Present electrochemical CO2-sensors are basically modified pH-electrodes; the operating principle of which is based on the measurement of a potential that is effectively a linear function of the logarithm of H+ ion concentration. The relationship between pH and PCO2 is delta pH = 0.97 delta log 10PCO2. Since one unit of pH at room temperature corresponds to less than 60 mV potential change, it is obvious that the PCO2 measurement is intrinsically inaccurate. In addition, this method is not conductive to miniaturization and it is susceptible to the same basic problems associated with the pH-electrode, i.e. low sensitivity, slow response and considerable drift. The feasibility of developing a new electrochemical carbon dioxide sensing method based on the reductive adsorption of CO2 onto a noble metal electrode and the subsequent anodic oxidation of the 'Reduced-CO2' species has been investigated experimentally. It was established that under proper conditions the presence of oxygen does not interfere with the measurement of CO2 concentration.

"PH and Brain Function offers thorough coverage of this increasingly important area of research, beginning with the fundamental concepts, which include methodological and theoretical issues such as the measurement of pH and the concept of pH in neurobiology. It explores aspects of regulation and modulation of intracellular pH in brain cells, surveys the changes in pH that occur with neural activity and how these changes affect neural activity, and discusses the role of pH in the pathophysiology of neurological diseases." "pH and Brain Function is an important resource for researchers in all areas of neuroscience as well as cell biology and physiology." --Book Jacket.

The present invention generally relates to carbon dioxide (CO.sub. 2) sensors. In one embodiment, the present invention relates to a carbon dioxide (CO.sub. 2) sensor that incorporates lithium phosphate (Li.sub. 3PO.sub. 4) as an electrolyte and sensing electrode comprising a combination of lithium carbonate (Li.sub. 2CO.sub. 3) and barium carbonate (BaCO.sub. 3). In another embodiment, the present invention relates to a carbon dioxide (CO.sub. 2) sensor has a reduced sensitivity to humidity due to a sensing electrode with a layered structure of lithium carbonate and barium carbonate. In still another embodiment, the present invention relates to a method of producing carbon dioxide (CO.sub. 2) sensors having lithium phosphate (Li.sub. 3PO.sub. 4) as an electrolyte and sensing electrode comprising a combination of lithium carbonate (Li.sub. 2CO.sub. 3) and barium carbonate (BaCO.sub. 3).
