1, Tin foil: Tin foil is a conductive material. When it is made into a pen shape and touches the touch screen, it can conduct the weak current of the human body like a finger and form an effective capacitive coupling with the screen. Because the surface of tin foil is smooth and the texture is soft, it generally does not cause physical damage to the screen.

2. Chopsticks: Chopsticks themselves are not conductive, but they can also be used as temporary touch-sensitive pens if they are wrapped with conductive materials. Chopsticks provide a shape advantage that is convenient to hold and operate, especially after being wrapped with conductive objects, which can simulate the effect of fingers touching the screen.
