An alternating electric field responsive biomedical composite is disclosed that provides capacitive coupling through the composite. The biomedical composite includes a binder material, a polar material that is substantially dispersed within the binder material, and electrically conductive particles within the binder material. The polar material is responsive to the presence of an alternating electric field, and the electrically conductive particles are not of sufficient concentration to form a conductive network through the composite unless and until the composite becomes overcharged. Linvention concerne un composite biomédical sensible au champ électrique alternatif qui fournit un couplage capacitif à travers le composite. Le composite biomédical comprend un matériau liant, un matériau polaire qui est sensiblement dispersé dans le matériau liant et des particules électriquement conductrices dans le matériau liant. Le matériau polaire réagit à la présence dun champ électrique alternatif et les particules électriquement conductrices ne sont pas suffisamment concentrées pour former un réseau conducteur à travers le composite, à moins que et jusquà ce que le composite ne soit surchargé.
