Raindrop sensor; Flexible electronics; Laser ablation.Abstract
At present, raindrop sensors are widely used in automotive automatic wiper systems, intelligent lighting systems and intelligent sunroof systems. Ability to detect rainwater in real-time and quickly start up other equipment. Different raindrop sensors have different characteristics and applications. Those who work outside are susceptible to environmental pollution and damage. Flexible electronic products can be freely bent, wound and folded, which perfectly adapts to various space layout needs. These products not only exhibit more flexible bending characteristics, but also have excellent shape adaptability and ductility. It can well deal with the problems of easy damage to the external raindrop sensor and space layout. In this project, the method of rapid production of circuits on the surface of polyimide by laser ablation method is used to draw the circuit diagram of the raindrop sensor, then the flexible material is soaked to make it ion exchanged, and then the laser engraving machine is used for laser ablation to form a circuit, and finally a flexible raindrop sensor is prepared. The results show that the prepared flexible raindrop sensor has the functions and characteristics of traditional raindrop sensor, and also has a certain degree of flexibility.
