OBJECT PROXIMITY AND CONTACT DETECTION DEVICE

摘要

[Problem] Provided is a device capable of detecting contact with or proximity to a living organism without greatly constraining the behavior of the living organism. [Solution] The proximity or contact detection device of this invention is provided with an application unit for applying an electrical signal to an application-side conductor disposed in proximity to a living organism, a measurement unit for detecting an electrical signal produced by application by the application unit to a measurement-side conductor disposed in proximity to the living organism and generating a reception signal that includes signal intensity, and a state estimation unit for estimating the proximity state between living organisms on the basis of the reception signal and a preset estimation equation. The proximity or contact detection device is disposed in proximity to a series of objects in which the application side conductor and the measurement side conductor have an electrical resistance no greater than that of the skin of the living organism.
