a question

Evening all,
A question for any who have actually investigated this stock. Can anyone tell me why this tech is actually better than the existing? Now I know it is more sensitive but is this needed? Current tech works well eg all the sensors in mobile phones, Nest, IoT's biological and chemical sensors - so I don't see it replacing these. What are the uses that this will be put to that current tech can not do?

I understand that having multiple sensors would be an advantage if they can do it. I am really just interested in the uses of the increased sensitivity.

Thanks for your help

Cheers all

DYOR please
