SQUIDs (Superconducting QUantum Interference Devices) are the most sensitive known sensors of magnetic field. Measurements with SQUID-based magnetometers are though expensive, which leads to attempts at replacing them with magnetometers cheaper in use. Research on atomic sensors CSAMs (Chip-Scale Atomic Magnetometers), that can be used in room-temperature, seems promising. Measuring method and possible applications of CSAMs are presented.

SQUIDy, czyli nadprzewodzące interferometry kwantowe (ang. Superconducting QUantum Interference Devices), są aktualnie najczulszymi znanymi czujnikami pola magnetycznego. Magnetometry oparte na detektorach SQUID są jednak drogie w eksploatacji, co doprowadziło w ostatnich latach do próby zastąpienia interferometrów kwantowych magnetometrami tańszymi w obsłudze. Obiecujące wydają się być badania nad atomowymi sensorami CSAMS (ang. Chip-Scale Atomic Magnetometers), które mogą być stosowane w temperaturze pokojowej. W artykule przybliżono zasadę działania oraz możliwości aplikacji magnetometrów atomowych do badania czynności różnych narządów.

SQUIDy, czyli nadprzewodzące interferometry kwantowe (ang. Superconducting QUantum Interference Devices), stanowią najbardziej czułe znane aktualnie czujniki pola magnetycznego. Ze względu na możliwość pomiaru niezwykle małych wartości indukcji magnetycznej wykorzystywane są między innymi w pomiarach biomagnetyzmu. W artykule przedstawiono możliwość aplikacji oraz metody pomiarów magnetycznych przy użyciu czujników SQUID do badania czynności różnych narządów organizmu.

Recording of the image of the radiating biofield of electrostatic nature on the photosensitive film was made by using an electrographic installation, working under high voltage and low intensity conditions (25-30 kV; 3.5-10 myA), ascending slope monoimpulse, condenser with flat plates, specific cabling. The method initiated by J. Narkevicz (1910), rediscovered by Kirlian (1952), developed by F. Dumitrescu and E. Celan (1975), applied in the study of ontogenesis by C. Guja (1981), used in the experiments on the plant behaviour by M. Godeanu (1983), is presently used in electrographic diagnostics of various medical affections ( Anthropological Research Center of the Romanian Academy) and in some special cognitive experiments (USA, Russia, Germany). The film and electromorphous effects that delimit effluvionary structures with specific density and distribution are generated by the biological field belonging to the surface and inside of the organism. The almost periodical shape of the envelope of the electrographic biological signals (streamers) that belong to the frontier of the palm surface, allowed the determination of its analytical expression, using the theory of aleatory functions, almost periodical in probability. The electrographic results were put into functional connection with neuronal activity, the electroencephalographic signals also having a periodical envelope curve. In the paper, there has been worked out a cybernetic control and regulation diagram of the cerebral waves, using the electrographic-electroencephalographic assembly as well as the medical control unit for cerebral waves by means of luminous signals. The electrographic information was quantified, while the electrographic test was considered an experiment, its results (biological signals) making up an event field with various achievemnt probabilities. The electrographic informational calculation method was applied to some lots with psycho-neuro-endocrine and cardiovascular deseases and to some lots consisting of aging subjects. The comparison was made with the results obtained with the witness lots, introducing the term of compared informational electrography (ClEg). The investigation was made on the palm surface, considering that it best reflects the bioinformational dynamics of the human individual. One may highlight an electrographic informational law, the results being useful for the prospective prefiguration and diagnosing of various affections occuring in some processes specific ofhomeostasis. We determined the mathematical law by means of which its elements are generated; one may attach the human being participating values, corresponding to the hydric, mineral, dielectric, semiconducting components. Isomorphism existing between these components and the biofield forms, recorded electrographically, were highlighted.
