Shape Memory Alloy (SMA) Actuators for Your smart vacuum gripper
Shape Memory Alloys (SMA) are smart materials that contract when an electric current flows through the wire and return to their original form when released. This enables direct, compact, and high-density actuation, offering an innovative replacement for traditional electromagnets and motors.
Key Features
Highest energy density of any known actuator principle
Example: 1 g of NiTi wire lifts a 10,000 g mass by 20 mm when electrically powered.
Built-in sensing capabilities
Electrical resistance changes correlate directly with contraction. This allows precise control without external sensors → extremely compact system design.
Silent operation
No gears, no vibrations – SMA actuators work almost noiselessly.nts
Versatile and highly customizable in size, shape, physical properties, electronics, and system integrations
We integrate a vacuum sensor into our vacuum grippers to reliably monitor and verify all functions.
Robust high-tech material
Biocompatible, corrosion-resistant, and durable – suitable for demanding environments.
Tested over millions of cycles
xtremely lightweight: the drive itself weighs around 1 g. The complete system, including housing, electronics, and sensor, weighs less than 100 g.
