    Touch screen is sensitive to the moisture and electric charge from your skin. The moisture on your skin carries small electrical pulses from your body to the screen, these pulses are picked up by sensors allowing the processor to identify where your finger is. In short...if it can't transmit a small charge to the screen it won't work.
