Infochemistry and infofuses for the chemical storage and transmission of coded information

摘要

This article describes a self-powered system that uses chemical reactions-the thermal excitation of alkali metals-to transmit coded alphanumeric information. The transmitter (an "infof use") is a strip of the flammable polymer nitrocellulose patterned with alkali metal ions; this pattern encodes the information. The wavelengths of 2 consecutive pulses of light represent each alphanumeric character. While burning, infofuses transmit a sequence of pulses (at 5-20 Hz) of atomic emission that correspond to the sequence of metallic salts (and therefore to the encoded information). This system combines information technology and chemical reactions into a new area-"infochemistry"-that is the first step toward systems that combine sensing and transduction of chemical signals with multicolor transmission of alphanumeric information.
