High-performance linear piezoelectric platform is the core equipment for micro-nano manipulation and ultra-precision manufacturing. A novel resonant linear piezoelectric platform (RLPP) with ...

Archimedes screw turbines and generators have emerged as robust, low-head hydropower solutions that exploit the kinetic energy of low-volume water flows. By reversing the traditional Archimedes ...

This paper proposes a motion de-amplification-based actuator design, which comprises coarse and fine-stages that respectively achieve macro and micro-scale linear actuation. The proposed ...

For tasks requiring sub-micrometer precision – such as alignment, adjustment, or fine positioning – PI’s M-235, L-220, and M-230 series linear actuators offer reliable, high-performance motion. The ...
