Abstract
A non-contact/non-destructive technique for determining the mechanical properties of coated drug tablets is presented. One method is to detect, monitor and characterize a drug tablet during compaction by means of transmitting and receiving acoustic waves into the powder core, as it is formed in a press (compactor), via transducers embedded in the compactor die and punches. An iterative computational procedure is shown that extracts the mechanical properties of the coated tablet from a subset of its measured resonance frequencies. Sensitivities of the resonance frequencies to changes in the tablet mechanical properties is illustrated and discussed. These non-destructive techniques require no physical contact with the tablet and operate in the microsecond time-scale. Therefore, they can be employed for rapid monitoring and characterization applications.
