Biomedical device, systems and methods having conductive elements
View Patent ↗A device for determining a physiological property of a body includes an insulating support having a compliant contact surface with a conductive element to contact the body. A mounting fixture disposed over a mounting surface of the support removably holds a rigid sensor spaced apart from the body and coupled to the conductive element to determine the physiological property via that element. A method for enabling a physiological parameter to be measured without direct contact between an active device and the body includes arranging a conductive element over an inner surface of an insulating circumferential band. A sensor with the active device is attached to the exterior of the band and thus coupled to the element. A system includes the sensor having a mounting connector, and sensor carriers with respective supports, mounting fixtures, and conductive elements. The sensor mounted on a carrier determines the property via the respective conductive element.
