DEEP-FRY OIL QUALITY SENSOR

摘要

A cooking oil quality sensing apparatus and system includes an acoustic wave sensor comprising one or more acoustic wave transducers configured upon a piezoelectric substrate such that when the acoustic wave sensor is in contact with cooking oil, the sensor generates acoustic wave data indicative of the quality of the cooking oil. An antenna can be integrated with the acoustic wave sensor, such that the antenna receives data an external source and transmits the acoustic wave data indicative of the quality of the cooking oil to the external source. An oscillator can be integrated with the acoustic wave sensor, such that the output of the oscillator contains data indicative of the quality of the cooking oil. The acoustic wave sensor can be coated with a material that is selectively sensitive and/or reactive to one or more fatty acids associated with or contained in the cooking oil.
