The smart pen coil uses the working principle of EMR electromagnetic induction technology, EMR is called Elector-Magnetic Resonance, that is, electromagnetic induction. EMR technology contains two important parts, one is the electromagnetic induction plate, the other is the electromagnetic pen. Passive wireless electromagnetic pressure pen technology is currently used in the smart pen market and a strong stability of a technology, its core advantage is that you can use any ordinary paper for writing, and there is no battery in the electromagnetic pen, no need to charge, stable data transmission, excellent grip, very low loss rate. It can not only save the cost of late consumables, but also has strong convenience and practicality.
