Technology behind AURA Strap 2
AURA Strap 2 uses BIA, or bioelectrical impedance analysis, to measure your body composition. A small electric current is sent through your body, and the impedance (resistance) to the current shows information about what you’re made of.
The AURA Devices R&D team did a study to test how accurate AURA Strap 2 was compared to a DEXA (dual-energy x-ray absorptiometry) body composition scan, the industry gold standard for scientists and health professionals.
AURA Strap 2 gets 95% accuracy* compared to the industry golden standard — DEXA scan, which is fantastic for a device intended for home and outdoor use.
