Active Electrostatic (Active ES) technology enables a precise, power-efficient digital pen input experience.
30 years of perfection
Perfected and improved for over 30 years, Wacom’ s Active ES digital pen technology enables precise and intuitive input that lets people focus on their creations. From the pen-tip material, carefully selected to match each writing surface, to state-of-the-art signal noise management and pressure sensing techniques, every aspect of our technology is painstakingly optimized to achieve the familiar Wacom feeling.
How Active ES works
Wacom’s Active ES is an electrostatic capacitive pen coupling technology. It consists of a display containing a sensor with multiple electrostatic grids arranged at right angles to one another, that interacts with a Wacom digital pen. One sensor grid and the pen act as the transmitting unit that generates an electrical field; the other grids act as receiving units. The pen's position is identified based on differences in the charge amount detected on each sensor grid receiving unit.
