Field: Medical technology (Instruments)
Classification: CPC G  A | IPC A  G

Claim 0:
1. A mat that senses an object on the mat, the mat comprising:
a substrate;
a sensor array that is disposed on the substrate and that includes a plurality of fiber sensors, each of the plurality of fiber sensors configured to generate a signal based on a distance between the object and the fiber sensor;
a shield layer that covers the sensor array;
a drive unit configured to apply a voltage to the sensor array;
a plurality of connection electrodes that are disposed at an edge of the substrate and electrically connect the plurality of fiber sensors with the drive unit; and
a shield portion disposed at the edge of the substrate, the shield portion having a shape that surrounds the plurality of connection electrodes and being configured to block an electromagnetic field to thereby restrict an impedance change of the plurality of connection electrodes based on a distance change between the plurality of connection electrodes and the object,
wherein the plurality of fiber sensors are disposed at opposite ends of the substrate and at a central portion between the opposite ends of the substrate.
