Abstract: Provided are a barcode nano-wire for decoding a hard magnetic segment by using highly sensitive magnetic sensors and a bio-sensing system using the barcode nano-wire. Integration of hard magnetic and non-magnetic segments produces the barcode nanowire and magnetic segments are detected using highly sensitive magnetoresistance sensors. The non-magnetic segment uses a non-magnetic material and a specific biomolecule for bioanalysis is immobilized at a specific portion of the barcode nano-wire. The hard magnetic material has an advantage of higher coercivity and high remanence magnetization, which is considered as an important parameter in selecting the material. The hard magnetic segments produce distinguishable strong stray fields for individually detecting segments using conventional magnetic sensors for multiplexed bioanalysis.

Abstract: A routing method in consideration of the power and transmission delay in a wireless ad hoc network and a terminal device adopting the same are provided, which can reduce the power consumption and packet delay by considering both the power consumption and packet delay. The terminal device includes a judgment unit that determines whether a first accumulative hop count included in a first route request (RREQ) packet exceeds a predetermined route decision value for limiting a hop count from a source node to a destination node, and a control unit that determines a route to the source node, based on information included in the first RREQ packet, if the judgment unit determines that the first accumulative hop count does not exceed the route decision value.

Abstract: Provided is a magnetic sensor for detecting a magnetic field. The magnetic sensor includes a magnetic layer of a closed loop shape; a pair of current terminals which face each other contacting with the closed loop and through which current is input/output; and a pair of voltage terminals which face each other contacting with the closed loop and from which output voltage is detected. Both an anisotropic magnetoresistance effect (AME) and a planar Hall effect (PHE) contribute to the output voltage and a hysteresis of the output voltage is eliminated by exchange coupling of a ferromagnetic layer by a ferromagnetic-antiferromagnetic layer structure and a ferromagnetic-metal-antiferromagnetic layer structure. Accordingly, it is possible to minimize a hysteresis due to a demagnetization factor of the closed loop, stabilize the output voltage of the magnetic sensor and enhance sensitivity.
