Abstract: A method of measuring a tissue element, a device of measuring a tissue element, and a wearable apparatus are provided. The method includes: determining a positioning feature; determining a measurement region according to the positioning feature, where the measurement region meets a reproducibility of a measurement condition; arranging the measurement probe at a position corresponding to the measurement region; and performing a tissue element measurement by using the measurement probe.

Abstract: A method of measuring a tissue element, a device of measuring a tissue element, and a wearable apparatus are provided. The method includes: irradiating a measurement region with incident light having at least one predetermined wavelength (S110), where each beam of the incident light is incident on an incident position to form at least one beam of exit light exited from at least one exit position on the measurement region; and arranging an anti-jitter portion at a position corresponding to the measurement region, so that an average optical path of exit light received by a measurement probe associated with the anti-jitter portion is maintained within a predetermined optical path range during a skin jitter process at the measurement region (S120).

Abstract: A non-invasive detection method, device, system and wearable apparatus for tissue element are provided. The method includes: emitting incident light of multiple predetermined wavelengths to a detected site, respectively; for each predetermined wavelength, obtaining light intensity values emitted from a surface of the detected site based on multiple photosensitive surfaces, wherein multiple photosensitive surfaces are at predetermined distances from a center of the incident light; and determining a concentration of the tissue element to be detected according to light intensity values in multiple predetermined wavelengths.
