GENERAL DESCRIPTION
Our piezoelectric respiration sensor is an
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).
