WMU researchers in the Center for Advanced Smart Sensors and Structures (CASSS) needed an electroencephalograph (EEG) sensor system that could be worn for an extended period. The Flexible EEG Sensor is a 3d printable sensor that can read electroencephalographic waves without giving long term use strain to the wearer. In addition to comfort, the sensors must also be accurate and are benchmarked against commercially available ones. The initial design involved flexible sensors that would bend at the edges to give more surface area on the scalp and solid sensors that would give more surface area without bending. The sensors were coated with a silver paint layer then a flexible conductive epoxy. This would allow for flexibility and durability. It was found that the sensors have a conductivity of 7.70 E+03 S/m. This is less than out of the box sensors but still provides a quality signal to be practical. The sensors were tested against the out of the box EEG sensors using a neural network to test for eye blinking and jaw clenching. The new sensors could reliably send a signal to the neural network.
