The Respiratory Belt Transducer contains a piezo-electric device that responds linearly to changes in length. It measures changes in thoracic or abdominal circumference during respiration. These measurements can indicate inhalation, expiration and breathing strength and can be used to derive breathing rate. The transducer may be used to characterize breathing patterns. The transducer is a solid-state device that requires no excitation. The MLT1132 connects directly to a BNC Input on any PowerLab or MacLab. It is comfortable to wear, rugged, reliable and washable. It is suitable for use on animals of various sizes (from cats to horses) as well as humans.
For researchers wanting a MR Compatible device the MLT1133
Piezo Respiratory Belt Transducer (MR) is available.
