This paper describes the development of a biotelemeter for the measurement of the strain on the surface of a complete maxillary denture. A thick film hybrid circuit has been developed giving up to three channels of strain data from three separate semiconductor strain gauges. The telemeter has a volume of approximately 1.5 cm3 and has been incorporated into a maxillary denture to provide functional assessment of the denture. Recordings of surface strain in the denture have been made from a subject while chewing various foods and these are presented together with a simple analysis of them.
