Abstract:
A spectrometer chip for analyzing a fluid sample and a method of manufacturing the spectrometer chip are provided. The spectrometer chip includes a cell comprising a chamber in which the fluid sample is accommodated, and a spectrometer comprising a channel of silicon nitride, the channel being configured to resonate and transmit light that is emitted from the fluid sample, and the spectrometer being disposed on a surface of the cell. The spectrometer chip further includes a detector configured to detect the transmitted light.
Abstract:
An electronic device determines accuracy of an analyte concentration non-invasively by calculating an analyte concentration of an analyte from an in-vivo spectrum obtained non-invasively using a calibration model, generates a test calibration model based on feature vectors of the in-vivo spectrum obtained non-invasively from which a spectrum specific to the analyte have been subtracted, calculates a test concentration for the analyte from the in-vivo spectrum using the test calibration model, and analyzes the test concentration for the analyte using the test calibration model to determine the accuracy of the analyte concentration using the calibration model.
Abstract:
A biosignal processing apparatus and a biosignal processing method are provided. The biosignal processing method includes: detecting a biosignal of a subject; detecting status information; and determining a correlation between the biosignal and the status information.
Abstract:
The electronic device of the disclosure may include: a semiconductor optical amplifier configured to divide an outputtable wavelength band and output multiple laser lights having a designated wavelength band and designated power, a fixed array distributed Bragg reflector (DBR) grating configured to modify a wavelength of multiple laser lights and output multiple laser lights having a modified wavelength, and an output coupler configured to allow the modulated multiple laser lights to adjust an output direction and/or angle and output the modulated multiple laser lights to an outside of the electronic device.
Abstract:
Provided are apparatuses for and methods of measuring a biological signal. The biological signal measuring apparatus includes reference point sensors configured to detect signals detected from at least two reference marks on a surface of a subject and a biological signal measuring position detector configured to generate information about a biological signal measuring position based on the signals detected from the at least two reference marks. The biological signal measuring apparatus measures the biological signal according to the information about the biological signal measuring position.
Abstract:
Provided are a method and apparatus for processing food information. The method may include detecting, by a sensor, food information of food consumed by a subject from blood of the subject in a non-invasive manner; and determining, by a processor, a digestive capacity of the subject based on the detected food information.
