Its resolution is very high and therefore with very little change in supply voltage it can be either converted or detected for linear motion. It is possible to attain very high actuation force without any loss of precision. You can get very high response time even below one milli second. Since there is no moving part involved hence there is no question of friction or wear and tear etc. and therefore after 500 million cycles too there is no fatigue or aging possible.
