Abstract: A wearable electronic device includes a signal capturing assembly and a holder. The holder includes a case defining a receiving slot configured for receiving the signal capturing assembly, a first connecting electrode, and a second connecting electrode. The first and second connecting electrodes protrude from a bottom surface of the case and are electronically connected to the signal capturing assembly. The first and second connecting electrodes detect vital signs of a user and transmit the detected vital signs to the signal capturing assembly.

Abstract: A wearable electronic device includes a signal capturing assembly and a wearable assembly. The signal capturing assembly is configured for detecting and processing vital signs from a user and defines at least one port. The signal capturing assembly includes a base, a first cover, a second cover, a third cover, a first electrode, and a core module. The first, second, third covers cover the base to form a receiving chamber to accommodate the core module. The first electrode is extended through the base and electronically connected to the core module The wearable assembly is detachably connected to the signal capturing assembly through the at least one port.

Abstract: A wrist-worn bracelet displaying health indicators constructed to ensure correct and optimal fitting on a wrist of user for the effective detection of functioning of human body. The wrist-worn bracelet includes a first wristband portion and a second wristband portion connected to the first wristband portion to form a closed loop. The second wristband portion includes at least one inwardly-bent portion. A contour of the at least one inwardly-bent portion is capable of being changed by heating and bending the inwardly-bent portion so that an inner diameter of the closed loop is adjustable.

Abstract: In a mood analysis method using an electrocardiogram of a user, RR intervals in the electrocardiogram are computed, and low-frequency (LF) values and high-frequency (HF) values are also computed according to the RR intervals. Standard values of sympathetic nervous system (SNS) activity and parasympathetic nervous system (PSNS) activity are acquired corresponding to age and sex data of the user, to establish a mood display coordinate system. Coordinates of the LF values and the HF values in the mood display coordinate system are computed to determine a mood of the user.

Abstract: In a breathing analysis method using an electrocardiogram of a user, a breathing curve is generated according to R waves in the electrocardiogram, and whether the user is currently taking a breathing out action or a breathing in action is detected according to the breathing curve. A duration of the breathing in action or the breathing out action of the user is computed according to the breathing curve, and a ratio of the duration and a standard time of the breathing in action or the breathing out action is computed. A breathing in or out progress is displayed in a progress demonstration bar on the display device according to the ratio.
