The biosignalsplux piezoelectric Respiration (PZT) sensor is an entry-level and affordable solution for basic respiration data acquisition. This sensor consists of a wearable chest-belt with an integrated localized sensing element that measures displacement variations caused by the volume changes of the thorax or abdomen during respiratory cycles (inhaling/exhaling).
The elastic chest-belt can be adjusted in length to be applicable on different anatomies (e.g. male and/or female), body locations (e.g. thorax and/or abdomen), and thorax/abdomen circumferences. Typical applications of this sensor include respiration monitoring to determine respiration cycles, rates, relative amplitudes, and other features.

This sensor is not a standalone use sensor and requires the use of a biosignalsplux hub and electrodes in order to acquire any data. It can be included in the following biosignalsplux kits which come with all the needed hardware and accessories for PZT data acquisition:
The Respiration Analysis add-on for the OpenSignals (r)evolution software is the ideal software extension for the biosignalsplux Piezo-Electric Respiration (PZT) and Inductive Respiration (RIP) sensors. It is designed to extract temporal and spectral parameters to provide useful information about the breathing dynamics, such as respiratory rate, amplitude parameters, and basic spectral analysis.
