Abstract
Technology was developed for fabrication of a calcium sensor on the ba sis of a field-effect transistor with a Ta2O5 gate, a poly(vinyl chlor ide) membrane based on di-n-octylphenylphosphoric acid and its calcium chelate, and an intermediate polymer coating. The sensor has operatin g characteristics similar to those of a calcium-selective electrode wi th similar membrane composition and is not sensitive to pH in the 5-9 range. The service life is no less than 4 months.
