Flexible electronics refers to the utilization of pliable plastic substrates in the construction of elastic and bendable electrical circuits. Unlike conventional semiconductors and glass substrates, flexible electronics open up possibilities for entirely new product designs. This innovation hinges on the fabrication of electronic components on flexible plastic substrates like transparent conductive polyester film or polyimide, facilitating the assembly of electronic circuits. Remarkably, the same components employed in crafting rigid printed circuit boards can be repurposed for fashioning flexible electronic assemblies, allowing the board to flex and conform to desired shapes. In an alternative approach to flexible electronics, the standard silicon substrate must undergo thinning to a few tens of micrometers through etching processes, thereby achieving a bending radius of less than 5mm. The burgeoning growth of wearable technology, spanning global positioning systems (GPS), communication devices, health monitoring systems, and military applications, has propelled the rapid expansion of flexible antenna design and modeling. This surge reflects the pivotal role that flexible electronics play in enabling the evolution of these crucial industries.
