smartfor industrial applications

Product Overview
BBPX-MFC is a flexible MFC piezoelectric fiber composite actuator composed of piezoelectric ceramic fibers, flexible interdigitated electrodes and an epoxy resin matrix. It operates in the d₃₃ piezoelectric mode, converting an applied drive voltage into axial strain along the fiber direction. The actuator is designed for smart structures, active vibration control, structural actuation and energy harvesting.

Construction
Component — Function
Piezoelectric ceramic fibers — Generate piezoelectric strain along the fiber direction
Flexible interdigitated electrodes — Create the drive field along the piezoelectric fibers
Epoxy resin matrix — Supports the fibers and forms the flexible composite structure
Lead wires — Connect the actuator to the drive or energy-harvesting circuit

Operating Principle
When voltage is applied to the interdigitated electrodes, the electric field acts along the piezoelectric ceramic fibers. The d₃₃ piezoelectric effect produces axial expansion or contraction. When bonded to a host structure, BBPX-MFC can generate controlled deformation for structural actuation and vibration suppression. Mechanical deformation of the bonded structure can also be converted into an electrical output for energy-harvesting applications.

Typical Applications

• Active Vibration Control — Bonded to machinery, panels and beam structures to apply controlled strain and suppress structural vibration; suitable for precision equipment, smart structures and active damping systems.
• Aircraft Wing and Aerospace Structure Control — Conforms to wing surfaces and other curved components for structural deformation control, vibration suppression and smart-structure development.
• Cantilever Beam Actuation — Supports bending control, vibration testing, modal control and laboratory research platforms when bonded to cantilever beams.
• Piezoelectric Energy Harvesting — Converts mechanical strain from structural vibration or bending into electrical energy for low-power systems.

Installation Guidelines

• Keep the bonding surface flat, clean and dry.
• Ensure full contact between the actuator and host structure for effective strain transfer.
• Avoid folding, sharp bending or damage to the electrodes and lead wires during installation.
• Match the drive circuit to the actuator capacitance, target strain and operating conditions.
