The coil of an electronic pen is an important component and essential part of an electronic pen. Its advantage is that it does not require carrying a battery and accumulates energy through electromagnetic induction. And digitization is one of its major features. The pen and antenna board transmit pressure sensing data through a digital protocol, which has the great advantages of high accuracy and good stability.
The smart pen coil is mainly used in touch sensitive mobile phones, computer electronic devices, conference equipment, drawing equipment, etc. with capacitive touch screens, and should be applied in fields such as conferences, teaching, healthcare, and automotive. With the advent of the Internet AI era, the application market of electronic pen will further increase in the future.
