The ErgoPLUX Package
Our ErgoPLUX generic kit contains:
1 bioPLUX wireless system for biosignals acquisition;
5 sensors for surface electromyography, 1 ground electrode and detection surfaces;
1 accelerometer for vibrations measurement.
BioPLUX wireless system
The bioPLUX is the device that collects and digitizes the signals from the sensors and transmits via Bluetooth to the computer, where they are visualized in real time.
Technical information
Bluetooth® Connectivity - 10m range, with standard adapter; >100m with high range adapter;
8 Analog Channels (12 bit) - Sampling rate of 1000 Hz;
1 Digital I/O Port (1 bit) - Input/Output adapter included;
86g;
Compact dimensions – 84x53x18mm.
emgPLUX sensor
The emgPLUX sensors are designed to capture surface electromyography (sEMG) signals from the skin surface.
After the correct placement of the sensor on the muscle that you want to monitor, the signals are captured and transmitted by the bioPLUX device to the computer, where the software processes and translates them into information of the muscular load demanded, displaying it in real time on-screen.
Detection Surfaces
The electromyography sensors provided are bipolar and with variable distance between electrodes, allowing users to apply them in the most convenient muscles for the collection of signals. It is advised that the application of electrodes on the skin should be with a distance of 2 cm between them, with a parallel orientation to the muscle fibers.
Reference Electrode
For the monitoring of the muscle activity it is necessary to use at all times, a reference electrode with the emgPLUX sensor. This electrode collects the basic electrical signal always present at skin surface and that is not a result of muscle activity (noise). This signal is the reference to measure the signal and the electromyography sensor must be placed on a location with reduced muscle activity. Thus, the electromyography signal captured and processed represents only the signal generated by the activity of the muscle where the bipolar sensor was placed.
Accelerometry Signal
The xyzPLUX triaxial accelerometer is designed to measure acceleration from the three axes.
Our triaxial accelerometer is robust, stable, accurate, with a dynamic range of ± 3g and due to it's small size, it's integration is very easy.
It has been developed for applications where cinematic and motion measurements are required.
This sensor has a high level of sensibility and therefore, for the purpose of measure vibrations, it is advised to use it fixed in a way to minimize the undesirable artifact movements of the sensor.
Band strap
We provide a band strap with the ergoPLUX system to fix the accelerometer and measure the vibrations in a known location.
To measure vibrations in the hand-arm system, the accelerometer should be on the hand, in contact with the vibrating tool. To measure vibrations that affect the whole body and when the person is working in a standing position, the band strap should be attached to the shoe (do not step the device), and when working in a sitting position the band strap should be positioned in the chair with the worker sited above it.
Other sensors
PLUX offers a variety of sensors which could be used for different types of ergonomics assessment not contemplated in the generic kit.
anglePLUX
Our single plane high precision goniometer are specially designed for angle measurement in biomechanics applications.
forcePLUX
Our resistive force sensor is particularly suitable for integration in clothing or footwear. Some of the applications of this sensor include postural analysis, relative strength measurement and walking patterns evaluation.
edaPLUX
Our electrodermal activity sensor is able to detect even the most feeble galvanic skin response events. Some of the applications of this sensor include detection of changes in the attentive, cognitive and emotional states.
