In 1880, while performing experiments with tourmaline, quartz, topaz, cane sugar and Rochelle salt crystals, Pierre and Jacques Curie discovered that when mechanical stress was applied to a crystal, faint electric charges developed on the surface of that crystal. The prefix ‘piezo’ comes from the Greek piezein, which means to squeeze or press. As a result, piezoelectricity is electrical charge that is produced on certain materials when that material is subjected to an applied mechanical ...

Technical article: active heave — how to accumulate more energy savings downloadweblink

Bosch RexrothThu, 26 Mar 2015

With oil becoming harder to exploit and prices increasing, operations are moving into deeper waters. Active-heave users need to move towards more energy-efficient solutions as subsea activity needs more power to deploy the equipment to reach these hidden depths. Steve Smith, marine and offshore sector manager at Bosch Rexroth, says by innovative system design and integrating accumulators into the active-heave compensation control process, end users could achieve energy savings of up ...

White paper: mechanical structure for piezoelectric harvester application downloadweblink

Cedrat Technologies S.AMon, 9 Mar 2015

A mechanical structure based on serial stacking of level arm has been designed in order to amplify the ingoing force of the harvester system. The outgoing force is applied on the smart material. The deformation of the mechanical structure is based on flexural pivots using four truncated circular collars. The last amplification is based on the amplified piezoelectric actuator (APA) shell from Cedrat Technologies.
