic tool. To overcome the limitations in the current eye-tracking system and electrooculography, a piezoelectric arrayed sensor system is developed using single-crystalline III-N thin-film transducers, which offers advantages of mechanical flexibility, biocompatibility, and high electromechanical conversion, for continuous monitoring of oculomotor movements by skin-attachable, safe, and highly sensitive sensors. The flexible piezoelectric eye movement sensor array (F-PEMSA), consisting of three transducers, is attached to the face temple area where it can be comfortably wearable and can detect the muscles\' activity associated with the eye motions. Output voltages from upper, mid, and lower sensors (transducers) on different temple areas generate discernable patterns of output voltage signals with different combinations of positive/negative signs and their relative magnitudes for the various movements of eyeballs including 8 directional (lateral, vertical, and diagonal) and two rotational movements, which enable various types of saccade and pursuit tests. The F-PEMSA can be used in clinical studies on the brain-eye relationship to evaluate the functional integrity of multiple brain systems and cognitive processes.
摘要：
众所周知，异常的动眼运动与各种类型的脑部疾病有关，对大脑的身体/精神冲击，和其他神经系统疾病，因此，它的监测可以发展成一个简单而有效的诊断工具。为了克服当前眼动追踪系统和眼电图的局限性，使用单晶III-N薄膜换能器开发了压电阵列传感器系统，它提供了机械灵活性的优点，生物相容性，和高机电转换，通过皮肤附着连续监测动眼运动，安全,和高度敏感的传感器。柔性压电眼动传感器阵列(F-PEMSA),由三个传感器组成，附着在面部太阳穴区域，它可以舒适地穿戴，并可以检测与眼睛运动相关的肌肉活动。输出电压从上，mid,和较低的传感器（传感器）在不同的太阳穴区域生成输出电压信号的可辨别的模式，具有不同的组合的正/负号和它们的相对大小的眼球的各种运动，包括8个方向（横向，垂直,和对角线)和两个旋转运动，可以进行各种类型的扫视和追踪测试。F-PEMSA可用于脑-眼关系的临床研究，以评估多个脑系统和认知过程的功能完整性。本文受版权保护。保留所有权利。
