Other Piezoelectric applications
High-voltage sources
In lighters or portable sparkers with a piezo fuze a sudden and strong pressure is used in order to produce a short high voltage. The spark then ignites the gas.
Frequency standard
Reduction of vibrations
Piezoelements are used in music for acoustic instruments. They are inserted in stringed instruments such as guitar, violin or Mandoline. The dynamic deformation of the instrument (vibration of the cords) is converted into a small alternating voltage.
