eSense Muscle & eSense EEGenius SDK in C# for Unity – App development, e.g. for VR applications
This is our eSense SDK (Software Development Kit) for developing your own software using Unity Framework in C# for the eSense Muscle and eSense EEGenius. Develop your own applications with up to two channels of EMG or EEG and connect via Bluetooth to a PC, laptop, smartphone/tablet or VR headset.
This SDK includes a demo app in Unity and our easy-to-use decoder library, as well as either an eSense Muscle or eSense EEGenius of your choice. These are the same device with different firmware configuration.
A short documentation can be found here: ESenseUnityExample-V1-0-0

- HF Filter
- Operating mode: Continuous operation
- Measuring accuracy EMG amplifier / ADC
- Gain: ยฑ 5 % basic accuracy, ยฑ 0.2 % after calibration
- Bandpasses lower and upper cut-off frequency: ยฑ 0.1 %
- Sampling frequency: better than ยฑ 0.1 % (resonator)
- Operating range: 5-40 ยฐC, <= 95% relative humidity
The technical details of the eSense EEGenius:
Identical to the eSense Muscle, but differs in the following points:
- 10 frequency band filters from delta…artifact, 25 Hz transmission rate per frequency band and channel
- Raw signal transmission with 2 kHz sampling
- Real-time impedance measurement for both channels, parallel to measurement
