  • Publication number: 20250044375
    Abstract: A method for measuring DC bias aging characteristics of a multilayer capacitor includes applying a first poling voltage to a multilayer capacitor including a body having a dielectric layer including a plurality of dielectric grains and an internal electrode disposed alternately with the dielectric layer in a first direction, and an external electrode disposed on the body, maintaining the first poling voltage for a first period of time (t1), applying a DC bias voltage lower than the first poling voltage, maintaining the DC bias voltage for a second period of time (t2), and measuring saturated capacitance after the DC bias voltage is applied.

  • Patent number: 9945739
    Abstract: Provided are a flexible pressure sensor using an amorphous metal and a flexible bimodal sensor for simultaneously sensing a pressure and a temperature. The sensors according to an exemplary embodiment of the present invention include a conductive layer formed of the amorphous metal to have stretchable characteristics so that it may be used for an electronic skin. Therefore, these sensors may firmly maintain conductivity and sense a pressure or simultaneously sense a pressure and a temperature even in a state in which various kinds of physical external force are present. In addition, the flexible bimodal sensor according to an exemplary embodiment of the present invention is a novel element for an electronic skin that may simultaneously sense a pressure and a temperature using the amorphous metal.
