Piezoelectric accelerometers also involve a mass and a spring, but instead of just having a pen that draws a line, the mass is pressed against a piezoelectric crystal while it rests. From there, when the force causes the outer casing to move and the spring to stretch, the crystal gets squeezed by the mass and this squeezing produces a tiny electric voltage that translates to the
