Frequently Asked Questions (FAQs)

Do I need any hardware of software programming skills to record and visualize sensor data?

No, our easy-to-use and free OpenSignals (r)evolution software enables full control of the device in online & offline data acquisition & visualization.


Where can I find detailed instructions & technical information for my biosignalsplux kits and sensors?

You can find user manuals, datasheets, technical notes, and other documentation in our biosignalsplux documentation page.

Please note that the documentation undergoes regular updates as the list of biosignalsplux features continues to grow, reason for which we do mainly provide digital documents for your products. Please consider the environment before printing biosignalsplux products.


I am having Bluetooth issues. What can I do?

Bluetooth issues may occur when using onboard Bluetooth modules of your computer. This is often due to incompatibilities between the biosignalsplux device and the Bluetooth module and its driver. For this reason, we strongly recommend using the biosignalsplux USB Dongle which comes with your biosignalsplux kit.

You can find detailed instructions on how to set up and use the Bluetooth Dongle in our forum.


Is biosignalsplux a medical device?

No, biosignalsplux and any of its sub-products are not a medical devices. All biosignalsplux products are intended for use in life science education and research applications; they are not medical devices nor are they intended for medical diagnosis, cure, mitigation, treatment or prevention of disease. Please visit our Regulatory page for more detailed information.


Can I develop medical devices based on biosignalsplux?

Yes, we do provide possibilities to support your medical device development using biosignalsplux. Please contact us directly via e-mail at support@plux.info to discuss your project in detail and visit our R&D Services for more information.

I need to get in contact with you. What is the best way contact you?

You can reach us via telephone (+351 211 956 542) or via the following:

Does the biosignalsplux hub conduct any signal filtering or conditioning?

The analog front-end of each biosignalsplux sensor conducts minimal signal conditioning in order to narrow down the spectrum of acquirable signals according to sensor and signal-specific characteristics (e.g. frequency bandwidths, gain). You can find more information about the analog front-end characteristics in each sensor's datasheet.

However, the pre-conditioned analog signal provided from the sensor is not further processed but provided in the raw format.


What are the sampling rate options for biosignalsplux devices?

Using our OpenSignals (r)evolution software you can select sampling rates of 10Hz, 20Hz, 50Hz, 100Hz to 1kHz (in 100Hz steps), or 1kHz to 3kHz (in 1kHz steps) for simultaneous use of up to 8 sensors per biosignalsplux hub. Using the biosignalsplux APIs, you can set the sampling rate to any integer value between 10Hz and 8kHz, although some additional limitations (e.g. limited number of channels) can occur at the higher end of the sampling rate spectrum.


What are the sampling resolution options for biosignalsplux devices?

biosignalsplux hubs support sampling resolutions of 8-bit and 16-bit, although 12-bit can also be found in older versions. Please note that the FNIRS & and wearable solutions can be found to have other pre-set sampling resolutions.


How many devices can I connect and use simultaneously in synchronized acquisitions?

Synchronized acquisitions allow you to connect up to 3 8-channel biosignalsplux devices to acquire sensor data from up to 24 channels simultaneously. Please note that additional accessories may be necessary for such acquisitions in case those are not already included in your biosignalsplux kit.


Can I use any biosignalsplux sensor with my biosignalsplux hub?

Yes, all of our sensors work with our 4-channel & 8-channel hubs. However, please note that the use of our SpO2 (Versatile), SpO2 (Finger Clip), or FNIRS sensors is currently limited to only 1 per device as those are the only digital sensors of the biosignalsplux sensor portfolio. Multiple sensors of any other biosignalsplux sensor type can be used without any further limitations (e.g. 8x EMG per 8-channel hub).


My computer already has onboard Bluetooth. Do I need to use the Bluetooth dongle that comes with my kit?

If you are using a Windows operating system, then yes, we do strongly recommend using the Bluetooth dongle that comes with your biosignalsplux kit. The use of the Bluetooth dongle

Bluetooth issues may occur when using onboard Bluetooth modules of your computer. This is often due to incompatibilities between the biosignalsplux device and the Bluetooth module and its driver. For this reason, we strongly recommend using the biosignalsplux USB Dongle which comes with your biosignalsplux kit.

You can find detailed instructions on how to set up and use the Bluetooth Dongle in our forum.

Is the OpenSignals software included in the biosignalsplux kits?

Yes, our OpenSignals software is included in all biosignalsplux kits and can be downloaded for free from our software page for Windows, macOS, and Linux operating systems. You can also download our OpenSignals Mobile app for Android devices free of charge from the Google Play Store.


What are the main features of the free OpenSignals software?

Our OpenSignals software supports real-time data acquisition and visualization from all BITalino and biosignalsplux devices. The acquired data can be visualized after the acquisition and exported in the .TXT, .H5, and .EDF file formats to compatible third-party software.

In addition, OpenSignals comes with built-in streaming features which allows you to stream the acquired data to third-party software using the open-source Lab Streaming Layer (LSL) and TCP/IP protocols.


Are the OpenSignals software add-ons included in the biosignalsplux kits?

We offers two types of OpenSignals add-ons: free add-ons (e.g. signal statistics) and paid add-ons. The free add-ons already come pre-installed with the OpenSignals software and are free to use. The paid add-ons are not included in the OpenSignals software by default, but may be included in your biosignalsplux kit.

Can I integrate the biosignalsplux hardware into my software?

Yes, that is possible. We offer two options to do so: using our Application Programming Interfaces (APIs) or using the Lab Streaming Layer (LSL) and TCP/IP streaming features of our OpenSignals software.

How can I order biosignalsplux products?

You can request sales support, quotation, and place orders using the following ways:
