The present invention relates to a nano-dynamic biosensor and a fabrication method therefor. A biosensor according to the present invention comprises a substrate having a hollow structure and a graphene layer formed thereon wherein a probe material is bound to the surface of the graphene layer and the resonance vibration of the hollow structure formed in the substrate is modulated as the probe material increases in weight when a target material to be detected is coupled to the probe material without being labeled, whereby the biosensor is expected to take advantage of the modulation to measure the coupling of the target material including vaccinia virus with high sensitivity on a femtogram (10g) level.

Nano-dynamic biosensor and fabrication method therefor

The present invention relates to a sensor for sensing hydrogen. The sensor of the present invention comprises: a core which reacts with hydrogen to change a resistance value; at least two electrodes connected to the core; and a variable resistor which is connected to at least one of the two electrodes and of which the resistance value changes in response to a control signal, wherein the core includes palladium having a thin film shape, and graphene which is applied on the palladium and has a thin film shape.

Sensor

Provided is a non-destructive inspection device for pressure containers using leakage-flux measurement, including: a coil winding mount disposed at one side on an outside of the pressure container to magnetize the pressure container; a sensor support provided with a plurality of magnetic field sensing sensors arranged at the other side on the outside of the pressure container; a yoke magnetizing the pressure container to generate a magnetic flux in a direction vertical to a direction of the magnetic flux generated by the coil winding mount; an endoscope attached with at least one magnetic field sensing sensor, and the like.
