Key Contributions:

Au-Zone was responsible for the complete system architecture, hardware design and base firmware implementation based on the product requirements. The client, then worked closely with the Au-Zone project team to implement additional software features and functionality.

This design required very detailed attention to low noise analog design techniques in order to accurately resolve the micro-volt EEG signals at the same quality as a laboratory instrument. Special attention to low power techniques was also required to achieve the target battery life in both the wireless streaming and data logging modes of operation.
