基于摩擦纳米发电机的驾驶行为无干扰信息获取研究

Interference-Free Monitoring of Driving Behavior Based on Triboelectric Nanogenerators

开发了可伸缩的聚丙烯酰胺(PAAM)-licl基摩擦纳米发电机(PL-TENG)和具有铝(AI)-Kapton摩擦层结构的摩擦纳米发电机(AK-TENG),用于驾驶人的驾驶行为监测.PL-TENG具有体积小、质量轻、弹性好、透明度高、生物相容性好、无创、耐用、生产简单、成本低等优点.将PL-TENG贴在人体皮肤表面不会影响人体的舒适度,可在不干扰正常驾驶的情况下,获取驾驶人头部和面部的微小动作信息.AK-TENG具有高灵敏度和一定的柔性,相比于普通摩擦纳米发电机的结构更加坚固稳定且不易损坏,用于获取驾驶人在转向盘和踏板上的驾驶操作行为特征.本文利用PL-TENG和AK-TENG获取驾驶行为信息数据,获取驾驶人的驾驶状态和操作行为特征,同时也为智能交通系统中高灵敏度自供电传感器的设计提供了新的思路.

In this paper,a stretchable polyacrylamide(PAAM)-LiCl-based Triboelectric Nanogenerator(PL-TENG)and a Triboelectric Nanogenerators with aluminum(AI)-Kapton friction layer structure have been developed for drivers driving behavior monitoring.PL-TENG has the advantages of small size,light weight,good elasticity,high transparency,good biocompatibility,non-invasiveness,durability,simple production,and low cost.Sticking PL-TENG on the surface of the human skin will not affect the comfort of the human body,and can obtain the driver s head and face movement information without causing interference to the driver s normal driving.AK-TENG has high sensitivity and a certain degree of flexibility.It is stronger and more stable than ordinary Triboelectric Nanogenerators and is not easily damaged.It is used to obtain the driver s driving behavior data on the steering wheel and pedals.In this paper,PL-TENG and AK-TENG are used to obtain driving behavior information data to monitor the driver s condition and operating behavior.At the same time,it also provides a new idea for the design of high-sensitivity self-powered sensors in intelligent transportation systems.
