The pressure-detecting system utilizes a nanocomposite sensor with quantum dots embedded in a matrix. Under pressure, both the quantum dots and the matrix fluoresce when illuminated by a laser. A spectroscope detects the intensity of each fluorescence and sends the information to a data processor. The data processor calculates a ratio using the intensities. Comparing this ratio to ratios stored in a data object in a database provides a value for the pressure detected by the sensor. The data object contains multiple ratios, each correlated to a specific pressure during a calibration process for the sensor. This calibration process subjected the sensor to known pressures, with the resultant ratios calculated and stored in the data object, correlated to the appropriate pressures.
