Skin-like test models could help improve medical devices for people of all skin tones
Researchers in Finland have developed realistic, skin-like test models called 'optical phantoms' to improve the accuracy of medical devices across diverse skin tones. These models simulate human skin layers and blood flow to help calibrate sensors like pulse oximeters.
Why it matters
This technology addresses a significant health equity issue where existing medical devices often perform less accurately on darker skin tones.
