Piezoelectric Respiration (PZT) Sensor

Product Code: 2709-PZT
Piezoelectric Respiration (PZT) Sensor Piezoelectric Respiration (PZT) Sensor Piezoelectric Respiration (PZT) Sensor
Our piezoelectric respiration sensor is an entry-level affordable option for respiratory analysis in a wide range of applications. It has a localized sensing element that measures displacement variations induced by inhaling or exhaling. The elastic strap is provided with the sensor to secure it in place, and can be adjusted in length, enabling the sensor to be applied in different anatomies (e.g. male and/or female) and body locations (e.g. thorax and/or abdomen). Typical applications include monitoring of respiratory rate, respiratory cycle regularity, relative amplitude of the cycle, and others. When multiple sensors are used simultaneously it enables diaphragmatic versus thoracic breathing assessment (e.g. for biofeedback).
