Features & Specifications
Precise and highly configurable sensor hardware
- Can be configured to use up to 32 electrodes.
- Measures at 160,000 samples per second.
- Each impedance measure is made using differential referencing and 16-bit resolution.
- Includes automatic temperature calibration to ensure impedance accuracy.
- Includes an accelerometer for motion mitigation.
Built for safety and ease-of-use
- DC power removal filters meet IEC60601-1 safety specifications.
- Compatible with a 3.5 V, 850 mAh battery (not included) for improved portability. On-board circuitry allows charging via the supplied USB cable. Up to 12 hours of battery life, depending on the specific use case.
- Support for Bluetooth Low Energy (BLE) to accommodate wireless data transmission.
Flexible open source software
- Easy to install software supports time series impedance measurements, bio-impedance spectroscopy, and electrical impedance tomography, between 80 Hz and 80 kHz, with up to 32 electrodes.
- Supports three different types of tomographic reconstruction: Graz Consensus, Gauss-Newton Method, and Back Projection. All three can be run in realtime and can be configured with any number of electrodes (e.g., 8, 16, or 32). You can record for analysis offline, and run in real-time.
- Hardware includes Serial Wire Debug (SWD) programmers for easy firmware re-programming.
- Tiny, portable PCB measures approximately 2” by 2” and comes with a plastic enclosure.
- Comes with a small, cylindrical ‘phantom’ tank (140 mm diameter, 60 mm height).
- Comes with a flexible electrodes for imaging things that don’t fit in the phantom.
