Provided is a sleep guidance device that serves to control a stimulus imparter for imparting stimuli to a human subject. The sleep guidance device acquires a biorhythm of the human subject; estimates sleep depths of the human subject from the acquired biorhythm of the human subject; and controls the stimulus imparter to impart a stimulus to the human subject in accordance with the acquired biorhythm of the human subject, and from among the sleep depths, a current sleep depth estimated for the human subject.

A pressure sensing mat may include: a first substrate; a second substrate disposed opposite to the first substrate; a first electrode layer disposed on a side of the first substrate that faces the second substrate, the first electrode layer comprising a plurality of first electrode patterns; a second electrode layer disposed on a side of the second substrate that faces the first substrate, the second electrode layer comprising a plurality of second electrode patterns; and a spacer layer disposed between the first substrate and the second substrate and comprising a plurality of holes such that the first electrode patterns are configured to contact the second electrode patterns through the holes.

A composite membrane, a biosensor, and preparation methods thereof are disclosed. In the preparation process, a moldable and plastic material is used as a carrier; after a dispersion liquid of a nanocarbon material wets the carrier, by means of multiple stretching and folding processes, the nanocarbon material is uniformly distributed and arranged regularly inside the entire plastic material in a stretching strain direction. The prepared composite membrane is elastic, attachable, and cost-efficient, and may detect strains as high as 530%. The composite membrane further has high sensitivity and high durability, and may be effectively applied to a biosensor for monitoring motion and humidity.

An approach is provided for matching vital sign information to a concurrently recorded data set according to a time domain. The approach involves determining sensor information collected from one or more sensors configured to monitor one or more vital signs of one or more objects within a monitored area. The approach also involves processing and/or facilitating a processing of the sensor information to detect the one or more objects and to track the one or more vital signs of the one or more objects over a time domain. The approach further involves matching the one or more vital signs of the one or more objects to a concurrently recorded data set based on the time domain. The approach further involves storing at least one record of the one or more vital signs matched to the concurrently recorded data set.

According to an embodiment there is taught herein a system and method of noncontact human vital signs monitoring using light sensing (also referred to generally herein as visible light sensing (VLS)) that can, in some embodiments, measure in real-time breathing (respiration) and heartbeat rates without body contact. One variation comprises a photo-detector (PD) sensor, which measures signal power level of the reflected light signal from the patient's body and an embedded processing system for the signal processing and filtering on the received light signal. The technology taught herein has the potential to address numerous conditions where the use of contact-based devices may be problematic.

A respiratory state estimation apparatus estimates whether a respiratory state is equivalent to a first respiration including normal respiration or a second respiration smaller in respiratory ventilation volume than the first respiration. The apparatus includes an acquisition unit, a detector, a calculator, and an estimator. The acquisition unit acquires an electrocardiographic waveform of a user. The detector detects amplitudes of R waves in the electrocardiographic waveform. The calculator calculates a spectrum of the amplitudes by performing transform processing with respect to the amplitudes in a time width in which the spectrum has a spectrum shape with a peak in the first respiration and a spectrum shape without a peak in the second respiration. The estimator estimates a respiratory state of the user based on the spectrum.
