Abstract
A bio-thermo sensor has an enzyme-modified membrane directly supported on an IC thermal detector in face-to-face contact. The enzyme-modified membrane selectively reacts with a specific chemical substance to generate therein a reaction heat which is converted into an amplified output voltage indicative of the chemical substance by the IC thermal detector. The IC thermal detector includes Darlington-connected transistors which provide high sensitivity and quick response time.
