Abstract
The present disclosure provides a biometric ring comprising an inner surface configured to adjoin a living being and a plurality of conductors circumferentially arranged about the inner surface. The conductors are configured to emit current and measure voltage across conductor path pairs. The biometric ring determines corresponding conductor path resistances through the body and generates resistance maps from these measurements. A biometric reading is derived from the resistance maps, enabling non-invasive monitoring of physiological parameters.
