Stretchable electronic device for monitoring eye movement behaviors of driver and preparation method thereof

Abstract

The invention discloses a driver eye movement behavior real-time monitoring device, which comprises a stretchable elastic substrate, and a sensing unit such as a temperature sensing unit, a sweating sensing unit and an electrooculogram sensing unit is integrated on the elastic substrate. The stretchable eye movement behavior monitoring device is attached to the surfaces of the parts such as the corners of the eyes or the forehead to sense and record physiological signals of a driver. The invention further provides a preparation method of the driver eye movement behavior monitoring device, andan electronic skin system compatible with the flexible skin is obtained. The eye movement behavior monitoring device is attached to the eye corners, normal driving of a driver is not affected, physiological signals of the driver are obtained in real time, and the portability of the eye movement behavior monitoring device is greatly improved.

Description

technical field [0001] The invention relates to the fields of flexible electronics and wearable electronics, in particular to a stretchable electronic skin design and a preparation method for eye movement monitoring of drivers. Background technique [0002] Stretchable electronics is an important development trend of flexible electronics at present. It has unique advantages in many cases and has excellent deformation performance. Stretchable electronic devices have good stretch deformation ability, actively adapt to the flexible skin surface and Maintain conformal contact, reduce the movement slip between the electronic device and the skin surface, reduce the static electricity caused by movement friction, and improve the stability of the electronic device to record physiological signals. Stretchable electronic devices are pasted on the soft skin surface to record the driver's physiological information and monitor the driver's eye movement behavior. It will be more widely us...
