Features & Applications
Key Applications & Technical Benefits
- •Bending Actuators & Bimorphs: 90mm length enables significant deflection in cantilever and bimorph configurations for positioning and switching applications
- •Energy Harvesting Systems: Elongated rectangular geometry optimized for capturing vibration energy in 17 kHz range with capacitance 81-98pF
- •Vibration Sensors & Accelerometers: Thin profile (0.35-0.39mm) provides high sensitivity to bending stress and acceleration forces
- •Linear Ultrasonic Motors: Rectangular shape ideal for stator elements in linear USM designs requiring directional motion
- •Acoustic Beam Forming: Multiple rectangular elements can be arrayed to create directional ultrasonic beams for sensing and communication
Ask for volume pricing on larger orders or annual requirements. Samples, custom designs and development enquiries are welcome too.

Precision Cutting & Grinding
Advanced dicing saws and surface grinding equipment maintain dimensional tolerance of ±0.05mm on length/width and ±0.01mm on thickness. Edge quality optimized to minimize stress concentration and prevent chipping during handling and assembly.
Bimorph & Multilayer Construction
We offer complete bimorph assembly services including piezo plate bonding to metal shims (brass, stainless steel) with epoxy or polyimide adhesives. Series and parallel wiring configurations available for optimized voltage/displacement characteristics.
Custom Electrode Patterns
Standard full-area electrodes or custom segmented patterns for independent control of multiple actuator zones. Electrode extension pads positioned for easy wire bonding or conductive adhesive attachment.
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
