Versatile Bio

All the biosignals you need in one device.

Wearable amplifier designed for real-time, synchronized, and simultaneous acquisition of multiple biosignals.

What is included

Biosignals Amplifier

Lightweight amplifier with motion tracking, Bluetooth, and microSD storage. It can be worn on the arm, waist, or leg, enabling comfortable and versatile use.

Sensors

Supports simultaneous recording of electrical, analog, motion, behavioral, and communication signals, with improved SNR through active shielding and optimized DRL.
