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

LIQUID CRYSTALS Introduction What are Liquid crystals ? Its History & Discovery Any of various liquids in which molecules are regularly arrayed like a solid crystal along one or two dimensions‚ but are free in the other dimensions as with typical liquids. Liquid crystals often display unusual and often manipulable optical properties such as anisotropic scattering. They can be divided into two classes‚ Thermo tropic(nematic‚ chiral nematic‚ and smectic.) and Lyotropic. Transitions to thermotropic

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
