1. An ink cartridge for a pen comprising:

  • a cartridge having a writing tip;

    an ink reservoir contained within the cartridge and communicating with the writing tip for allowing ink transfer from the ink reservoir through the writing tip;

    a microelectromechanical (MEMS) accelerometer sensor mounted within the cartridge in a position for generating an acceleration signal indicative of movement of said writing tip; and

    a transmitter operatively connected to said microelectromechanical (MEMS) accelerometer sensor for receiving the acceleration signal from said microelectromechanical (MEMS) accelerometer sensor and transmitting the acceleration signal to a remote processor where the acceleration signal is processed for recreating handwritten signatures and communications.
