Abstract:
A sensor device laser synthesized directly onto a monolithic wide-bandgap semiconductor compound substrate, the combination comprising:a. a monolithic wide-bandgap semiconductor compound substrate responsive to laser synthesis conversion; b. a delineated pattern inscribed on a first surface of said substrate, having input and output ends, by a controlled focussed laser beam defining a thermoresistive sensor having resistive properties in the range of 109 to 10âˆ’6 ohm-cm, with said resistive properties being responsive to environmental changes applied thereto; and c. at least two conductors inscribed on said first surface of said substrate, one of said conductors connected to said input end of said delineated pattern and another connected to said output end thereof, to thereby provide electrical connections to said thermoresistive sensor.
