Description

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.

• eSense SDK in C# as download by e-mail
• eSense Muscle or eSense EEGenius device with electrode cables + electrodes in case
• Demo application in C# with demo Unity project
• Documentation
• Technical support by e-mail.

The technical details of the eSense Muscle:

• Bluetooth 5.0 Low Energy, downward compatible up to 4.0
• 2-channel EMG biofeedback device
• Built-in Li-Ion battery 1600mAh for up to 12 hours of uninterrupted operation
• 2 bipolar EMG inputs (CH1+, CH1-, CH2+, CH2-), 1 x analog ground
• 2 multifunction buttons for operating the appliance
• 1 RGB LED to display the operating status
• 24 bit ADC and preamplifier for each channel
• Native sampling with 2 kHz per channel.
• 3 bandpass filters (Bessel, 8th order) per channel. -3dB cut-off frequencies: BP1: 20..950Hz, BP2: 20..300Hz, BP3: 100..200Hz
• RMS calculation and moving average over 0.5 seconds. Decimation to 100 RMS samples per second
• 200mV differential measuring range per channel
• 0.024 μV ADC resolution per LSB
• < 1.7 μV RMS noise BP1
• < 1.3 μV RMS noise BP2
• < 0.8 μV RMS noise BP3
• Channel 1 and 2 CMRR at 50Hz and 60Hz: better than -105dB
• Protection against electrostatic discharge (ESD) up to +-15kV according to the “Human Body Model”, IEC 1000-4-2, Air-Gap Discharge
• HF Filter
• Operating mode: Continuous operation
• Measuring accuracy EMG amplifier / ADC
• Gain: ± 5 % basic accuracy, ± 0.2 % after calibration
• Bandpasses lower and upper cut-off frequency: ± 0.1 %
• Sampling frequency: better than ± 0.1 % (resonator)
• Operating range: 5-40 °C, <= 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

Who is this package suitable for?

Software developers who want to integrate our eSense Muslce or eSense EEGenius into their own applications with little effort and want to take their own EMG/EEG measurements or create biofeedback / neurofeedback apps.
