Graphite-on-Paper Based Capacitive Touch Arrays for Wireless Mouse Curser Control Pad

Abstract

In the era of wireless technology, the demand for cost-effective and versatile solutions has grown exponentially. This study presents a design for a wireless mouse pad that leverages graphite-sensing arrays on paper to create a capacitive sensor-based touchpad. By integrating the Espressif Systems ESP32 microcontroller, we established wireless cursor control for both laptops and mobile devices. The innovation introduced here extends the application possibilities of paper-based sensors, particularly those involving graphite-on-paper (GoP) technology. This advancement holds great promise for diverse fields, including soft robotics, healthcare, and biomedicine.
