ABSTRACT
Mechanical prosthetics have achieved advancement in esthetics and mechanical functions. However, their use for natural functionality requires modifications to achieve tactile feedback. Newly synthesized materials and technologies have brought the advancement in three critical interfaces, i.e., skin-inspired multifunctionality, signal transmission between prosthetics and nervous system, and stimulation and recording of the signal. Bioinspiration of the somatosensory system has shown great advancement in materials and technologies. This study shows the sensation of artificial skin for prosthetic interface as well as prosthetic strategies and state-of-the-art technologies. The use of artificial synapses, biomimetic sensing, and neural interrogation electronics enable the sensory feedback loop in prosthetics.
