中文摘要：随着智能可穿戴技术的快速发展,柔性电容式传感器因其制备工艺简单及优良的电学性能,在健康监测、人机交互、电子皮肤等领域展现出广阔的应用前景。本文围绕提升电容式传感器的检测范围和耐久性为目标,提出了一种基于聚二甲基硅氧烷(PDMS)和可膨胀微球复合介电层的仿生皮肤褶皱结构的电容式传感器。用SEM分析了介电层的结构形貌,并研究了该传感器的电学性能和人体适用性。结果表明:电容式传感器具有较宽的检测范围(0~242 kPa)、高灵敏度(0.0079 kPa^(?1))、快速响应时间(230 ms)以及优异的稳定耐久性(9500次循环);同时,还具有较好的非接触感测性能,其非接触灵敏度为0.59%/cm。在实际应用中,该传感器可用于监测手指、手腕、膝盖等关节的弯曲运动,以及眨眼、张口等细微的生理信号。该电容式传感器在运动监测和健康监测领域具有潜在的应用价值。

外文摘要：With the rapid development of intelligent wearable technology,flexible capacitive sensors have shown broad application prospects in fields such as health monitoring,human-computer interaction,and electronic skin due to their simple preparation process and excellent electrical property.In order to improve the detection range and durability of the capacitive sensors,a capacitive sensor based on polydimethylsiloxane(PDMS)composite dielectric layer and expandable microsphere imitating the skin wrinkle structure is proposed.The structural morphology of the dielectric layer was evaluated by SEM and the electrical properties and human suitability of the sensor were investigated.The results show that the capacitive sensor has a wide detection range(0-242 kPa),high sensitivity(0.0079 kPa^(?1)),fast response time(230 ms),and excellent stable durability(9500 cycles).It also has good non-contact sensing performance with a non-contact sensitivity of 0.59%/cm.In practical applications,this sensor can accurately monitor bending movements of joints such as fingers,wrists and knees,as well as subtle physiological signals such as blinking and opening the mouth.The capacitive sensor has potential applications in the field of motion monitoring and health monitoring.
