Name: BioNomadix 2Ch Wireless Goniometry Transmitter+Receiver
Brand: BIOPAC
SKU: 18157

The BioNomadix 110 mm Goniometer is a wireless, twin-axis sensor that measures angles in two planes of movement. It allows simultaneous measurement of flexion/extension and radial/ulnar deviation.

Key Parameters

The BioNomadix 110 mm Goniometer is a wireless, twin-axis sensor that measures angles in two planes of movement. It allows simultaneous measurement of flexion/extension and radial/ulnar deviation.

Research Applications

Joint motion measurement, Biomechanics, Health and rehabilitation

Transmission Parameters (2000 Hz)

Telemetry data is transmitted at a rate of 2000 Hz, providing ultra-high waveform resolution at the receiver. The system features internal, optional Highpass and Lowpass filters that compensate for potential hand-movement artifacts.

Wearable Architecture

The module simulates a classic “wired” connection to the computer while delivering the full advantages of a wearable system:

Body-worn mounting: The transmitter can be easily fastened to the subject’s wrist using the included flexible Velcro strap, or worn in the dedicated BioNomadix Shirt.

Noise immunity (CMRR): Because the device is battery-powered and isolated from the mains (no 50/60 Hz power cables on the subject), the common-mode rejection ratio is extremely high. Notch Filters are typically not required at all!

Safety: The absence of physical contact between the subject’s equipment and the stationary power installation minimizes any risk of electric shock.

Architecture and Compatibility

Compatible with the BioNomadix system, the BN-GONIO goniometry amplifier, and other BIOPAC systems.

Signal Flow (Data Flow)

The BIOPAC telemetry system consists of 3 real-time connected modules that ensure crystal-clear signal integrity from the subject all the way to the finished chart on screen.

Wearable Transmitter

Worn on the subject's body. Records the physiological signal directly from the body at a rate of 2000 Hz, instantly digitizing it on the microchip and sending radio packets.

Receiver Module

Receives the encrypted telemetry and decompresses the signal in real time. This module plugs physically into a socket on the universal MP160 or MP200 research station.

Main Unit (MP200) & Software

The main station synchronizes signals from other interfaces (e.g. Eye-Tracker) and reliably transmits them via cable over the Ethernet protocol to the powerful AcqKnowledge software on the researcher's computer.

Technical Specification

Key technical parameters of the transmitter and receiver for both recorded physiological channels.

Experimental Application

Physiological measurements are the gold standard in research, widely used in advanced scientific applications.

Key Areas

Joint motion measurement, Biomechanics, Health and rehabilitation

Group Dynamics

Because the system pairs separate wireless modules, you can freely monitor the reactions of two or more subjects side by side (e.g. during cooperative games or social experiments), without worrying about tangled cables.

Research in Motion and VR

Not being tethered to a lab "desk" opens the way for free navigation through VR simulators, testing interfaces while walking, or tracking stress under realistic conditions (Ecological Validity).

Additional Applications

The BioNomadix 110 mm Goniometer is a wireless, twin-axis sensor that measures angles in two planes of movement. It allows simultaneous measurement of flexion/extension and radial/ulnar deviation.

Laboratory-Precision Parameters

Acquisition Quality

24-bit signal resolution with dynamic range. Extremely low noise floor and built-in hardware filters that minimize motion artifacts.

Synchronization (Triggering)

Full compatibility with the LSL (Lab Streaming Layer) protocol, TTL ports, and E-Prime. Guarantees microsecond-level timing precision of stimuli.

Access to Raw Data

Full insight into uncompressed Raw Data signals. Direct export to research formats CSV, MATLAB, and Python API integration.

Scientific Recognition

Peer-reviewed equipment, widely cited in thousands of global publications in psychophysiology and neuroscience.

Trusted by leading researchers from institutions such as:

Harvard University STANFORD MAX PLANCK INSTITUTE Oxford

The BioNomadix system has drastically simplified our research in Virtual Reality environments. Previously, cables caused constant artifacts in users trying to explore the virtual environment. Now the quality of the collected physiological data is perfectly smooth, and participants don't even remember they're wearing the equipment.

Frequently Asked Questions (FAQ)

Does the system require a stationary connection to the subject?

No, the BioNomadix module is fully wireless and worn on the subject's body. It communicates with the receiver via dedicated high-frequency telemetry, allowing full freedom of movement in the lab or within VR simulator spaces.

What analysis software is included?

Signals from the amplifier are routed directly to the AcqKnowledge research software, which offers automatic detection and analysis routines for changes in the measured physiological parameters, both in real time and during post-processing.

Can I synchronize the system with an Eye-Tracker scanner?

Yes. By using the open Lab Streaming Layer (LSL) protocol or the digital Hardware Triggering inputs in MP160 systems, all sensor streams can be perfectly time-aligned with video from eye-trackers or fNIRS.
