BN-PPGED - BioNomadix PPG and EDA Pair
GSR EDA Analysis

Biopac BN-PPGED / BN-PPGED-T- BioNomadix PPG and EDA

The PPG and EDA BioNomadix amplifier is specifically designed to measure Blood Volume Pulse (BVP) via optical plethysmographic methods and Electrodermal Activity (also known as Electrodermal Response, Skin Conductance Activity/Response or Galvanic Skin Response). These two measurements have been combined into this module pair because they are typically performed on the same part of the body and they are often recorded in parallel for a variety of studies. Record one or both signals.

Biopac BN-PPGED / BN-PPGED-T- BioNomadix PPG and EDA

Biopac BN-PPGED BioNomadix PPG and EDA Wireless Transmitter & Receiver Pair (for use with MP160/MP150 or BioNomadix Logger)

Biopac BN-PPGED-T - BioNomadix PPGand EDA Amplifier/Transmitter module only (BioNomadix Logger use only)

The PPG and EDA BioNomadix amplifier is specifically designed to measure Blood Volume Pulse (BVP) via optical plethysmographic methods and Electrodermal Activity (also known as Electrodermal Response, Skin Conductance Activity/Response or Galvanic Skin Response). These two measurements have been combined into this module pair because they are typically performed on the same part of the body and they are often recorded in parallel for a variety of studies. Record one or both signals.

The transmitter unit can be used either with an MP160/MP150 using a matched receiver unit, or directly with a BioNomadix Logger. The matched pair emulates a "wired" connection from subject to computer, with all the benefits of a fully-wireless recording system.

The PPG (BVP) signal provides for heart rate, inter-beat interval and vasodilation/constriction data. The PPG signal can also be used in conjunction with the ECG signal to generate an estimate of pulse transit time (PTT) and thus, indirectly, real-time blood pressure. The EDA signal provides for indication of eccrine (skin sweating) activity.

The module pair establishes a fixed wideband response of DC to 10 Hz for both the PPG and EDA channels. Additional internal highpass and lowpass optional filters can help provide for high quality amplification of PPG and EDA signals even in the presence of hand/body motion. The system is typically used to measure the PPG and EDA signals as manifested on the fingertips of the left or right hand. However, it can also be used to measure PPG and EDA data on the toes or other body locations.

Raw data is bandlimited from DC to 10Hz, to provide for rapid response PPG and EDA measurement. 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 typically not required.

PPG and EDA data are recorded from two sites, typically the fingertips. Use AcqKnowledge to evaluate the rate of the pulse signal, as generated by the PPG channel. Heart Rate Variability (HRV) can be performed on the PPG signal data. Investigate event-related EDAs and phasic responses using AcqKnowledge's analysis routines. Because BioNomadix devices are fully isolated from one another, comparative EDA measurements are feasible. For example, EDA from one hand can be compared to those of the opposing hand. Attached the transmitter near, or on, the subject's torso via stretchy Velcro strap (included) or try the stretch-mesh, pocketed BioNomadix Shirt. 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.

AcqKnowledge includes a fully automated electrodermal response scoring tool that locates skin conductance responses, visually identifies them in the record and measures them. It also automates event related potentials (ERP) analysis by locating the onset of the stimuli and identifying a valid SCR. See Applications> Psychophysiology for further information.

The BioNomadix PPG/EDA set consists of two parts, a transmitter with strap that is worn by the subject to amplify and send the physiological data, and a receiver module to provide high-quality data. The BioNomadix transmitter uses digital transmission and provides excellent signal quality with a PPG transducer and a short EDA lead set placed close to the signal source. BioNomadix are configured for specific signal types, so you don’t have to adjust settings on the hardware or software for high quality pulse or electrodermal response data.

The transmitter's battery can provide power for up to 72 hours of continuous operation.

The BioNomadix series of wireless, wearable physiology monitoring devices for life science research are available for a wide range of signals, including ECG, EEG, EOG, EMG, EGG, Respiration, Pulse, Temperature, Electrodermal Activity, Impedance Cardiography and Accelerometry. BioNomadix are typically dual-channel units, offering either two of the same signal or a combination of signals.

BioNomadix noninvasively records 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 or BioNomadix Logger. 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 units 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 MP160/MP150 systems or third-party data acquisition hardware via an isolated power supply module (IPS100C). The BioNomadix Logger can pair with up to 3 transmitter units providing up to 6 channels of physiological data as well as a color display for visual feedback, speaker for auditory feedback, vibration for haptic feedback, voice journal for participant comments, event markers, alarms, and a built-in accelerometer.  AcqKnowledge software adds the power of sophisticated automation and scoring routines for each signal type, plus customization options.

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.

BioNomadix Transmitter and Receiver are shipped as a pair with matching serial numbers and include a strap and battery charger. To identify the matched Transmitter-Receiver Pair, press and hold "ID" button on Transmitter and match to Receiver with flashing "Status" LED.
