MORE TIME FOR RESEARCH

Your questions. Your tools. Your data.

Designed to work together

Electronics, enclosure, firmware and software, with the aim of reducing the time you spend on assembly.

Your analysis tools

Open formats and integration with your software. LSL through Signalino Suite to share recordings.

More possibilities within your budget

A compact format and an affordable cost are design goals, including when you need several acquisition points.

TWO STORIES, ONE IDEA

EEG AND BIOSIGNALS · 2:24

Ana wants to do research.

More analyses, different measurements and multiple participants, without spending all your budget and time setting up equipment.

Read the transcript
This is Ana. She wants to study the brain. She gets an EEG system, buys the software and starts recording. Now she has signals. But no budget left. The data raises new questions. But her software cannot run the analyses she needs. She wants to use her usual tools. Proprietary formats and export restrictions get in the way. She also wants to record gaze and responses, and relate them to brain activity. But the programs work separately, and outdated connections make synchronisation difficult. Recording several people at once would save time. But more equipment means more cost. She looks for cheap boards. Now the numbers seem to add up. Until she has to sort out the cables, firmware, battery, enclosure and software. Then repeat the assembly. And synchronise everything. The days go by. Ana wanted to do research. Now she is building the equipment. That is why we are creating Signalino S3. A compact, affordable platform, with a device, enclosure, firmware and software designed to work together. We are designing it to make recording setup simple: connect the electrodes, configure the session and start. Without weeks of assembly. With open formats and access to your data. Eight channels and twenty-four bits to acquire biosignals, view them and record them. And analyse them with your own software. With LSL through Signalino Suite to combine measurements and coordinate recordings from several people. More analyses. New measurements. More participants. And your time, spent on research. Signalino S3. Your questions. Your tools. Your data. We are looking for partner laboratories to try the first prototypes. Tell us about your project.

CHRONIC RECORDINGS · 2:57

Marcos wants to expand his experiment.

More recording stations and the freedom to analyse his signals, while following the experiment from his office.

Read the transcript
Marcos studies how brain activity changes over days and weeks. To understand it, he makes chronic recordings in mice. He has a recording cage, a wall-mounted amplifier and a computer. The system works. But his questions keep growing. Now he wants to compare more animals. Try another condition. Record several at once. One more cage. Another amplifier. Another computer. And once again, the budget. When he adds up everything he needs, there is hardly any money left for the rest of the experiment. His ideas grow faster than his budget. Marcos also wants to analyse the signals with the software he already uses. But the equipment’s software has its limits. And getting the data out is not always easy. His questions change. The tools he bought do not. So he looks for a cheaper alternative. And finds boards that seem perfect. Small. Affordable. They just need assembling. Connect the cables. Set up the power supply. Program. Fix errors. Then do it again for each station, and get them all working together. Marcos wanted to study the brain. Now he is debugging connections. Expanding your experiment should not exhaust your budget. Or force you to become an engineer before you can do research. That is why we created Signalino S3. A compact, affordable platform, with hardware, enclosure, firmware and software designed to work together. A Signalino beside each cage, connected to the preparation’s electrodes. For these recordings, you power it with a phone charger. And the data reaches the computer wirelessly. Eight channels and twenty-four bits to acquire your biosignals. With LSL, open formats and your own software: Python, MNE, BCI2000, OpenViBE. To save your recordings and take them wherever you want. Now Marcos follows the experiment comfortably from his office. On screen: camera images and signals from each animal. More time to understand what is happening. Less time getting everything to work. Signalino S3. Your questions. Your tools. Your data. We are looking for partner laboratories to try the first prototypes. Tell us about your project.

FROM RECORDING TO ANALYSIS

Your software. Your way.

Signalino Suite and the Python API are part of the Signalino platform, including the new S3. View your signals, save your sessions or bring acquisition into your own tools.

Signalino Suite

The desktop application lets you connect the device, check impedances, view EEG and record sessions.

Installers are available in Preview for macOS Apple Silicon, Windows x64 and Linux Ubuntu/Debian amd64. Available features depend on the model, firmware and operating system; integration with S3 hardware will be evaluated with the first prototypes.

Installation notes and limitations

Python and your analysis tools

The Python API lets you bring acquisition into your software. It supports USB, Bluetooth Classic or Bluetooth Low Energy depending on the device; S3 is designed for USB and BLE.

python -m pip install signalino

Optional add-ons for LSL, MNE and the viewer can be installed with:

python -m pip install "signalino[all]"
Python API and instructions →

Share signals. Connect your experiment.

Lab Streaming Layer (LSL) lets applications share data and place their recordings on a common time reference. Signalino Suite can send EEG to compatible applications on the same computer or local network.

For example, you can record EEG and use another application to mark when an image appears or a sound plays. LSL helps relate both recordings so you can analyse the signal around each event.

You do not need LSL to view and save sessions in the Suite. It is there when you want to combine Signalino with other tools.

An open ecosystem

The platform uses 33-byte binary frames compatible with the OpenBCI format. The integration with BrainFlow is a release candidate, while the integration with BCI2000 is still undergoing validation.

The repository brings together downloads, documentation and release notes. Scignals programs and supports devices directly during this phase; public firmware packages have not yet been released. Installing the Suite does not update the firmware.

SIGNALINO TAKES SHAPE

Eight channels to explore your ideas.

At the heart of Signalino S3 are the ADS1299 and ESP32-S3: eight 24-bit channels in a compact device designed to work with your own tools.

EEG to study brain activity, EMG to record muscle activity and ECG to observe cardiac activity. Different bioelectric signals—ExG—on one platform.

Signalino brings together custom electronics, an enclosure, firmware and software developed as one platform. We are looking for partner laboratories to try Signalino in their experiments and explore its possibilities together.
