Distributed Pressure Sensing as Smart Mat Applications with Hetero-Core Fiber Optic Nerve Sensors


Article Preview

Distributed pressure sensing schemes for human positioning and plantar mapping is desired to be unconstrained for human activity in their daily life in the form of a floor and mat. On the other hand, an optical fiber has several advantages such as lightweight, minimal material, and resistance to corrosion and electromagnetic interference. Additionally, a novel hetero-core optic fiber nerve sensor is only sensitive to be bending action of the sensor portion and the fiber transmission line is unaffected to external disturbance as pressure and temperature fluctuation because of its single-mode stable propagation scheme. Therefore, the hetero-core fiber optic sensor could be suitable for the distributed pressure sensing in human natural activity and be placed in various sites. In this paper, we proposed several smart mat applications in the form of a thin mat in the floor for human positioning and sole pressure mapping mat using the hetero-core optic fiber sensors. We successfully demonstrated the distributed pressure sensing mat using hetero-core sensors to detect human positioning with their circumstance and sole pressure mapping.
