What is bionics then?

'Bionics' is along with 'biomimicry' and 'biologically inspired design' synonymous with biomimetics.

However, bionics in the english speaking world normally refers to something more specific, namely; the replacement or enhancement of organs or other body parts by mechanical versions.

Bionic implants differ from mere prostheses by mimicking the original function very closely, or even surpassing it.

In other countries, and especially German speaking ones (bionik), the word bionics covers the exact same meaning as biomimetics (is used insead of biomimetics).
