Application of mechanical stress to a piezo crystal generates a charge. Quoting from wikipedia, a 1 cm3 cube of quartz with 2 kN (500 lbf) of correctly applied force can produce a voltage of 12500 V. What happens when the crystal is exposed to a vacuum? Is the converse true? If the structural deformation occurs as a result of exposure to vacuum, is a voltage still generated?
