A ultimate mobile solution
for EEG

TMSi Mobita

Mobile EEG or BCI applications

Mobita is a compact 32-channel physiologic signal amplifier system from TMSi. Mobita brings new meaning to signal quality, starting with an impressive set of specifications wrapped in a battery operated, palm sized package. This makes the Mobita perfectly suitable for mobile EEG or BCI applications.

TMSi Mobita

Active shielding technology

Mobita features proprietary active shielding technology from TMSi for clean signals and data completely free of mains interference and cable movement artifacts. Mobita has extremely low noise characteristics and is perfect for demanding measurement setups and environments.

TMSi Mobita

Battery operated

TMSi Polybench is a software application toolbox, a veritable blank canvas for the creation of customized configurations; from basic measurements to sophisticated research applications. The possibilities are limited only by your imagination.

TMSi Polybench can be considered a personalized “application factory” allowing the user to control the high-quality raw data input from any TMSi amplifier to build the exact system they need. Choose among TMSi Polybench pre-set functions and controls or build customized processes in pursuit of practically any conceivable desired outcome.

In research, by definition, the questions being asked have specific challenges that off-the-shelf software often cannot be adapted to meet. TMSi Polybench allows you complete freedom in design so that data collection, measurement and manipulation is completely under your direction and not limited by the design of any specific software offering or system manufacturer.

TMSi Polybench can accept input from all TMSi amplifiers.

Interface for MATLAB

The TMSi MATLAB Interface is a library for MATLAB written by TMSi to interface the TMSi PC Driver to MATLAB. This interface allow you to acquire data, write and read. poly5 files via MATLAB and/or export data to EEGLAB (http://sccn.ucsd.edu/eeglab/).

Functionality that is included in the TMSi MATLAB Interface is limited to the signal acquisition part of the driver and loading data from previously recorded data in TMSi Polybench or the TMSi MATLAB Interface. All functionality needed to perform on-board memory recordings (so-called ambulatory measurement) as present in the Mobita, Mobi and Porti is NOT implemented.

The code in the TMSi MATLAB Interface is a MATLAB library for sampling TMSi devices. The goal of this library is to give an easy programmable interface to TMSi devices. It contains basic examples that should be enough to get you started.

The library provides:
• Sampling from USB, Wi-Fi, network and Bluetooth TMSi devices.
• (Limited) Real-Time plotting of sampled data.
• Directly saving sampled data to .Poly5 file format.
• Offline export of .Poly5 data to EEGLAB.
• Support for sampling using SynFi and Fusbi.

Note that TMSi does not support usage of the TMSi Interface for MATLAB.

The interface is distributed under MIT license, but can not be supported by TMSi support personnel.

Compatible with the following devices: REFA Extended, REFA, Mobita, Mobi, Porti.
