Sensor Influence on the Precision of Piezo Positioning Stages

The choice of feedback sensor is one of the key performance factors of a piezo positioning stage. Below is a comparison between the two most commonly used sensors. When the absolute positioning information plays a critical role in scientific results, researchers prefer capacitive sensors. When cost is most important and / or results are based […]

Reliable Piezo Motion Devices for Industrial and Space Applications

Piezo ceramics convert electrical energy directly into mechanical motion and vice versa, based on crystalline solid state effects. Piezo actuators are quite unique in combining force, speed and precise motion into a small package. To make them more accessible for OEM designers, manufacturers can package the actuators inside an arrangement of flexures providing precision guidance, […]
