GENERAL DESCRIPTION
This high-performance inductive respiration
sensor has been specifically designed having
dynamic conditions in mind (e.g. effort trials,
ambulatory sensing, etc.). The sensing
element is embedded in the chest strap
fabric, and spans its full length. Unlike our
affordable piezoelectric (PZT) sensor (which
only measures the displacement in a
localized manner), the RIP option measures
the overall displacement of the thorax or
abdomen, making it more immune to motion-
induced artifacts. The elastic strap is 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).
