Build your own apps with eSense
The eSense biofeedback sensors are an open developer platform. With our SDKs and plugins you can build your own applications — for partners and OEM integrations, scientific research, commercial products, immersive VR experiences and personal gadgets.
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 — audio 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.
| Platform | Skin Response | Temperature | Respiration | Pulse | Muscle | EEGenius |
|---|---|---|---|---|---|---|
| MobileiOS & Android | native SDK | native SDK | native SDK | standard Bluetooth | Unity plugin | Unity plugin |
| VRQuest & Pico | native SDK | native SDK | native SDK | standard Bluetooth | Unity plugin | Unity plugin |
| Windows.NET 10 | native SDK | native SDK | native SDK | native SDK | native SDK | native SDK |
| macOSSwift | native SDK | native SDK | native SDK | standard Bluetooth | Unity plugin | Unity plugin |
Pulse uses the standard Bluetooth heart-rate service and needs no SDK. Muscle (EMG) & EEGenius (EEG) run through the single Unity C# plugin on mobile, VR and desktop.
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 v4.0 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 accessed through a single Unity C# plugin on mobile, VR and desktop. 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.
Partner, research or commercial project?
Whether you are building a commercial product, an OEM integration or a research setup — we are happy to support your development.
