Bimorph Actuators for Controlled Bending and Deflection
Piezoceramic bimorphs convert electrical signals into controlled bending motion, enabling comparatively large deflections in compact designs. With decades of experience in piezoceramic technology, CeramTec develops customized bimorph solutions for applications requiring precise movement, reliable performance and application-specific design.
Different configurations and reinforcement options allow the actuator characteristics to be tailored to the required displacement, force, installation space and operating conditions.
Series and parallel bimorphs combine high sensitivity with cost-effective performance. Their controlled bending behavior makes them suitable for applications requiring precise deflection, sensing or dynamic response. Typical applications include:
- Sensor and measurement systems
- Positioning transducers
- Ultrasonic transducers
- Printing technologies
- Viscosity measurement systems
- Flow measurement systems
Carbon-Fibre and Metal-Reinforced Bimorphs
Reinforced bimorph designs combine a high force-to-deflection ratio with excellent durability. Carbon-fibre or metal reinforcement provides additional mechanical robustness for applications requiring reliable actuation and long service life. Typical applications include:
- Pneumatic valves for industrial and automotive applications
- Valves for medical applications
- Insulin pumps
- Tactile displays and Braille applications
- Textile machinery
- Optical switches
- Energy harvesting
From Piezoceramic Element to Customized Solution
Selecting the right bimorph design depends on the required displacement and force, available installation space, operating voltage, frequency, mechanical load and environmental conditions.
CeramTec combines piezoceramic material expertise with application-specific design and co-development to provide bimorph elements tailored to the technical requirements of the final system.
