The Piezo Vibration Sensor from TAIYO YUDEN is based on piezoelectric element technologies developed over many years. The sensor features high sensitivity at low frequencies, low power consumption, and a compact size. With support for frequencies from 0.1 Hz to 100 Hz, the sensor provides a higher level of detection sensitivity than competing solutions; and excels in detecting the vital signs of humans and animals as well as low-frequency mechanical vibrations.

Introductory Video

The following video provides a simple explanation of the Piezo Vibration Sensor from TAIYO YUDEN.

Positioning of the Piezo Vibration Sensor

The TAIYO YUDEN sensor not only detects the pulse and heartbeat profile with its high sensitivity in the low frequency band, but it is also able to accurately detect the breath profile as well.
