Mindfield SDK for eSense Muscle / EEGenius for App Development in C# for Unity

Who is this SDK for?

For developers integrating muscle (EMG) or brain activity (EEG) into Unity projects – from VR/AR biofeedback and neurofeedback games to research and training applications. You get calibrated data streams in real time and a ready-made Unity demo project.

What’s included

• eSense Muscle (EMG) — muscle activity in microvolts (µV), 2-channel, frequency bands Broadband (20–950 Hz) / Mid (20–300 Hz) / Narrow (100–200 Hz) as µV RMS, via Bluetooth
• eSense EEGenius (EEG) — brain activity in microvolts (µV), 2-channel, raw signal 250 Hz/channel; plus 10 frequency bands (transmitted at 20 Hz): Delta (0.5–4 Hz), Theta (4–8 Hz), Lo-Alpha (8–10 Hz), Alpha (8–12 Hz), Hi-Alpha (10–12 Hz), Lo-Beta (12–15 Hz), Beta1 (15–19 Hz), Beta2 (19–23 Hz), Hi-Beta (23–27 Hz) and Artifact (52–58 Hz); plus per-channel impedance display, via Bluetooth
• eSense SDK in C# as a download by email
• One test device (eSense Muscle or eSense EEGenius) with electrode cables and electrodes in a case
• Demo application in C# with a demo Unity project
• Documentation and technical support by email
• Unlimited commercial and non-commercial use, no royalties

Technical specification

The two sensors

EMG & EEG live in the data stream

Examples from the eSense demo: muscle activity (EMG) with frequency bands and brain activity (EEG) with band-passes and impedance display – the same data streams you process in Unity.

One plugin for mobile, VR and desktop

The Unity C# plugin is cross-platform: the same codebase runs on iOS and Android, on standalone VR headsets (Meta Quest, Pico – Android-based) and on the desktop. This lets you feed EMG and EEG signals into immersive and interactive applications.

Use cases

• VR/AR biofeedback — physiological signals drive immersive experiences on Meta Quest / Pico
• Neurofeedback games — EEG-driven serious games with the eSense EEGenius
• EMG training applications — muscle activity as input in Unity
• Research projects — real-time EMG/EEG capture in your own Unity setups
