Pencil-on-paper electronics has gained growing interests as cost-effective, ecofriendly, flexible, and light-weight devices for various applications. In this letter, a flexible keypad employing pencil-on-paper capacitive touch sensors is presented. Spiral-type interdigitated are interconnected via steel threads well graphite paths to constitute ten-button keypad. Passivation of the by means acrylic paint coating works protection against deterioration from bending, folding, extended usage. Backing with silicone provides extra durability. Sensor reading administered Arduino boards. The same manufacturing method used scale up system 44-button keyboard. Functionalities both systems successfully demonstrated, effectiveness passivation verified.
