The BioNomadix BN-RSPEC module combines respiratory effort (RSP) measurement and electrocardiogram (ECG) recording in a single wireless transmitter.

BioNomadix · Cardiology and respiration

The BioNomadix BN-RSPEC module combines respiratory effort (RSP) measurement and electrocardiogram (ECG) recording in a single wireless transmitter.

A hybrid cardio-respiratory channel for heart rate variability analysis that accounts for respiratory phase (RSA), with no cable constraints for the subject.

BioNomadix RSP+ECG is an expansion module, not a standalone system

The BioNomadix transmitter and receiver alone do not record or store data. Measurement requires an MP200 data acquisition unit (or the older MP160/MP150) together with AcqKnowledge software.

The BioNomadix RSP+ECG receiver plugs into an MP200 channel input, and the recorded signal joins a common, synchronized timeline alongside other modules — both wired and wireless.

Key features

2-in-1: RSP + ECG

One transmitter, two independent physiological channels — respiration and the heart's electrical activity — recorded simultaneously.

Full freedom of movement

Wireless transmission between the transmitter and receiver — the subject is not restricted by cables during recording.

Compact transmitter

Worn with a strap or in a dedicated pocket of the BioNomadix BioShirt, together with snap-in textile electrodes.

50/60 Hz notch filter

Optional mains interference reduction on both channels, without loss of signal quality.

Where to place the sensors

Click the points on the silhouette to see the typical placement of the respiration belt, ECG electrodes, and ground.

Respiration belt: location confirmed in BIOPAC materials (Respiration Transducer). ECG electrodes: standard BIOPAC lead II configuration, adapted to the torso — for illustration purposes. A ground (GND) electrode is required in every ECG connection; its exact position on the torso is approximate.

Lead II only

The BN-RSPEC measures a single limb lead: II (LL−RA). This is not the full Einthoven triangle — the LA electrode is missing, so leads I and III are not available.

GND is a reference electrode that reduces interference — it is not part of the differential measurement itself.

How it works

Transmitter on the subject

Simultaneous measurement of respiratory effort (RSP belt) and ECG (electrodes) in a single module.

Receiver + acquisition system

Wireless transmission at 2000 Hz to the MP200, MP160, or MP150.

Analysis in AcqKnowledge

HRV corrected for respiratory phase (RSA), respiration rate, and heart rate in real time.

Experimental applications

Simultaneous, wireless measurement of respiration and ECG in a single module is used in cardio-respiratory research and anywhere correlating autonomic nervous system responses with respiratory phase matters.

RSA — respiratory sinus arrhythmia

Analysis of Respiratory Sinus Arrhythmia: the modulation of heart rate by the respiratory cycle, requiring simultaneous, synchronized recording of both signals.

Cognitive load

Assessment of cognitive load in ergonomics and UX research based on the combined dynamics of respiration and heart rate.

Neuromarketing and HCI

Affective responses to stimuli in human-computer interaction, recorded without cable constraints for the subject.

Simulator research

Mobile psychophysiological research in simulators, where the subject's freedom of movement is a condition for a realistic task.
