Wireless Bed Sensor

When our blood circulates and our heart beats, the moving blood causes a tiny recoil in a longitudinal direction, this recoil couples to the bed causing periodic vibrations. Murata’s ultra-low noise accelerometers and sophisticated proprietary signal processors, detect these subtle vibrations and provide data for bio-signals like heart and respiration rate.
