Haptics is the study of the sense of touch. Touch has many parts, but the most basic, the most fundamental of all, is that of pressure.
A surprising find that pure touch-based sense organisms like hydras and jellyfish are capable of detecting changes in light levels in localised areas, strongly suggests that sight developed as part of the touch sense - and that some form of sight sensor is ideal when proprioception is not workable.

Shape memory alloys are composite materials which can 'remember' a given shape or form, and revert back to it when a charge is passed through them, or they are warmed past a critical point, or another condition is met. They deform then reform, essentially flowing like organic tissue without actually being organic.
