Capacitive pen is the use of conductive material having conductive properties for capacitive touch screen complete with interactive pen operation. Capacitive touch pen for capacitive touch screen mobile phones, computers and other electronic equipment.

1: How it works

Capacitive touch screen is the use of the body's current sensing work. It is a four-layer composite glass screen, the inner surface of the glass panel and sandwich coated with a layer ITO (ie coated conductive glass), the outermost layer is a thin layer of silica glass protective layer. ITO coating as a face, leads to four electrodes on the four corners of the inner layer of ITO as a shield in order to ensure a good working environment.

When the fingers touch the metal layer, the electric field due to the human user and the touch screen surface of a coupling capacitor for high-frequency current, capacitance is directly conductor, so your fingers away from the contact point of a small current. This current flows from the electrode, respectively, on the four corners of the touch screen, and a current flows through four electrodes from the four corners of the finger to the proportional controller through the accurate calculation of the four current ratio, come touch points location information.

Capacitive pen is the use of conductive material to mimic the human body (usually a finger) to complete an auxiliary device man-machine dialogue.

2: Production Method

1: The sponge cut 6x6x15mm strips, cut the tip angle convenient to hold a pen
2: Use double-sided tape wrapped sponge, fixed on the pen, writing side must be smooth
3: cut 1.5x5mm cigarette foil strip, foil and write the middle first side glue, sponge down the foil and then stick to the cartridge, the last two measurement surfaces glued
4: so can conduct electricity, refills posted double sided tape, wrapped in tinfoil.

3: The main purpose

For touch capacitive touch screen mobile phones, computers and other electronic equipment.
