Piezoelectric Extending Transducer (D220-H4BR-2513XE) Meta||Unit Cost @ Qty. x1||$176.00 It has high motion per

It has high motion per volt sensitivity but its upper temperature range is limited and its properties are more sensitive to temperature

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

When an electric field having the same polarity and orientation as the original polarization field is placed across the thickness of a single layer disk

the piece expands along the axis of polarization (thickness direction) and contracts perpendicular to the axis of polarization (radial direction)

Because they have no center shim reinforcement

Piezoelectric Extending Transducer (D220-H4BR-2513XE) Meta||Unit Cost @ Qty. x1||$176.00 It has high motion perA 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.
