The present disclosure concerns a device for sensing at least one biological parameter (e.g., heart rate, heart rate variability) of a subject, the device comprising a contact surface configured for being brought into a contact with a skin surface of the subject. The device has at least one light source for illuminating the skin surface through the contact surface along an illumination source optical axis with illumination including at least one sensing wavelength, and at least one detector for detecting a response of said illumination at least at said wavelength, from the skin surface through the contact surface along a detector optical axis, and providing signals configured for determining said biological parameter based thereon, said illumination optical axis forming with said contact surface an acute included angle.

Sensing at least one biological parameter, e.g., heart rate or heart rate variability of a subject

The present disclosure concerns a sensor assembly for measuring displacement of a contact surface at least along a central axis of the assembly caused by pressure applied on the surface by the skin of a user during measurement of at least one biological parameter of the user.

Displacement sensor for use in measuring biological parameters

Sensing at least one biological parameter, E.G., heart rate or heart rate variability of a subject

Disclosed are a composite bio-parameter sensor assembly and a wearable device including same, for detecting vital signs of a subject person. The sensor assembly includes one or more sensors, mounted on an outer contact surface of the assembly, having a sensing surface to optically detect one or more parameters of a pulse of the subject. The sensor assembly further includes an additional sensor, facing an inner cavity of the assembly, for optically detecting displacement of the one or more outer sensors. The one or more sensors and the additional sensor are positioned on the opposite sides of a printed circuit board (PCB).
