Abstract

The invention discloses a non-contact flexible transparent sensor and a preparation method thereof, and belongs to the field of flexible sensors. The conductive induction layer is deposited on the surface of the insulation supporting layer, and the contact surface of the insulation supporting layer and the conductive induction layer is a composite rough surface; redistribution of charges on the surface of the sensing layer caused by hand movement is detected by adopting four ends, so that non-contact sensing and control based on gestures are realized. The double-layer structure has universality, the sensing layer can be made of conductive films such as indium tin oxide, copper and the like, and the supporting layer can be made of glass, quartz, a display screen and the like. On the other hand, a rough structure is prepared on the surface of the sensing layer through a plasma etching process, so that the specific surface area is increased, the output signal of the sensor is greatly improved, and higher sensitivity is provided for the near-field sensor.

Description

technical field

[0001] The invention belongs to the field of flexible sensors, and relates to a non-contact flexible transparent sensor and a preparation method thereof. Background technique

[0002] Non-contact sensing methods have received extensive attention due to their great potential in human-computer interaction, health monitoring, and hospital healthcare. Compared with contact sensing, non-contact sensing is more convenient in some occasions, such as wireless The interaction of physical contact may help to reduce the chance of spreading pathogens such as the COVID-19 virus, thus controlling electronic devices through contactless methods is a promising research area.

[0003] At present, there are two main problems in the non-contact sensing method that uses human body static electricity as the natural signal source: one is that the output induction signal is usually weak due to the limited charge carried by the human body, and it is difficult to monitor. Another is ...
