The paper presents the idea behind the implementation of the BioSiP system designed for monitoring biomedical parameters and the patient's behaviour, based on the architecture of a measurement module system located on the subject's body. The system could be developed owing to the market launch of new generations of electronic devices combining high functionality, small size and low power consumption...
The increasing demand for innovative systems, used for monitoring the biomedical parameters and comfortable for the patients, leads to the provision of better and better solutions. This paper presents the latest system design for the measurement of psychophysiological parameters for comprehensive use, developed at the Institute of Medical Technology and Equipment in Zabrze (ITAM), in light of previous...
In this paper a gradual investigation of a particular Hall sensor in SOI (“Silicon-On-Insulator”) technology is presented. The most important parameters of a specific Hall cell, based on SOI structure, are evaluated through three-dimensional physical simulations. The fact that the depth of the active silicon layer in SOI integration process is much smaller than in a regular CMOS is immediately reflected...
A stable reference voltage (or current) source is a standard component of today's microelectronics systems. In particle physics experiments such reference is needed in spite of harsh ionizing radiation conditions, i.e. doses exceeding 100 Mrads and fluences above 1e15 n/cm2. After such radiation load a bandgap reference using standard p-n junction of bipolar transistor does not work properly. Instead...
The design of a 450nW bandgap temperature sensor in the 0 to 175°C range is presented. The design demonstrates a leakage current compensation technique that is useful for low-power designs where transistor performance is limited. The technique mitigates the effects of leakage in Brokaw bandgap references by limiting the amount of excess current that is entering the bases of the main bipolar pair due...
Thermal characterization techniques require precise powering and accurate data acquisition equipment. The proper powering is complex due to electrical and thermal stability issues and some device properties. A few methods require trials to ensure the proper powering of the devices. New compound semiconductor devices have further stability issues at low currents and high voltages. This paper analyzes...
This paper describes development and testing of the measurement system designed for a purpose of monitoring the heat flow, as well as humidity penetration in structures based on innovative building materials. At the beginning, the novel building materials and techniques, including nanotechnology-based ones are briefly presented, then vision of the structure monitoring system is described. Next, details...
