DEVELOPMENT OF FOLDED PENDULUM AS ONE-DIMENSIONAL VIBRATION SENSOR BASED ON GIANT MAGNETORESISTANCE (GMR)

Earthquakes that occur due to small-scale ground movements (M>2) have frequency 0.1-10 Hz range.The instruments that can be used to measure is a seismometer. In general, seismometers use the pendulum concept, including the folded pendulum. The folded pendulum is constructed from two simple pendul...
