本文对盲文阅读触觉传感系统的研制进行了研究。触觉传感器使用PVDF(聚偏氟乙烯)薄膜作为感觉材料。传感器连接到由直流伺服电机驱动的滑块上，并以恒定速度在一串盲文上滑动以获得传感器输出。提出了一种盲文识别系统。在识别实验中，验证传感器系统是否具有足够的性能来正确识别字母串。实验结果表明，该传感器和传感器系统对盲文的识别是有效的。
This paper is a study on the development of a tactile sensor system for reading Braille. The tactile sensor uses a PVDF (polyvinylidene fluoride) film as the sensory material. The sensor is attached to a slider driven by a DC servomotor and it is slid over a string of Braille with a constant speed to obtain the sensor output. A recognition system of Braille is proposed. In a recognition experiment, the sensor system is verified as to whether it has enough performance to recognize a string of letters appropriately. The obtained result shows that the proposed sensor and sensor system are effective to recognize Braille.
