3.1.7 Respiration (PZT)
Figure 31: 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).
How to use this sensor
This respiration sensor is a piezoelectric sensor and the membrane is centered on the
flexible strip from where the cable comes out. As it measures respiration by means of the
bending of the strip, the more the center of the strip is over the chest contour the better.
Also, make sure the sensor fastened firmly to the chest to increase the signal quality and
reliability. Signal quality will increase if the sensor it too loose.
How to connect your sensor to your biosignalsplux
The respiration sensor can be connected to any of the available analog inputs of your
biosignalsplux device (see 2.3.2 Analog Inputs).
This sensor does not require an additional reference electrode.
How to configure your sensor in OpenSignals (r)evolution
Open the OpenSignals (r)evolution device manager and select the device you have your
respiration sensor connected to. Select the channel of your respiration sensor and select
RESP from the dropdown menu (click on the arrow in the channel’s field that appears
when you hover over the channel’s field).
