摘　　要：利用柔性传感器和微控制单元,设计并实现了可集成于服装进行跨平台音乐控制的无线控制器,为制备结构简单、成本低廉的柔性可穿戴传感系统提供了新的思路。基于柔性织物传感材料,提出了一种结构简单的传感器件作为控制器的按键,具有良好的穿戴舒适性。传感器件能够感知15kPa以内的手指按压动作。使用ESP32作为微控制单元,用于传感信号采集与数据处理。利用ESP32内部集成的蓝牙芯片,控制器可以与不同平台的终端设备连接进行无线数据传输。结果显示,所制备的无线音乐控制器与Windows电脑端及安卓手机端均可以进行稳定连接,传感器对手指按压识别准确率为99.7%,表明了柔性织物传感器在可穿戴设备领域具有广阔的应用前景。Design and implementation of a wireless flexible wearable music controller was based on flexible fabric sensor and micro-control unit. The controller can be integrated into clothing, which provides a new idea for the preparation of a flexible wearable sensor system with simple structure and low cost. The controller buttons made of flexible fabric sensors have good wearing comfort. A sensor device with a simple structure is proposed. The sensor device can sense finger pressing actions within 15 kPa. The micro control unit used by the controller is ESP32 which is used for sensor signal acquisition and data processing. Using the integrated Bluetooth chip inside the ESP32, the controller can connect different terminal devices across platforms for wireless data transmission. The results show that the wireless music controller made in this article can be connected stably with both the Windows computer and the Android mobile phone. The accuracy of the sensor’s recognition of finger pressing is 99.7%, shows that flexible fabric sensors have broad application prospects in the field of wearable devices.
