We show that such materials have high sensitivity, and sufficient short-term stability – provided careful mechanical design and materials selection are made - to allow fabrication of low-cost, robust sensors, with low processing temperatures compatible with electronics integration. Example load- sensing applications are a multi-axis wrist rehabilitation device and a knee prosthesis.Couches épaissesThick-film technologyPTFCouches épaisses polymèresPolymer thick filmsRésistances résine-carboneResin-carbon resistorsCapteurs piézorésistifsPiezoresistive sensorsCapteurs de forceForce sensorsCircuits imprimés organiquesOrganic printed circuit boardsPCBDériveDriftRéhabilitationRehabilitationGenouKneetext::conference output::conference proceedings::conference paper
