Figure2. Braille reading using an artificial mechanosensory nerve
(J) An artificial mechanosensory nerve with a pressure sensor array of 2 × 3 pixels. Ring oscillators and synaptic transistors were connected to the pressure sensors and process the pressure information.
(K) The outputs of the artificial mechanosensory nerve in (J) when a braille character "E" was pressed.
(L) The performance of artificial mechanosensory nerves with and without synaptic transistors. The synaptic transistors help our system to distinguish braille characters clearly.
Figure3. Movement controls using the connection between an artificial sensory (afferent) nerve and biological motor (efferent) nerves
(A) An insect and an artificial mechanosensory nerve used in this experiment.
(B) An artificial mechanosensory nerve was connected to biological motor nerves to make a hybrid reflex arc and control the movements of a detached insect leg.
(C) The experiment set-up used to measure the force of the movements of the disabled insect leg.
