The efficacy and legitimacy of Scientology's use of the E-meter has been subject to extensive debate and litigation and in accordance with a federal court order, the Church of Scientology now publishes disclaimers in its books and publications declaring that the E-meter "by itself does nothing" and that it is used specifically for spiritual purposes.

  • Frog galvanoscope

    The frog galvanoscope was a sensitive electrical instrument used to detect voltage in the late eighteenth and nineteenth centuries. It consists of skinned frog's leg with electrical connections to a nerve. The instrument was invented by Luigi Galvani and improved by Carlo Matteucci. The frog galvanoscope, and other experiments with frogs played a part in the dispute between Galvani and Alessandro Volta over the nature of electricity. The instrument is extremely sensitive and continued to be used well into the nineteenth century, even after electromechanical meters came into use.
