(A) A biological mechanosensory nerve. Mechanoreceptors receive pressures and change receptor potentials. The nerve fiber of a sensory neuron generates action potentials depending on the receptor potential changes. The action potentials are delivered through biological synapses to next neurons at a spinal cord.
(B) An artificial mechanosensory nerve. Pressure sensors, organic ring oscillators, and synaptic transistors mimic biological mechanoreceptors, biological neurons, and biological synapses, respectively. The same colors represent corresponding parts.
(C) A photograph of an artificial mechanosensory nerve.
