摘要:
A system and method are provided for determining the fat to lean ratio of body tissue. An actuator is used to apply a force and measure a compression, so that at least two force-displacement relationships are measured. From the two force-displacement relationships and known elasticity values of fat and lean tissue, a fat to lean ratio or thickness ratio of the body tissue is obtained. In particular, fat tissue thickness and lean tissue thickness may be resolved. The system may be applied in the home with minimal training and with high safety.

A method (200) and a device (100) for detecting body fat using near infra-red energy is disclosed. The method includes transmitting infrared energy (210) at a set of wavelengths to a body and determining a set of values (220) indicative of energy reflectance of the infrared. Further, the method includes determining a set of ratios (230) based on the set of values, wherein the values are based on reflected infrared energy from the body. Subsequently, a fat percentage of the body is determined (240) based on the set of ratios and a statistical model. The statistical model associates a set of reference body fat percentages to the set of ratios. Further, the device (100) may include an energy radiation device (110) to irradiate the body with near infrared energy and an energy receiving device (120) to receive near infrared energy reflected by the body.

摘要:
A flexible weight sensor which includes a plurality of flexible capacitive weight sensors and at least one flexible-resistive-pressure-sensor, each flexible capacitive weight sensor exhibits a respective dynamic range of the response to a respective range of weights. The flexible capacitive weight sensors are arranged in a stack. The linear dynamic range respective of each the flexible capacitive weight sensors starts at a weight not higher than the saturation point of the linear dynamic range of the flexible capacitive weight sensor above it. The at least one flexible-resistive-pressure-sensor is coupled between each pair of flexible capacitive weight sensors. Each flexible-resistive-pressure-sensor measures information relating to the saturation weight of the flexible capacitive weight sensor above the flexible-resistive-pressure-sensors, when the weight of a load applied on the weight sensor exceeds the dynamic range of the flexible capacitive weight sensor above the flexible-resistive-pressure-sensor.
摘要:
Methods of detection of steatosis are described that utilize a Raman spectrometer with a near-infrared excitation laser and a detection range associated with the C-H bonds of triglycerides. Methods of analysis of such spectra are also presented, as are methods of screening or evaluating the quality of organs for transplantation purposes.
摘要:
A fat tissue observation method includes: a process A of applying an optical clearing agent to fat tissue within a body; a process B of heating the fat tissue to reduce a first refractive index of the fat tissue and put the first refractive index close to a second refractive index of the optical clearing agent; and a process C of observing an inside of the fat tissue that the optical clearing agent permeates.
