Versatile Bio is a mobile and versatile real-time biosignal amplifier, optimised for out-of-the-lab applications that require great freedom of movement for the user, and exceptional signal quality for the researcher. With a simple placement on the arm or waist, it can reliably record 21 channels (extensible to 35) of bipolar electrical biosignals (ExG), analogue biosignals (GSR, RESP, TEMP, etc.), movement activity and location (EMG, IMUs, GPS, etc.), behaviour inputs (pedals and push buttons), and communication inputs / outputs (LPT, digital, etc.). Its great multi-sensory versatility, its simplicity of use, comfort for the researcher and for the end-user, as well as its optimisation to work in mobility conditions, open a wide range of possibilities to use it both in the laboratory and in outpatient research applications out of the laboratory.
This biosensor acquisition system comes with the Bitbrain Software Kit for data acquisition and programming, which has a large compatibility with real-time I/O and third-party data processing (LSL, Matlab, Python, BCI2000, OpenVibe, etc). Also, by acquiring the Human Behaviour Research Lab, it can be performed a seamless synchronisation with other human monitoring technologies such as EEG, eye-trackers, indoor positioning system, among many others.
This ultralight (172gr) biosignal amplifier, can be placed on the arm, waist or leg of the user to allow total freedom of movement. With 21+ channels (extensible to 35ch) it can simultaneously record up to 35 physiological variables.
Active shielding with optimised DRL to improve SNR and reduce artefacts. Bipolar electrical biosignals (ExG), analogue biosignals (GSR, RESP, TEMP, etc.), movement activity and location (EMG, IMUs, GPS, etc.), behaviour inputs (pedals and push buttons), and communication inputs / outputs (LPT, digital, etc.) can be monitored simultaneously, providing great flexibility and versatility to the researcher.
The amplifier can be placed on the arm, waist, leg, etc. and the sensor setup follows the standard procedures with intuitive operation, and with a minimal learning curve. It comes with a powerful software platform to collect data with the help of visual cues to assure quality montage and monitoring.
