A research team led by Dr. Lim Sang-kyu in DGIST's Department of Energy and Environmental Technology has developed a smart ...

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.
