Posturograph - measuring amplifier

A posturographic platform is a versatile research device used to examine the organ of balance.

A quadruple strain gauge measuring amplifier was developed, with an output over a USB port or with a built-in BlueTooth module.

The board carries four instrumentation amplifiers, a 10 V voltage regulator supplying the strain gauge bridges and a 5 V to 12 V converter driven from a microcontroller output. A 12-bit SAR analog-to-digital converter is fitted on the board, which provides precise measurements with low interference and noise.
