This paper introduces a novel capacitive sensor array designed for tactile perception applications. Utilizing an all-in-one inkjet deposition printing process, the exhibited exceptional flexibility and accuracy. With resolution of up to 32.7 dpi, was capable capturing fine details touch inputs, making it suitable applications requiring high spatial resolution. The design incorporates two multiplexers achieve scanning rate 100 Hz, ensuring rapid responsive data acquisition that is essential real-time feedback in interactive applications, such as gesture recognition haptic interfaces. To evaluate performance array, experiment involved handwritten number conducted. results demonstrated accurately captured fingertip inputs with precision. When combined Auxiliary Classifier Generative Adversarial Network (ACGAN) algorithm, system achieved accuracy 98% various numbers from "0" "9". These show potential advanced human-computer interaction
