The piezoresistive pressure sensor, or silicon cell. This type of pressure sensor consists of a micro-machined silicon diaphragm with piezoresistive strain gauges diffused into it, fused to a silicon or glass backplate. The resistors have a value of approx. 3.5 kOhm.
Quick Answer. The basic skills needed to play volleyball are serving, passing, setting, spiking, blocking and digging. Proper technique and form are essential to getting the ball in the desired location and to building up speed and power.
Setting is another skill that is specific to volleyball. In order to avoid holding the ball, a set is a brief hit with tops of ones fingers that sort of bounces it up in the air. Not a good offensive hit, setting is most often used when a player's team member wishes to spike the ball.
