Having an electronic body part (6)
I believe the answer is:
bionic
'having an electronic body part' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for bionic that I've seen before include "With e.g. powered limbs" , "Of person or faculties, operated by electronics" , "Having an electronic body part" , "Using electromechanical body parts" , "Using electromechanical body enhancement" .)
