Problems solved by technology

In addition to being expensive, quartz substrates and silicon substrates have the same disadvantages as glass substrates, such as fragile, relatively heavy, inconvenient to carry, and non-degradable; although plastic substrates have the advantages of flexibility and light weight, most of them are non-degradable Or it is toxic and will cause great harm to the environment and organisms, which greatly limits the application range of the device
