  • Human body wearable antenna having dual bandwidth
    Patent number: 9831544
    Abstract: Disclosed is a human body wearable dual band antenna. The disclosed human body wearable antenna comprises: a substrate; a zeroth-order resonance antenna formed on the bottom of the substrate, for receiving a signal from a wireless device which is implanted in a human body; and a micro strip antenna formed on the top of the substrate, for transmitting the signal to a wireless device which is external to the human body. The dual band human body wearable antenna according to the present invention can relay communications between the wireless device which is implanted in the human body and the wireless device which is external to the human body.

  • Magnetic tunneling junction and fabrication method thereof
    Patent number: 6848169
    Abstract: A fabrication method of a magnetic tunnel junction includes the steps of: forming a magnetic tunnel junction constructed having a first magnetic layer, a tunnel barrier formed at an upper surface of the first magnetic layer and a second magnetic layer formed at an upper surface of the tunnel barrier; and thermally treating the junction rapidly for 5 seconds˜10 minutes at a temperature of 200˜600° C. to re-distribute oxygens in the tunnel barrier and make the interface between the tunnel barrier and the magnetic layer to be even. The tunneling magnetoresistance and thermal stability of the magnetic tunnel junction can be improved through the rapid thermal annealing.
