What is the difference between the Capacitive Touchscreen and Resistive Touchscreen? Which is better?

How do capacitive accelerometers work in touchscreen devices?

• Please explain to me what capacitive accelerometers actually are, what they are for, types of devices they are found in, and answer the following questions.Are capacitive accelerometers responsible for allowing capacitive touchscreens to work or are they not connected that way? How do capacitive accelerometers work in touchscreen devices and how does it function as part of the device? What are the dis/advantages of capacitive accelerometers? How much do they cost & what social/environmental impacts do capacitive accelerometers do they have?

• Answer:

  Capacitive accelerometers and capacitive touch sensing are unrelated technologies. The accelerometers use the displacement of a small beam (usually a MEMS structure) to produce a capacitive variation proportional to acceleration. cap touch sensing has nothing to do with acceleration at all, but relies on changes in a capacitive sensing grid to locate the position of one or more fingers.
