Abstract: A process and device are disclosed for sensing the thermal interaction between the human body and the disclosed device. The thus obtained physical measurement data are electronically converted and may be associated in an appropriate manner to concentrations of certain components of human blood determined in an unambiguous manner, such as cholesterol, triglycerides, etc., in particular glucose. The device has at least one heat measurement unit and electronic control, regulation, evaluation and output units. The device also allows temperature measurements with high spatial and temporal resolutions. The process is non-invasive and is particularly suitable for determining without contact the glucose concentration in parts of the human body, in particular human blood.

Abstract: A device is suitable both for determining with high accuracy and precision the temperature of the human body (surface temperature, temperature in layers next to the surface, temperature in bodily cavities, temperature gradient towards the inside of the body) and for detecting output units. Their measurement accuracy and precision is higher than that of conventional temperature and heat measurement devices. The device further allows temperature measurement and heat detection with a high spatial and temporal resolution. In addition, because of the high correlation discovered between the glucose concentration in human blood and body temperature and heat measured at certain points of the body, the device is extraordinarily suitable for non-invasively and even contactlessly determining the glucose concentration in parts of the human body, in particular the human blood.
