摘要:
A wrist temperature rhythm acquisition apparatus and method, a core temperature rhythm acquisition apparatus and method, and a wearable device are provided. The wrist temperature rhythm acquisition apparatus includes a data acquirer configured to acquire wrist temperature data of a user and external environment temperature data; and a processor configured to estimate wrist temperature rhythm data in which an influence of an external environment temperature is corrected, based on the acquired wrist temperature data and the acquired external environment temperature data.
摘要:
A method for inducing an activity of a user's autonomic nervous system is provided. The method includes steps of: (a) on condition that each of the user's reference heart rate information corresponding to each of active states of the user's autonomic nervous system is obtained, an inducing device, if a specific active state of the autonomic nervous system is selected by the user, acquiring first reference heart rate information of the user corresponding to the specific active state of the autonomic nervous system; and (b) the inducing device supporting a first vibration stimulus with a first period corresponding to the first reference heart rate information to be applied to the user, to thereby allow the user's real-time average cardiac interval to be synchronized with the first vibration stimulus.
摘要:
A bioelectrode including a plate, a first electrode disposed on a first side of the plate, and a second electrode disposed on the first side of the plate and separate from the first electrode. The bioelectrode further includes a first guard portion disposed on a second side of the plate, a second guard portion disposed on the second side of the plate and separate from the first guard portion, and a preamplifier configured to output a voltage signal based on a biosignal measured between the first electrode and the second electrode.

Disclosed are a biosignal measurement device and a capacitively-coupled active electrode. The capacitively-coupled active electrode includes an electrode face configured to form capacitive coupling with a subject in a non-contact manner to detect a biosignal, and a pre-amplifier disposed on a rear side of the electrode face and embedded in a porous insulator.
摘要:
An apparatus and method of removing common mode noise in the case of measuring a biosignal using a capacitive coupling active electrode (CCE) is provided. A frequency band of a common mode signal may interact with a shield voltage and thus, a frequency band of a biosignal may be compensated for.
