Using AcqKnowledge’s equation generator, a six-lead ECG can be generated from the two recorded ECG leads from the module pair. Use AcqKnowledge software to provide a complete Lead II ECG analysis. The software automatically scores the data and extracts the measurements of interest on a cycle-by-cycle basis. The results are automatically exported to Excel or pasted in the Journal file. AcqKnowledge also includes a fully automated HRV analysis feature. The HRV analysis provides values for VLF, LF, HF, VHF, sympathetic, and vagal, as well as the sympathetic / vagal balance.
Biopotential amplifier/transmitter signal to noise ratio is very high (in excess of 70 dB), as the noise floor of the amplifier/transmission system is only 0.9 µV rms (bandwidth of 0.05 Hz to 150 Hz).
The module set has a fixed gain of 2,000. The largest ECG signal which can be measured is 10 mV P-P, the smallest is less than 1 µV rms.
Interference with other recording modules or systems is greatly minimized because the transmitter is completely battery operated and operates totally independently of any other recording grounds or power sources. The recording transmitter is also extremely safe to use, because there is no physical connection to supply mains.
Due to battery operation of the wireless transmitter and close proximity to the subject’s body, common-mode rejection ratio is extremely high, considerably in excess of any typical wired ECG recording system. Accordingly, notch filters to remove mains interference (50 or 60 Hz) are typically not required.
The transmitter attaches to the subject’s body (torso) via stretchy Velcro strap or stretch-mesh BioNomadix Shirt (see accessories). The exterior transmitter body dimensions (W x H x D) are approximately 6 cm x 4 cm x 2 cm and it weighs approximately 54 grams.
The transmitter’s battery can provide power for up to 72 hours of continuous operation.
BioNomadix noninvasively record high-quality, full-bandwidth data while comfortably allowing subjects to move freely in natural indoor environments. Each BioNomadix device consists of two parts, a transmitter that is worn by the subject to amplify and send the physiological data, and a receiver module. BioNomadix transmitters use digital transmission and short leads or transducers placed close to the signal source to provide excellent signal quality. BioNomadix are configured for specific signal types, so you don’t have to adjust settings on the hardware or software for high quality data.
Multiple BioNomadix can be used to provide the optimum signal combination for a research study requiring biopotential or transducer signals.
BioNomadix accessory items include transducers, electrode leads, and a custom, pocketed stretch-mesh shirt to comfortably hold multiple devices in place. The shirt has zippers placed for easy access to electrode sites and is available from extra small to extra large.
Developed and manufactured by BIOPAC Systems Inc., a leader in life science data acquisition and analysis, the new BioNomadix series delivers all the benefits of a wireless solution with the signal quality & integrity of a wired system. BioNomadix provides a cost-efficient option for uncompromised wireless physiological subject monitoring.
