PIEZOELECTRICITY AND APPLICATIONS Piezoelectricity is the ability of some materials such as crystals and certain ceramics‚ to generate an electric potential in response to applied mechanical stress or heat. If the piezo crystals are not short-circuited‚ the applied charge induces a voltage across the material. The word Piezo is derived from the Greek “Piezein”‚ which means to squeeze or press. The piezo material exhibits both “Direct piezo electric effect” as well as ‘Converse piezo electric

Piezoelectric crystals are one of many small scale energy sources. Whenever piezoelectric crystals are mechanically deformed or subject to vibration they generate a small voltage‚ commonly know as piezoelectricity. This form of renewable energy is not ideally suited to an industrial situation. The ability of certain crystals to generate Piezoelectricity in response to applied mechanical stress is reversible in that piezoelectric crystals‚ when subjected to an externally applied voltage‚ can change

Crystals form in the depths of the Earth to the extension of the clouds in sky. Some think that crystals elude the sight of people’s eyes everyday in life‚ but they are everywhere including ingredients for food‚ construction materials‚ and even in ice-cold weather. The crystals in this experiment are ammonia-generated crystals that can be created right in a home. The experiment will be testing the different effects and products on crystals in different temperatures and forms of light. Different measurements
