Abstract
A content use monitoring system is provided for monitoring use of blister packaged contents. The monitoring device comprises an integrated circuit (), battery () and piezo-electric foil () or other transducer that can be attached to a existing blister package, in physical contact with their backing, via adhesive. When a content is expelled from a blister through the backing, the piezo-electric foil () or other transducer is deformed, generating an electrical signal. The integrated circuit () monitors the piezo-electric foil circuit for such signals, analyses them, and if they meet the programmed specifications, the time and other characteristics of the event are recorded in the integrated circuit's memory. The content use data can later be downloaded for analysis, education or clinical purposes via either a remote or contact reader.
