BioNomadix 2Ch Wireless Heel-Toe Strike Transmitter+Receiver

Name: BioNomadix 2Ch Wireless Heel-Toe Strike Transmitter+Receiver
Brand: BIOPAC
SKU: 18156

Transducer for wireless recording of heel and toe strike activity, includes a Heel/Toe Strike sensor and an adapter for communicating with the wireless transmitter, which can be conveniently strapped to the ankle.

Key Parameters

Research Applications

Biomechanics, Neuromarketing, Gait analysis

Transmission Parameters (2000 Hz)

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

Wearable Architecture

The module emulates a classic “wired” connection to the computer, while providing the full benefits of a Wearable system:

Body-worn mounting: The transmitter can be easily attached to the patient’s wrist using the included flexible Velcro strap, or 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 patient), the common-mode rejection ratio is extremely high. Notch Filters are usually not required at all!

Safety: No physical contact between the patient’s equipment and the fixed power installation minimizes any risk of electric shock.

Architecture and Compatibility

BioNomadix Strike Transmitter, MP Series

Signal Flow (Data Flow)

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

Wearable Transmitter

Worn on the subject's body. It records the physiological signal directly from the body at 2000 Hz, instantly digitizing it on-chip and sending radio packets.

Receiver Module

Receives encrypted telemetry and decompresses the signal in real time. This module physically plugs into a slot 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 over a wired Ethernet connection to the powerful AcqKnowledge software on the researcher's computer.

Experimental Application

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

Key Areas

Biomechanics, Neuromarketing, Gait analysis

Group Dynamics

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

Movement and VR Research

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

Additional Applications

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 for stimuli.

Access to Raw Data

Full access to 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 for users trying to explore virtual surroundings. Now the quality of the collected physiological data is perfectly smooth, and participants barely remember they are wearing the equipment.

Frequently Asked Questions (FAQ)

Does the system require a wired connection to the patient?

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

What analysis software is included?

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

Can I synchronize the system with an Eye-Tracker?

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