Study on temperature dependence of output voltage of electrochemical detector for environmental neutrinos

An electrochemical detector with biological material has been applied for the detection of neutrinos on the basis of a new hypothesis. The detector consisted of two electrodes with raw silk and purified water, and gave an appreciable output voltage. The reproducibility of the experimental results was as good as 99.4% at temperature of 300 K, The temperature dependence of the voltage of the detector was studied at 280, 290, 300 and 310 K, Among them, the detector at 310 K produced the highest output voltage and reached 104 mV in 16 days, whereas that at 280 K generated the lowest voltage and it was as low as 1,2 mV in 16 days, The detectors working at 290 and 300 K produced the voltages 18 and 57 mV in 16 days, respectively. The output voltages of the detector increased with temperature and were in good agreement in spite of the history of temperature. The internal resistance and electromotive force (internal voltage) of the experimental detector were obtained at each temperature by individual analysis and least square fitting method. It was found that the electromotive force was almost constant for these temperatures while the internal resistance showed a large dependence on temperature. The reduction of the output voltage with temperature is dominated by this behavior of internal resistance.
