The module pair is designed to emulate a “wired” connection from the computer to subject, with all the benefits of a fully-wireless recording system.
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 biophysical transducer signal recording system. Accordingly, notch filters to remove mains interference (50 or 60 Hz) are available but not typically required.
Transducers for skin surface (BN-TEMP-A-XDCR) and fast response temperature (BN-TEMP-B-XDCR) are offered for this system.
Temperature data can be recorded from two independent sites, typically anywhere on the subject’s body or just adjacent to the nostril or mouth to measure inspired/expired airflow. Attach the transmitter unit near or on the subject’s torso via the stretchy Velcro strap included, or try the BioNomadix Shirt (stretch-mesh, pocketed shirt).
Use AcqKnowledge to evaluate the rate of absolute temperature change on one site of the subject’s body or the subtle differences in skin surface temperature between two locations on the body, due to possible blood flow differences. The high signal to noise ratio and high time-based sampling resolution permits the module set to be used for precise temperature research studies. Temperature measurement can also be synchronized to a specific stimulus for stimulus/response investigations, such as those associated with the vasodilation intrinsic to facial blushing or overall body flushing. Using AcqKnowledge, fast or slow response temperature variations data can be isolated to accommodate high quality temperature signal identification.
Interference with other recording modules or systems is greatly minimized because the module 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.
The new BioNomadix series of wireless, wearable physiology monitoring devices for life science research 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 SKT transmitters use digital transmission and 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 skin temp data. Multiple BioNomadix can be used to provide the optimum signal combination for a research study requiring biopotential or transducer signals.
When used with a BIOPAC MP System, up to 16 channels of BioNomadix data can be recorded for multi-subject or multi-parameter protocols. The system also works with multiple MP150 systems or third-party data acquisition hardware via an isolated power supply module (IPS100C). AcqKnowledge software adds the power of sophisticated automation and scoring routines for each signal type, plus customization options.
BioNomadix are available for a wide range of signals, including ECG, EEG, EOG, EMG, EGG, Respiration, Pulse, Temperature, Electrodermal Activity, Impedance Cardiography, Accelerometry, and Gyro. BioNomadix are typically dual-channel units, offering either two of the same signal or a combination of signals.
