A DEVICE, A SYSTEM, AND A METHOD FOR MONITORING BONE DENSITY

A device (100) for monitoring bone density comprises: a first electrode unit (110) comprising a first electrode area (116) to be arranged within a bone (102); a second electrode unit (130; 230) comprising a second electrode area (136; 236) to be arranged outside the bone (102), wherein the first (11...

Zusammenfassung:A device (100) for monitoring bone density comprises: a first electrode unit (110) comprising a first electrode area (116) to be arranged within a bone (102); a second electrode unit (130; 230) comprising a second electrode area (136; 236) to be arranged outside the bone (102), wherein the first (110) and the second electrode units (130; 230) are configured for being arranged such that an electrical signal between the first and the second electrode areas (130; 230) travels through a cortical bone portion (104) of the bone (102); an injection signal generating unit (150) configured to provide an injection signal for generating the electrical signal; and a measurement unit (160) configured to detect a measurement signal induced by the injection signal for determining an impedance between the first (116) and the second electrode areas (136; 236) as a measure of bone density.
