SENSOR FOR MEASURING A UV DOSE AND METHOD FOR MEASURING A UV DOSE USING SAID SENSOR

摘要

The invention relates to a sensor (1) for measuring a received UV dose. To this end, the sensor (1) includes a transistor (2) of the MOS type with a floating grid. The transistor (2) includes a grid (G), a drain (D), a source (S), as well as a floating grid (FG). According to the invention, the received UV dose is calculated from the measure of a variation in the intensity (di) of the current (i) flowing through the drain (D) of the transistor, or from a variation in the threshold voltage (Vs', Vs') of the transistor between, before and after exposition to UV radiation.
