  • Piezoelectrical Gripper
Feb 2006
piezosystem jena GmbHRequest Info
JENA, Germany, Feb. 9 -- Piezosystem Jena has developed a gripper system for the smallest components in micro- and nanotechnology. The gripper, based on a miniaturized piezo actuator, has solid-state flexure hinges and a 300-µm range of motion. Combined with adaptable tools, this system can be enlarged accordingly. A piezoelectrical actuator with sub-nm resolution ensures a precise aperture angle in the direction of motion. The actuator is closed by the elastic resilience of a spring. The gripper force can be adjusted precisely, and the outside design of the gripper can be easily configured. A simple analog voltage signal in the range of 0 to 150 V is required. The technical requirements for an optimal system integration are relatively low. Also, the tool collet on the moving part of the gripper can be custom-designed, making it suitable for OEM applications.

The use of atoms, molecules and molecular-scale structures to enhance existing technology and develop new materials and devices. The goal of this technology is to manipulate atomic and molecular particles to create devices that are thousands of times smaller and faster than those of the current microtechnologies.
