The right path for your project

📱

Mobile apps

iOS & Android — native or cross-platform via the Mobile SDK, Flutter or Capacitor.

🥽

VR apps

Meta Quest & Pico (Android-based) — audio sensors via the Unreal plugin, EMG & EEG via the Unity plugin.

🖥️

Desktop

Windows (.NET 10 — all 6 sensors natively) and macOS (Swift — all 6 sensors natively).

🎮

Game engines

Unity (audio + BLE plugins, all sensors) and Unreal Engine 5.4 (audio sensors).

The six eSense sensors

Three sensors stream over the audio input, three over Bluetooth. A wireless Bluetooth variant of the audio sensors is in development (see roadmap).

Sensor coverage per platform

How you reach each sensor on each platform — natively via the platform SDK, via standard Bluetooth, or via the Unity C# plugin.

Pulse uses the standard Bluetooth heart-rate service (no SDK required) and is also native in the mobile SDKs. Muscle (EMG) & EEGenius (EEG) run natively in the Windows, Android and iOS/macOS SDKs — and via the single Unity C# plugin for Unity and VR apps.

Biofeedback in virtual reality

Modern VR headsets are standalone Android devices, so the eSense plugins run directly on the headset. Stream physiological signals into immersive applications in real time.

Wireless Bluetooth variant of the audio sensors

We are developing a Bluetooth version of the previously audio-based eSense sensors — removing the audio adapter and making the sensors even easier to integrate into mobile and VR applications. Planned availability: first quarter of 2027.

Developer FAQ

Can I develop my own app for the eSense sensors?

Yes. The eSense biofeedback sensors are an open developer platform with SDKs and plugins for iOS, Android, VR (Meta Quest, Pico), Windows, macOS, Unity and Unreal Engine. You can build applications for research, commercial products, VR experiences or personal projects.

Which platforms and frameworks do the eSense SDKs support?

The eSense SDK Suite v5.0 covers mobile (native iOS/Android, Flutter, Capacitor), VR on standalone Android headsets (Meta Quest, Pico), desktop (Windows .NET 10, macOS Swift) and the Unity and Unreal Engine 5.4 game engines.

How do I read EMG (Muscle) and EEG (EEGenius) data?

Muscle (EMG) and EEGenius (EEG) stream over Bluetooth and are native in the Windows, Android and iOS/macOS SDKs — in Unity and VR apps they are reached through a single Unity C# plugin. Muscle offers bandpass modes (20–950 / 20–300 / 100–200 Hz); EEGenius provides Delta, Theta, Alpha and Beta bands at 250 Hz per channel.

Where do I get the eSense SDK and can I use it commercially?

The eSense SDKs are available as products in the Mindfield shop and may be used for commercial products, OEM integrations and research. For partner or OEM enquiries, contact info@mindfield.de.
