PVDF is electrically similar to piezo crystal material presently used in a number of respiratory effort belts. The exception being that in Dymedix sensors, it is pressed into a very thin (110 Microns) film giving it a number of distinct advantages, especially when used for airflow detection such as:
• Speed: Extremely responsive allows the ability to see flow limitations better
• Linear: Allows the detection of both apnea and hypopneas from a single sensor
• Stable: Less baseline shift which reduces waveform blocking
These are important features since they all contribute towards more responsive and stable signals resulting in higher quality recordings that are easier to score. In fact, we are so confident these qualities are noticeable we will have a real-time display in the center of our booth (#412) demonstrating live waveforms generated from all our PVDF airflow sensors and effort belts.
