Piezoelectric Extending Transducer (T220-H4BR-2513YE) Meta||Sensor Resonant Frequency (Hz)||430 A 2-layer piezoelectric actuator produces

A 2-layer piezoelectric actuator produces curvature when one piezo layer expands while the other layer contracts

Because they have no center shim reinforcement

PSI-5H4E is an industry type 5H (Navy Type VI) piezoceramic

Thin vacuum sputtered nickel electrodes produce extremely low current leakage and low magnetic permeability

A 2-layer element behaves like a single layer when both layers expand (or contract) together

Piezoelectric Extending Transducer (T220-H4BR-2513YE) Meta||Sensor Resonant Frequency (Hz)||430 A 2-layer piezoelectric actuator producesA 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.
