How cool is that? We’ve seen other seismic detectors before, like this piezo-based device, or even one made from toilet parts. We like the simplicity of the capacitive sensor [Alex] used ...

It seems that many seismic sensors are designed to capture big ... a ball of significant mass rests upon three piezoelectric microphone elements spaced at 120 degree intervals.

XY flexure-guided piezo nanopositioning stage delivers ultra-precise motion, long-term stability, and travel to 1,500µm.

The NPS-XY-100A is a piezo scanned flexure guided nanopositioning stage with integrated capacitance position sensors. It is made of Super Invar and is capable of sub-nanometer resolution and ...
