摘要： An apparatus for an irreversible temperature sensor for measuring a peak exposure temperature is fabricated by printing an admixture of conductive nanoparticles on a dielectric substrate (110) to form a film (120). The film (120) has an electrical resistance that is inversely proportional to the exposure temperature. The electrical resistance also irreversibly decreases as the exposure temperature of the film (120) increases. A portion (140) of the film is exposed (230) to a pulse of electromagnetic energy sufficient to render it substantially more electrically conductive than the portion (130) that was not exposed. In use, the peak exposure temperature is determined by measuring (250) the electrical resistance of the non-altered portion (130) of the film and the electrical resistance of the portion (140) that was exposed to the pulse of electromagnetic energy and subtracting (260) the electrical resistance of the altered portion (140) from the electrical resistance of the portion (130) that was not altered to provide a difference value. The peak exposure temperature is then calculated (270) as a function of the difference value.

摘要： A printed read-only memory (ROM) device (136) that consists of an array of memory resistors (210), a reference resistor (220), and an analog-to-digital circuit (240) is disclosed. Resistance values are dependent on the data to be stored in the read-only memory. During read operation, a resistor (210) is powered, activating a voltage divider between the powered resistor (210) and the reference resistor (220). The analog-to-digital circuit (240) reads the divided voltage level between the two resistors (210, 220), compares it to the voltage supply level, and interprets it into bits of memory data.
