To insert the sensors into the FLEX Cap, we recommend placing it onto a mannequin head and inserting the sensors through the openings before placing it onto your participant’s head. It can take up to an hour to position all the sensors in your chosen configuration.
Repeat these three steps for all of the sensors in your chosen configuration.
Step 1
Hold the underside of the FLEX Cap. Then, stretch the material around the hole you’re inserting the sensor through.
Step 2
There are two ways to insert the sensors into the FLEX Cap.
To insert the sensor, push it upwards through the hole, then release the tension in the material so that it fits around the bottom half of the sensor; or
Turn the FLEX Cap inside out, stretch the hole over the sensor, then let the material retract into place around the plastic groove of the sensor.
TIPS:
Always ensure the sensor felt (saline only) faces inwards, towards the scalp, before inserting.
Most of the sensor should be on the outside of the FLEX Cap, and the felt pad should be on the inside, where it will rest against your participant’s scalp during your study.
Do not force the sensors through the openings.
Step 3
Adjust the material around the sensor until it is fully fixed in place.
