Conductive ink is a special type of ink that can conduct electricity. It is made from materials like silver, copper, or carbon, which allow it to transmit electrical signals. This ink is often used in printed electronics, such as flexible circuits and sensors, enabling the creation of lightweight and adaptable devices. One of the main advantages of conductive ink is its ability to be printed on various surfaces, including paper, plastic, and fabric. This versatility opens up new possibilities for innovative applications, such as wearable technology and smart packaging, making electronics more accessible and customizable.
