The EPOC Flex gel kit includes 34 EasyCap multi-rode gel sensors that are pre-configured and easy to setup. The sensors are made from sintered Silver/SilverChloride for minimising the electrode impedance. The sensors are attached to length of tinsel wire and terminated with JST gold plated crimps. This length is designed to be long enough to reach any position on the cap.
Sensor wires are colour coded, blue for left, red for right and black for references. In addition each sensor will be individually labelled with the channel name it is connected on the EPOC Flex. The aim of this colour coding is simple, when troubleshooting you can quickly identify the colour and channel name in the software and quickly find the electrode on the cap. For example if contact quality is low on channel LA this corresponds with the blue A wire.
The sensor wires are in two lengths to help to minimise the excess but also allow for any configuration, channels A-G are 300mm and channel J-Q are 150mm. Once you have fitted all the sensors in place we recommend that you use the included tagger pins and tagger tool to tidy up the wiring (See link). Or we recommend that you place a cap over the top to stop these wires catching. If your research involves minimising motion artefacts you should keep the excess wire secured.
We know that researchers can have different needs for references, so we have included ear clips and the gel sensors are compatible with adhesive pads.
