Electronic circuitry has been developed to serve as an interface between an electronic tongue and digital input/output boards in a laptop computer that is used to control the tongue and process its readings. Electronic tongues were described in two prior NASA Tech Briefs articles: “Electronic Tongue for Quantitation of Contaminants in Water” (NPO-30601), Vol. 28, No. 2 (February 2004), page 31; and “Electronic Tongue Containing Redox and Conductivity Sensors” (NPO-30862), Vol. 31, No. 8 (August 2007), page 58. Electronic tongues can be used for a variety of purposes, including evaluating water quality, analyzing biochemicals, analyzing biofilms, and measuring electrical conductivities of soils.
