20130259746 | SURFACE ACOUSTIC WAVE SENSING DEVICE - A SAW sensor includes a substrate, first and second IDT on the substrate and a detector portion between the first and second IDT. The first IDT generates a surface acoustic wave in response to a high-frequency signal input. The second IDT receives the SAW from the first IDT, and converts the SAW to an electric signal and outputs the electric signal. A one pulse signal, which is input to the first IDT electrode, has an applying time that is at least as long as a delay time of a surface acoustic wave at the detector less an arrival time of a direct wave attributable to electromagnetic coupling between the first IDT and the second IDT electrode, and that is less than an arrival time at the second IDT of a third response wave of the surface acoustic wave from the first IDT. | 10-03-2013 |
20150017735 | Analyte sensor and analyte sensing method - A biosensor includes a detection element having an analyte detecting portion which is monotonically increased in mass in response to detection of an analyte; a reference element having a reference measuring portion which exhibits no reactivity to the analyte; a mixer which mixes a detection signal responsive to mass variations in the analyte detecting portion from the detection element and a reference signal from the reference element; a measurement which calculates two candidate phase-change values of a positive value and a negative value, from a signal mixed by the mixer in accordance with a heterodyne system, and determines a phase-change value from the two candidate phase change value by judging whether the phase is positive or negative based on temporal changes in signal strength; and a detection amount calculation portion which calculates a detection amount of the analyte based on the phase change value determined by the measurement portion. | 01-15-2015 |
