Abstract: A digital pressure sensitive electromagnetic pen for writing and drawing on a touchpad is disclosed. The digital pressure sensitive pen comprising a pen core extending through a coil, a clamp casing, into a pen core support where the pen core is secured within a polygonal notch. The pressure sensitive pen further comprises a fixing casing inside which a conductible rubber, a coil circuit board, and an elastic element are placed. On the coil circuit board, spiral circuit arrangement is printed on the side facing toward the conductible rubber. The other side of the coil circuit board is connected to a processing board. When the pen is not used, there is no contact between the conductible rubber and the coil circuit board. When the pen of the present invention is used, there is writing force exerted on the pen core which moves the pen core support upwards and consequently pushes the conductible rubber against the coil circuit board and deforms the rubber.
