BioHarness Data Logger in Action

BioHarness with AcqKnowledge software is a state-of-the-art lightweight portable biological data logger and telemetry system. It monitors, analyzes and records a variety of physiological parameters including ECG, respiration, temperature, posture, and acceleration. The BioHarness operates in Bluetooth transmitting mode for live viewing of data or data logging mode. In the data logging mode, the BioHarness logs the data for later download to the AcqKnowledge software using the USB docking and charging cradle that comes with the system.

BioNomadix Wireless EMG for Neuro-controlled Prosthestic

A wireless neuro-actuator prosthetic was created using BIOPAC’s wireless hardware and additional custom hardware. The electromyogram of both opponens pollicis (thumb flex) and pronator quadratus (wrist rotate) was recorded from the Subject’s palms and wrists, and the real-time, high-resolution EMG signal was processed to control the grip and rotation of remote handgrips. For each arm, a BioNomadix Wireless EMG transmitter/receiver set was used with short 15 cm leads (BN-EL15-LEAD2 and BN-EL15-LEAD3) and five disposable electrodes EL503). EMG data was sampled at 2000 Hz and wirelessly transmitted at 2.4 GHz via bidirectional digital communications. The EMG signal output was switched to alternate mode for Integrated RMS (Envelope Detection Mode) and further conditioned to drive gripper and wrist servo motors. BioNomadix Wireless Physiology.

BIOPAC NIBP-MRI: How to Apply Sensor to Brachial Artery

The NIBP-MRI is a wireless and noninvasive physiological monitoring system that tracks blood pressure, using Pulse-Decomposition Analysis (PDA) technology, as well as heart rate.

NIBP-MRI operates passively at a low constant coupling pressure of 40 mmHg. After being provided a calibrated blood pressure reading, the device tracks blood pressure by analyzing the timing and amplitudes of the primary left ventricular ejection pulse as well as the arterial pulse reflections, at the thumb, at the middle phalange of the middle finger, at the wrist, or upper arm. The system provides relative, real-time, beat-to-beat pressure measurement values during magnetic resonance imaging. Learn about BIOPAC MRI Solutions.

CAM-HFR-A High Frame Rate Camera System

With the CAM-HFR-A system from BIOPAC you can record high-frame rate video (at up to 100 fps) tightly synchronized with physiological data from your existing MP160/MP150 Research System. The system connects to a Windows PC via included Ethernet card and is controlled through the Media Menu in AcqKnowledge 4.3.1 or above. CAM-HFR-A.

EL-CHECK Electrode Impedance Checker

Use EL-CHECK to determine electrode/surface contact impedances and correct noise/impedance issues before you begin recording to improve the signal quality of your data. EL-CHECK is suitable for measuring electrode contact impedance for all surface biopotential measurements, including ECG, EEG, EGG, EMG, EOG, Bioimpedance and Impedance Cardiography. The EL-CHECK permits simultaneous connection of up to three electrode leads, for quick impedance checking between any two electrodes in the three connected leads (Active or Vin+) and (Reference or Vin-) and GND.
Measurements are selectable to a standard three-point contact (Vin+ to GND, Vin- to GND and Vin+ to Vin-). Electrode impedance range from less than 5 Kohm to greater than 50 Kohm is indicated in seven levels. EL-CHECK accepts standard Touchproof and BioNomadix connectors. EL-CHECK will support over 50,000 10-second measurements with a single 9-volt battery. EL-CHECK

Epoch wireless in vivo recording

Epoch wireless in vivo recording systems are a low-cost solution for continuous, long-term biopotential recordings from rodents…EEG (2, 4, or 6 channel), ECoG, ECG, EMG. Epoch wireless transmitters are available for a variety of signals with 2 week, 2 month or 6 month battery life, with new reusable and differential transmitter options. This overview details the components of epoch wireless in vivo recording systems. When paired with BIOPAC’s MP Research System & AcqKnowledge, automation and scoring tools can identify seizures, predefine and control recording protocols, set triggers based on external events, quickly score multiple channels of EEG data simultaneously, derive frequency bands, complete a frequency analysis, look at Alpha RMS, and more.

This video describes the technology behind Epoch transmitters and demonstrates the use of  this novel miniature telemetry system, specifically engineered for use in immature rats or mice, which is also effective for use in adult animals in pre-clinical research with continuous EEG in young animal models of seizures and other neurological disorders.

Eye Tracking & Physiology – Synchronized Data

A demonstration of AcqKnowledge software multimedia functionality when used in conjunction with the SMI Eye Tracking Glasses and Wireless BioNomadix Logger & Physiology data transmitters.

Left side shows data downloaded from the BioNomadix  Logger for transmitters placed on subject: on-board accelerometer (x, y, z); Heart (ECG); Pulse; Respiration; Electrodermal activity.

Right side shows video recorded from SMI Eye Tracking glasses as the subject was wearing them and performing tasks while fully mobile.

Playback Shows video of precisely what the subject is looking at as performing a task and you see the cursor move forward in the data file, synchronized to the precise point in the video.

Green dot shows focus point of subject (driver in this case), so at any given moment in time you know precisely were driver is looking.

Full control over Video and physiological  data , jump thru video to finds an area of particular interest in , driver distracted by the on-board display as car is coming up to traffic lights and a lot is going on there, plus we can also skip to a region of physiological data and jump to the precise point in the video.

Significant noise from the accelerometer, from undulations in the road (vibration) and we can see the road change from black asphalt to cobbled street that provided more vibration. See the car hit the cobbled street and vibrations show on the accelerometer data channels.

User has complete control: physiology file advances video or video moves to precise point in the physiological record…or just play the entire recording.

Vibromyography Solutions from BIOPAC (English)

VMG transducers record vibration data received from microelectromechanical systems (MEMS) sensors and proprietary software. Of greatest importance is that the muscle efforts reported by the sensor are not simply relative measures, but represent absolute muscle effort. Comparisons can be made between measurements on a given muscle from day to day, and comparisons can be made between measurements made on different muscles on a person during a functional activity.
