Table 1

Basic concepts of the human and artificial somatosensory system.

Human somatosensory systemArtificial somatosensory system

MechanoreceptorSensory cells, including Merkel cells, Ruffini endings, Meissner corpuscles, and Pacinian corpuscles, respond to mechanical pressure or distortionHaptic sensorMeasures information arising from physical interaction with the environment. These sensors are generally modeled after the biological sense of cutaneous touch
ProprioceptionProvides information about the body’s position and the state of the muscles and limbsMotion planningFinding a sequence of valid configurations that moves the object from the source to the destination
Nerve fiberAfferent nerve fibers and efferent nerve fibers that conduct action potentials away from the nerve cell bodySignal transmissionThe transduction mechanisms of haptic sensors could be classified into capacitive, piezoresistive, piezoelectric, optical, and magnetic
Cerebral cortexNeural integration in the central nervous system. It plays a key role in attention, perception, memory, language, and consciousnessArtificial intelligenceMimics “cognitive” functions that humans associate with the human mind, such as “learning” and “problem solving”
