all can contribute to additional variability
This two layer (bi-morph) piezoelectric actuator and sensor is unique to our other products in that each piezo layer is wired out individually to 4 wires
Extender motion on the order of microns to tens of microns
It has high motion per volt sensitivity but its upper temperature range is limited and its properties are more sensitive to temperature
the piece expands along the axis of polarization (thickness direction) and contracts perpendicular to the axis of polarization (radial direction)
Piezoelectric Extending Transducer (D220-H4BR-2513XE) Meta||Unit Cost @ Qty. x1||$176.00 all can contribute to additionalA 2 layer element behaves like a single layer when both layers expand (or contract) together. If an electric field is applied which makes the element thinner, extension along the length and width results. Typically, only motion along one axis is utilized. Extender motion on the order of microns to tens of microns, and force from tens to hundreds of Newtons is typical.
