摘要: 本研究从绿色工程理念出发，采用碳化叶脉纤维为传感介质制备了电阻式压力传感器，并测试了其传感性能。该压力传感器可以承受的最大压强为200 kPa，电阻变化率最高可达105%，并且可以在500次的循环压力测试下保持稳定良好的性能，承受压力时的响应时间在40 ms以内。另外，该压力传感器的传感介质来自天然树叶，制作方法简单易行，成本低廉，在需要较大压力的使用环境中具有良好的应用潜力。
Abstract: Based on the concept of green engineering, a resistance type pressure sensor has been fabricated using carbonized leaf vein fibers as sensing medium. The performance of the sensor was also tested. It was found that the maximum pressure which the sensor can withstand is 200 kPa, and the resistance change rate reaches up to 105%. The sensor maintained stable performance during a 500 cycle pressure test. The response time of the pressure sensor is within 40 ms. Furthermore, the sensing medium is made from the natural leaves, and the method for fabricating the sensor is simple with low cost, indicating potential applications of the sensor in need of a larger pressure working environment.
