Background

With the development of scientific technology, printed electronics have been widely used in various fields such as chemical monitoring, life science, and optical detection. The current technology for processing microstructures on a plane is well established, such as the most common screen printing technology, transfer printing technology, etc. However, the two-dimensional structure has many limitations in the field of sensors, such as too large area and difficulty in miniaturization. The micro-spherical structure has the advantages of large surface area and small volume, and particularly in the field of implantable sensors, the micro-spherical structure can often occupy smaller volume to realize required functions.

The common two-dimensional processing technology cannot realize the micro-structure processing of the micro-sphere, and the current processing on the micro-sphere mostly adopts the modes of electrostatic adsorption and vacuum evaporation. However, both of these two methods cannot accurately control the distribution of the microstructure pattern on the microsphere, and cannot realize the design and processing of the customized structure.

Inkjet printing is also a process that can process two-dimensional structures, and inkjet printing technology has attracted attention due to its advantages and maturity of technology, and is widely used to print electronic circuits. The ink-jet printing technology can process patterns in a designated area according to instructions, and is an ideal process for processing the micro-spherical structure. However, at present, the difficulty in accurately implementing the processing of the micro-structure on the micro-sphere or the complex curved surface is very high, especially when the target object has a small volume and the printing precision requirement is very high.
