Abstract :
This paper reports on novel, fully polymeric capacitive strain gauges and their biomedical applications. The sensor devices are designed for the measurement of strains above 30% and continuous recording of length changes. Specifically the determination of ligament and tendon elongation at the human knee joint is shown here. The concept, fabrication, testing and successful application of these sensors is described, together with results of a first cadaveric in vitro study. Further applications and the possible impact for biomechanical studies are discussed.
