Yujie Rectangular Piezoelectric Plate Series
Yujie's high-quality rectangular piezoelectric plates (piezo plates) engineered for bending mode applications and linear actuation. Yujie's PZT ceramic strip and bar series offers exceptional dimensional precision with standardized 17 kHz resonant frequency and K31 electromechanical coupling of 0.37 (±6%). These rectangular piezo elements are ideal for bending actuators, energy harvesting devices, vibration sensors, and bimorph transducers requiring elongated geometries.
Features & Applications
Key Applications & Technical Benefits
- •Bending Actuators & Bimorphs: 90mm length enables significant deflection in cantilever and bimorph configurations for positioning and switching applications

Application Engineering
Design support for bimorph cantilever beams, unimorph diaphragms, and stacked multilayer actuators. Deflection calculations, force analysis, and resonance frequency optimization included with custom orders.
Why Rectangular Plates vs. Discs or Rings?
Rectangular piezoelectric plates excel in applications where:
- • Bending motion is required instead of radial expansion (cantilevered actuators, speakers, buzzers)
- • Directional sensing is needed to detect vibration along a specific axis (accelerometers, knock sensors)
- • Space constraints favor elongated shapes in one dimension (slim electronics, wearable devices)
- • Linear arrays must be formed for beam steering or multi-point sensing applications
