Homework Answers
Capacitive Sensor -- These type of sensors are based on the capacitive coupling and used for the detection of the conduction and also for the dielectric different from the air.
These sensors are made of different materials like copper , indium, tin oxide and pink ink.
These sensors used in the mobile phones, touchscreens, Digital audio players, tablet computers.
