We offer two different versions of our respiration sensor for different the applications. This offer often leads to the same question: which sensor is the best for my use case?
Piezo-Electric Respiration (PZT) Sensor
The Piezo-Electric Respiration (PZT) sensor is our affordable, entry-level respiration sensor which consists of a short piezo-electric sensing strip and a non-sensing adjustable and attachable chest belt, which can be adjusted to any thorax or abdominal circumference.
The respiratory signal is acquired by measuring the displacement of the abdomen or thorax during the respiration cycle. Due to the small sensing strip size, this sensor is suitable for respiration monitoring while at rest.
The PZT sensors is ideal as an entry-level sensor for low dynamic conditions (e.g. at rest).
Inductive Respiration (RIP) Sensor
The Inductive Respiration (RIP) sensor is our high-end respiration sensors that is suitable for both respiration monitoring while at rest as well as in dynamic solutions. Other than the PZT sensor, which comes with a short sensing unit and a separate chest belt for fixation purposes, the RIP sensors’ sensing unit is embedded into the entire chest belt itself, providing a greater area for accurately detecting respiratory cycles and being less prone to motion artefacts.
For this reason, it is the recommended option for respiratory monitoring in dynamic solutions or for when you want to have a sensor that is suitable under multiple different acquisition conditions.
The RIP sensor is the suitable choice to cover a variety of different acquisition conditions even in dynamic situations.
Important Information on Apnea Measurements
Both the PZT and RIP sensor measure the displacement of the thorax or abdomen during the respiratory cycles.
During apnea phases (for example when holding your breath) no displacement occurs hence the sensors’ signal return to their original baseline as the apnea phase.
We recommend seeing the following articles for more information about these sensors’ behavior during apnea phases.
