Metallized paper is patterned to create touch pads of arrayed buttons that are sensitive to contact with both bare and gloved fingers. The paper-based keypad detects the change in capacitance associated with the touch of a finger to one of its buttons. Mounted on an alarmed cardboard box, the keypad requires the appropriate sequence of touches to disarm the system.
金属化纸张经过图案设计，可制成带有排列按钮的触摸垫，能够感应到裸指和戴手套的手指的接触。基于纸张的键盘通过检测与手指触摸其按钮之一相关的电容变化来检测触摸。将键盘安装在带警报的纸板箱上，需要按正确的触摸顺序才能解除系统的警戒。
