Abstract: A resonator includes a resonating body and at least one periodic structure having one end connected to the resonating body. The periodic structure includes at least two basic structure units with duplicated configuration. The periodic structure blocks wave propagation caused by the vibration of the resonating body. The resonating body has a resonance frequency f0. The periodic structure has a band gap characteristic or a deaf band characteristic within a particular frequency range, and the resonance frequency f0 falls within the particular frequency range of the periodic structure.

Abstract: A biosignal measurement module is provided and includes a biosignal measurement unit, a pose detection unit, and a processing unit. The biosignal measurement unit measures an electrocardiogram signal and a pulse signal of a subject. The pose detection unit detects a position of the biosignal measurement module and outputs position signals. The processing unit receives the electrocardiogram signal, the pulse signal, and the position signals. The processing unit generates a height variation parameter, which indicates the height difference between the position of the biosignal measurement module and a reference position, according to the position signals. The processing unit calculates a current pulse transit time according to the electrocardiogram signal and the pulse signal and compensates for the current pulse transit time according to the height variation parameter to obtain a compensated pulse transit time. The processing unit obtains a blood pressure signal according to the compensated pulse transit time.

Abstract: A urine detection system is provided for detecting degree of wetness of a diaper, comprising a plane printing electrode, a sensor, and a display unit. The plane printing electrode comprises a first electrode area and a second electrode area. The sensor comprises a first sensor electrode, a second sensor electrode and a processor. Wherein the first sensor electrode and the first electrode area forms a first capacitor, and the second sensor electrode and the second electrode area forms a second capacitor. The processor, detects capacitance of the first and second capacitors, and determines a signal representing degree of wetness of the diaper. The display unit receives the signal and displays the degree of wetness corresponding to the signal.
