The test requires patients to pinch or break the capsule, releasing the oil-filled fragrance, testing whether they can correctly determine the scent. 

The capsule users showed more correct answers when determining the scents rather than a scratch-and-sniff test. The scents include mint, orange, clove, coconut, cherry or onion. 

The engineers and neurologists behind the creation published a paper in the Journal of the Royal Society Interface, explaining its creation.
